Abstract

Improvement of rice panicle architecture is one important objective in the development of improved new-plant-type rice varieties. Panicle architecture is directly related to yield components in rice. The aims of this study were to obtain information on inheritance pattern of panicle architecture on F2 generation and to obtain the best selected individuals. The experiment was conducted at Sawah Baru Experimental Farm Bogor, from May to October 2016. Two F2 populations derived from crosses of IPB 3S/IPB160-F-36, IPB160-F-36/IPB 5R and three genotypes of parents were used as experimental materials. A total of 208 and 204 plant samples were taken representing each of the two F2 populations and 20 plants representing the parents. Three panicles were taken randomly from each individual as observed samples. The results showed that additive gene action influenced number of primary branches in population of IPB 3S/IPB160-F-36, whereas in the population of IPB160-F-36/IPB 5R, most of the panicle architecture traits were controlled by additive gene action except for the length of primary branches. All of panicle architecture traits were controlled by relatively many genes except length of primary branches and number of grains on primary branches in the IPB 3S/IPB160-F-36 population. The panicle architecture of the two observed population was genetically varies. The heritability estimates were moderate to high. Selection could increase the mean of panicle architecture traits using either single or multiple traits simultaneously.Keywords: gene action, heritability, genetic variability, panicle traits

Abstract

Anther culture is useful tool in rice breeding. The technique shortens the time to obtain full homozygous plant in just one generation. Information related to genetic variability among the regenerants is important for further analysis including selection activities. The objective of this study was to analyze agronomic character variability and yield potential among doubled-haploid lines (DH0) derived from anther culture. This study was carried out in Center for Agricultural Biotechnology and Genetic Resources Research and Development (BB Biogen) from October 2016 to February 2017. The experiment was arranged in randomized complete block design (RCBD) with three replications. Forty eight doubled haploid lines derived from anther culture and three check varieties were evaluated. The results showed high genetic variability as well as broad sense heritability (more than 90%) for all variables tested. Several lines showed superior agronomic characters compared to check (Ciherang, Inpari 18, Inpago 10). Anther culture could generate high genetic variability for further selection.Keywords: anther culture, broad sense heritability, haploid technology

Abstract

AbstractRice lodging due to incident of extreme weather, i.e., combination of strong winds and high rainfall is eviden in Indonesia. However, yield loss in the area is rarely studied. In order to estimate yield loss on rice, a model for calculating the yield reduction was developed. The objective of present study was to analyze the effect of strong winds and high rainfall incidents on yield loss of rice in the field. The study was conducted at the Sawah Baru IPB, Bogor, Indonesia from February to April, 2016 on rice plots severe from natural incident of strong wind and high rainfall. The results showed that rice lodging from strong wind and high rainfall formed patterns and specific formations. We determined four major lodging formations,  five lodging degrees, and eleven different patterns due to wind direction. Overall, lodging occured on research area of 27.6% with production loss up to 11.89%. This research showed that estimation of yield loss due to incident of extreme weather could be conducted in the level of field based on area of coverage and degree of lodging. Application of the model on wider area needs further evaluation. Keywords: Agronomic character, extreme weather adaptation, modelling, lodging, rice variety

Abstract

Drought inhibits several physiological process and induces oxidative stress due to the enhanced production of reactive oxygen species (ROS) mainly in photosynthetic apparatus. Silicon (Si) is known to increase tolerance of rice against drought stress.  However, long period of intensive crop cultivation depleted the available soil Si by approximately 11-20%. Rice husk ash (RHA) is potential Si source. The objective of this research was to analyze the potency of RHA through pot experiment to observe: 1) internal water balanced; 2) integrity of cell membrane and  antioxidant content; and 3) production of tolerant cultivar ‘Segreng’ and sensitive one ‘Cempo merah’. Application of RHA was at level of 0, 4, and 8 tons ha-1. Drought stress was imposed by with holding water until soil water content reached 50% of field capacity (moderate stress) and 25% of field capacity (severe stress). Application of RHA significantly increased leaf relative water content and membrane stability index of rice ‘Segreng’ and ‘Cempo merah’. Tolerant cultivar ‘Segreng’ had better response than ‘Cempo merah’ as shown by greater leaf relative water content under moderate and severe stress. RHA application at level of 8 tons ha-1 increased index of membrane stability and level of antioxidant (AAred and α-tocopherol) which determine production of both rice ‘Segreng’ and ‘Cempo merah’ during drought.Keywords: antioxidant, field capacity, membrane stability, segreng cultivar, α-tocopherol

Abstract

Weeds can reduce upland rice yields in coastal sandy area. Density and growth of weeds can be controlled and reduced by an intercropping system between upland rice with soybeans. The study aimed to determine the weeds composition change and weeds biomass in various crop proportions of upland rice and soybean under intercropping. The research was conducted from December 2016 until March 2017, at coastal sandy soil of Samas, Bantul, Yogyakarta (8°00’03.5”S and 110°15’20.1”E). This study used a complete randomized block design (RCBD) with one factor and three replications. The treatments were crop proportions of upland rice and soybean under intercropping with 6 levels, such as 100:0 (upland rice monoculture), 80:20, 60:40, 40:60, 20:80, and 0: 100 (soybean monoculture). The results showed that there was weeds composition changes due to setting crop proportions of upland rice and soybean under intercropping at coastal sandy soil. Weed of sedges, grass, and broadleaf were found throughout the experimental plots, but varied in number and type of weeds among experimental plots. Weeds condition differed among the soybean proportion treatments < 40% and  ≥ 40%. The average community coefficient value was <75% which was dominated by Digitaria nuda and Eragrostis tenella under soybean proportion treatments < 40%, and Ludwigia parviflora and Amaranthus lividus under soybean proportion treatments ≥ 40%. The linear model was established between the increase of soybean proportion to a decrease in dry weight of weeds as Y = -0.6624X + 67.699; R2 = 0.7224).Keywords: crops proportion, intercropping, weeds community

Abstract

Study on soybeans morpho-physiological responses in artificial or natural shade are beneficial to determine the effects of shade on morpho-physiology and yield of soybean. This research was aimed to study the morpho-physiological responses of soybean varieties under shading of maize and cassava compared to arficial shading. The research was conducted in Kendalpayak Research Station, ILETRI, from February to May 2016 used split plot design with three replications. The main plot was three shade sources: N1:black paranet 50%, N2: maize shade, and N3: cassava shade, while the sub plot was five soybean varieties: Dena 1, Dena 2, Argopuro, Panderman, and Grobogan. Soybean varieties showed morpho-physiology differences depending on the shade source. Soybean grown under shading of cassava had plant height, leaf area ratio, and leaf area lower than under shading of paranet and maize. Cassava shade also caused soybean had higher growth rate, net assimilation rate, and yield than those under paranet and maize shade. Shade-tolerant varieties (Dena 1 and Dena 2) had high yield on all kind of shade. Less tolerant varieties (Panderman and Grobogan) had higher yield under cassava shade and lower yield under paranet and maize shade. Maize crop had similar shade effects with 50% paranet shade.Keywords: Glycine max (L) Merr., intercropping, Manihot esculenta Crantz, paranet, Zea mays L.

Abstract

Soybean (Glycine max L. Merrill) is an essential commodity due to its protein content and it is also as  functional  food which contains isoflavon as an antioxidants. Import policy is handled when there is a high demand of soybean in local market but lack of local production. This research aimed to study growth and yield of three  soybean varieties with differens watering intervals in paddy field under dry climate. This research was conducted in Sesela Village, Gunung Sari Sub District, District of West Lombok, Nusa Tenggara Barat Province from July to October 2015. This research used split plot design with three replications. The main plot was irrigation intervals every (2, 9, 16, 23, 30 days) and the sub plot was soybean varieties (Anjasmoro, Burangrang, and Tanggamus). The results showed that interaction between irrigation interval and varieties influenced plant growth and yield, such as plant height, number of leaves, leaf area, 100 seeds weight  and number of productive pod. Tanggamus variety has the highest number of pods of 146.33 and yield (4.2 ton ha-1) in paddy field. Keywords: number of leaves, productive pod, variety, yield

Abstract

Cassava is one of the important starch producer crops. Although Indonesia ranks as the third largest cassava producer country, Indonesia still imports cassava starch to meet the domestic demand in food and non-food industries. Gamma ray irradiation has been implemented to generate cassava mutants in order to support development of superior cassava variety, especially high yield and high starch content, especially high yield and high starch content. The objectives of this research were to evaluate the yield potential and the starch content of gamma irradiated 40 putative cassava mutants at M1V4 generation. This research was arranged in randomized complete block design with three replications and conducted at Cikabayan Experimental Field, IPB, Bogor, from May 2016 to March 2017. The starch content was measured using gravimetric methods. The results showed that five mutants, G2142, G3151, G2141, G1143, and G3111, had higher tuber weight per plant (6-7 kg per plant) compared to the background ‘Gajah’ genotype (4.7 kg per plant). ‘G2112’ mutant genotype showed higher starch content (23.86%) compared to the background ‘Gajah’ genotype (17.65%). The specific gravity (SG) was positively correlated with starch content (r = 0.905), indicated that the higher the SG, the higher the starch content of cassava.Keywords: gravimetric, mutant, specific gravity (SG), yield

Abstract

Drought stress during generative stage affected pod yield, yield components, seed and pod qualities of groundnut (Arachis hypogaea L.). The reseach was carried out to assess the effect of drought stress at various soil water availabilities during generative stage on pod yield, pod and seed physical qualities. The experiment was conducted at Muneng Experimental Farm, Probolinggo District during July-October 2012. Five genotypes were arranged in a RCB design, with 3 replicates. The replications were nested into four treatments of soil water availability (0-100, 0-85, 0-70,0-55 days after sowing/DAS). The pods were harvested at 102 days after sowing. The result showed that the shorter the water availability, the lower the leaf relative water content, pod and seed water contents, number of mature pods, seed size, and intact seeds weight. Pod yield reduced when water was available upto 55 DAS only. Turangga variety had the highest pod yield (1.626 ton ha-1) with low pod and seed physical qualities. GH-51 yielded in 1.076 ton ha-1 with superior pod and seed physical qualities. Despite of its lowest pod yield (0.964 ton ha-1), J-11 produced the same pod and seed physical qualities as GH 51 did. ICGV 86590 was superior on its pod yield (1.338 ton ha-1) with low pod and seed physical qualities. Kancil variety did not perform any superiority.Keywords: intact seeds, leaf relative water content, pod moisture content, seed moisture content
