Abstract

Development of doubled haploid lines of upland rice through anther culture is one way to obtain superior upland rice varieties tolerant to drought. The objectives of this research were to determine the response of doubled haploid lines to drought stress at seedling stage and to select tolerant doubled haploid lines. The research was conducted at a screenhouse of Muara Research Station, Indonesia Center of Rice Research (ICRR) from November to December 2017. Fourteen doubled haploid lines and 4 check varieties, namely Inpago 10 and Limboto, Salumpikit (drought tolerant check) and IR 20 (drought sensitive check) were used in this study. The experiment was arranged in a randomized complete block design with three replications. The observations were conducted on leaf rolling, leaf drought, and recovery ability. Based on Friedman nonparametric analysis, HR-5-7-1-1 and HR-7-15-2-1 had moderate response with estimated median values for leaf rolling of 3.44 and 3.00, respectively. Three doubled haploid lines namely HR-2-27-2-7, HR-2-34-1-3 and HR-7-15-2-1 had moderate response to drought with estimated median value of leaf drought of 3.56. Nine lines of doubled haploid had tolerant response with estimated median value of recovery ability of 1.00-1.56. Based on weighted selection index, nine doubled haploid lines with positive and high selection index were identified; however, only two lines (HR-7-15-2-1 and B3-2) had selection index higher than Inpago 10 and Limboto.Keywords: drought tolerance, leaf rolling, recovery, weighted selection index

Abstract

Leunca (Solanum nigrum L. ) is one of the indigenous vegetables in Indonesia. The fruit of this vegetable is green and has bitter taste because of its tannin content. The objectives of this study were to get lethal dose 50 (LD50), diversity and to obtain candidates of mutant plants with high and low tannin content in young fruit and ripe fruit in leunca. The research was conducted at Pasir Kuda experimental station, Bogor; National Nuclear Energy Agency (BATAN), Jakarta; and postharvest laboratory of the Center for Tropical Horticulture Studies (PKHT IPB), Bogor, from December 2016 to July 2017. Leunca accession of SN 20 and SN 29 were irradiated using doses of 0, 100, 150, 200, and 250 Gy of gamma ray. The LD50 values for SN 20 and SN 29 were 171.944 Gy and 190.949 Gy, respectively. The analysis of tannin content was performed based on permanganate method by titration using potassium permanganate. The results showed that the highest tannin content of green stage fruit was found in SN20D3.5 with 200 Gy dose and the lowest was found in SN29D1.5 with 100 Gy dose. The highest tannin content of ripe fruit was found in SN20D4.6 with dose of 250 Gy and the lowest was found in SN20D3.1 with dose of 200 Gy. Recommended tannin content for leunca is the low tannin content.Keywords: diversity, gamma ray, indigenous vegetable, irradiation, LD50

Abstract

Endosperm quantity in kopyor coconut determines the quality of kopyor coconut. However, data of the best parental based on their progeny test is unavailable yet. In this study, we employed polycross approach and SSR molecular marker to estimate general combining ability of the best pollen contributor for the breeding purpose of this trait. Totally 151 kopyor coconuts were collected from the naturally open-pollinated population of kopyor Tall coconut Agom Lampung. The harvested nuts were rated for their endosperm quantity (scored 1-9). The analysis identified 31 paternal trees of the 53 progenies. The TJ-185 with the highest GCA has been considered as a promising paternal tree for development of high endosperm quantity of kopyor coconut.Keywords: combining ability, molecular marker, paternal trees, polycross, tall coconut

Abstract

Stevia rebaudiana Bertoni, a sweetener plant, has been cultivated in Indonesia since the early 1980s, but the yield is lower than in other countries. Five selected introduced stevia clones were planted at Megamendung, Bogor, Indonesia (6°39’ S, 106°56’ E, 800 m above sea level) on December 2014 until November 2015 to evaluate their growth and biomass yield. The growth and yield were observed from 6 to 12 months after planting. In addition, stevioside, rebaudioside A (reb A), and total steviol glycoside (TSG) contents of leaves were measured using high performance liquid chromatography (HPLC). At six months after planting, stem diameter was 8-11 mm, plant canopy diameter was 23-30 cm, plant height was 24-35 cm, and plant mortality was less than 5% except for clone BU at 30.7% due to Sclerotium attack. The plants flowered at different times, therefore had different harvest durations, from 4 weeks (clone BM) to 8 weeks (clone BP). The highest leaf yield was clone BM (6.04 ton ha-1 per year), followed by BX (4.91 ton ha-1 per year), and BP (4.38 ton ha-1 per year). From the five clones tested, clone BM was the best for leaf, TSG, and stevioside yields; whereas clone BS and BP were the best for reb A yield. Keywords: rebaudioside A, Stevia rebaudiana, stevioside, total steviol glycoside

Abstract

Most of marginal lands in Indonesia are in the form of acid dry land with low available P and high Al concentrations. Development of tolerant rice varieties to P deficiency and Al toxicity is one way to increase rice production. This study aimed to select BC3F1-Pup1+Alt genotypes from three crosses based on foreground and background markers. This research was conducted at the Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development, Bogor, from August to December 2015. The materials used were 300 genotypes of BC3F1 Dodokan-Pup1+Alt, BC3F1 Situ Bagendit-Pup1+Alt, BC3F1 Batur-Pup1+Alt, and the parents. The research included selection in modified Yoshida’s nutrient solutions (0.5 ppm P dan 60 ppm Al) followed by foreground selection and background selection. Selection using Yoshida’s nutrient solution resulted in 150 genotypes with longer root than the recipient parent in each of the BC3F1 populations. Selection with foreground markers using markers RM1361 and RM12031 produced 85 genotypes of BC3F1 Dodokan-Pup1+Alt (56.6%), 105 genotypes of BC3F1 Situ Bagendit-Pup1+Alt (70%), and 77 genotypes of BC3F1 Batur-Pup1+Alt (51.33%). Selection using background markers revealed that genotype number 116 (BC3F1 Dodokan-Pup1+Alt), number 2 (BC3F1 Situ Bagendit-Pup1+Alt), and number 129 (BC3F1 Batur-Pup1+Alt) were the best genotypes with percentage of parent recovery of 95%, 90%, and 90.5%, respectively. These three genotypes were verified to have Alt loci and had the largest genetic proportion of restoring parents. Keywords: Alt, background markers, foreground markers, Pup1, upland rice

Abstract

Improvement of chilli’s quantitative traits requires several stages of breeding program, one of these is selection stage. The objective of this study was to obtain the information concerning the means and ranges of some quantitative characters, inbreeding depression, heritability estimates, and response to selection from six generations derived from crossing two parents of chili peppers. Materials used were IPB C160 (female), IPB C291 (male) as parents, F2, F3, F4, F5, and F6 derived from crossing of these parents with a total number of 630 plants. Results from this study showed that the mean valuesbetween the generations F2 to F6 showed an increase in the observed character except of harvesting time. The highest value of inbreeding depression for harvest time, weight per fruit, and fruit length was found in F5 generation. The highest value of inbreeding depression for fruit weight per plant, number of fruit per plant, and fruit weight was found in F6 generation, and for fruit diameter was found in F4 generation. The narrow-sense heritability estimates were classified into low to moderate criteria. In general, declined responses to selection for quantitative characters in the six generations of chili were observed.Keywords: advance selection, heritability, inbreeding depression, means value

Abstract

Breeding improved yardlong bean varieties is not only aimed for yield, but also for enhancing nutritional content such as anthocyanin and carotenoids concentrations. The objectives of this research were to elucidate the anthocyanin and carotenoids concentrations as well as yield components in several yard long bean genotypes. This research was conducted at the Leuwikopo Experimental Station and Post Harvest Laboratory of Department of Agronomy and Horticulture IPB from November 2017 to January 2018. The experiment was arranged in a single-factor randomized complete block design with 4 replicates, involving 15 yardlong bean genotypes. The results showed that Fagiola 2 had relatively high anthocyanin and carotenoids contents. Peleton had higher yield than Kinaya 1, Pangeran Anvi, Parade, and Fagiola 2. Anthocyanin content was not correlated with yield components, whereas carotenoids content was positively correlated with the length of pod stalks, length of pods, weight per pod, chlorophyll a, chlorophyll b, and total chlorophyll. Pod weights per plant were positively correlated with the number of pods per plant (r = 0.81, P<0.01), and can be predicted by a linear model involving number of pods per plant and days to harvest (R2 = 0.75, P<0.01).Keywords: biofortification, chlorophyll, correlation, stepwise regression, Vigna unguiculata var. sesquipedalis

Abstract

Okra fruit contains phenolic compounds as natural antioxidant. The aim of this research was to analyze the effect of different types of fertilizers on production and quality of two okra varieties. The experiment was conducted in October 2017 to February 2018 at Bogor Agricultural University experimental field at Leuwikopo, Darmaga, Bogor (-6033’49.3”SL, 106043’30.7’’EL). The experiment used nested randomized complete block design with 2 factors and 4 replications. The first factor consisted of two okra varieties with different colour (red and green okra). The second factor was fertilizer types consisted of no fertilizer, organic (cow manure), combination of organic + inorganic, and inorganic fertilizer. The results showed that fertilizer types significantly affected plant height and fruit N content but did not affect fruit production. Red okra had a higher plant height, lower number of leaves and leaf K content than those of the green okra. The interaction effect of both factors was significant on total phenolic content in fruit and P content in leaf. The highest total phenolic content in fruit was showed by red okra with inorganic fertilizer, although it was not significantly different to those of red okra with combination organic + inorganic fertilizer, and also to green okra with organic fertilizer. The highest P content in leaf was found in red okra without fertilizer, however it was not significantly different to red okra with combination organic + inorganic fertilizer, green okra with organic fertilizer, and green okra with inorganic fertilizer.Keywords: inorganic fertilizer, leaf nutrient, organic fertilizer, phenolic compound
