Fruit characterization study is very useful for genotype improvement and genotype classifi  cation of papaya. In this study the morphological characters of 36 genotypes were analyzed to determine their phenotypic variabilities.  The relationships between genotypes based on all of the morphological and fruit characteristics were tested by subjecting the data to multivariate principal component analysis and to cluster analysis. Based on the dendrogram generated from vegetative and generative characters, the 36 genotypes could be grouped into 11 clusters on a threshold of 1.6 and formed 6 clusters on a threshold of 1.8.  The dendrogram was able to explain the close relationship between IPB 5 x IPB 1 and IPB 5 x IPB 4, IPB 2 and IPB 7, IPB 1 and IPB 3 genotype. The scattered diagram of generative variable divided the papaya genotypes into three groups based on fruit sizes i.e small group (IPB 1, IPB 3, IPB 4, IPB 3 x IPB 4, IPB 1 x IPB 9), medium group (IPB 5, IPB 7, IPB 8, IPB 9) and big group (IPB 2, IPB 10).  The IPB 1, IPB 3 and IPB 4 were different from IPB 2 in fruit shapes, petal length of male fl  owers, infl orescence size and fruit length. The hybrid plants obtained from crossings with IPB 10 were different from the other genotypes in the colours of female-, hermaphrodite-, and male fl  ower-lobes. Subsequently the scatter diagrams also revealed that several genotypes i.e. IPB 2 x IPB 6, IPB 1 x IPB 5,  IPB 1 x IPB 9, IPB 5 x IPB 1 and IPB 5 x IPB 2 had superior characters  ideotype similar to IPB 1, IPB 3 and IPB 8 genotypes.

Abstract

Anther culture provides rapid route in obtaining pure lines in a single generation through producing green haploid plants that may be spontaneously doubled. This technique has been used for crop improvement especially in rice. The objective of this research was to determine regeneration ability of eight F1s derived from crossess between upland and new plant types of rice and from their four parents through anther culture. Completely randomized design with 25 replications was used in this research. Treatments consisted of four parent lines/varieties i.e. P1 (Fatmawati and BP360E-MR-79-2), P2 (Fulan Telo Gawa and Fulan Telo Mihat) and eight F1s obtained from reciprocal crosses of P1 and P2. Callus induction medium was based on N6 medium + 2.0 mg L-1 NAA + 0.5 mg L-1  kinetin + 10-3  M Putrescine, while regeneration medium was based on MS + 0.5 mg L-1  NAA + 2.0 mg L-1  kinetin + 10-3  M Putrescine. The result indicated that F1 derived from Fatmawati x Fulan Telo Gawa (5.00% green plants per total anther) and their reciprocal (3.80% green plants per total anther) crosses were the most responsive genotypes in rice anther culture (had high anther culture ability). The F1 genotypes were more effective to produce green and doubled haploid plants in rice anther culture than their parents. From this research, 161 double haploid plants (29.81%) from total acclimated green plantlets were obtained.  Keywords: anther culture, upland rice, new plant type of rice

Abstract

Extension of jatropha planting on coastal sandy soil is an effort to look for an alternatif area to other soil types, this experiment is one of a series experiment aiming to classify jatropha based on their drought resistance, and to determine watering interval causing drought stress. The experiment was arranged using Split Plot Design with watering interval (once in 1, 3, 5, 7, and 9 day (s)) as main plot, and jatropha genotypes (IP-1A, IP-1M, IP-1P, IP-2A, IP-2M, IP-2P, Unggul Lokal (NTB), Gundul and Daun Kuning) as sub plot. The seeds of genotypes were planted in black polybag with coastal sandy soil media. The parameters observed were plant height, stem diameter, number of leaf, leaf width and plant dry weight, and the data collected were analyzed using Analysis of Variance, DMRT, Regrression and Cluster Analysis. The result showed that IP-1A, IP-2M, Gundul and IP-1M are the resistant genotypes, whereas Unggul Lokal, Daun Kuning, IP-2A and IP-2P are the susceptible genotypes. Once in one and three day (s) are optimum watering intervals, and once in nine days is a watering interval causing drought stress. Keywords : jatropha, drought, watering, coastal sandy soil

It was arranged in factorial randomized completely design with three replication. The fi  rst factor was cocoa clones i.e. ICCRI 01, ICCRI 02, ICCRI 03, ICCRI 04, KW 514, RCC72, and Sca 6. The second factor was fl  ower parts i.e. petal, staminode and anther. Every explant was regenerated on initiation, induction, multiplication and rooting media. Almost all treatments showed high response of embryogenic calli which range 89.5 to 100% at initial stage, but different results were found at the following process of somatic embryogenesis. The experiment showed that each clones and each different part of fl  ower had different response to somatic embryogenesis. The highest response of the explant number resulted from Sca 6 clone, which produce 35.8% embryo with average number of embryo per explant (1.34) followed by RCC 72 (28.4%, averaged 0.7) ICCRI 03 (24.7%, averaged 1.3) ICCRI 04 (18.6%, averaged 0.6). While ICCRI 02 showed the lowest responsive clone. Especially for ICCRI 01, 55.8% explant was rooted and  only 1.3% explant producing embryo. The highest response of somatic embryo was resulted form petal. Keywords: somatic embryogenesis, fl ower explant, Cocoa

The research objective was to study the dry matter distribution pattern of several peanut cultivars. Twenty cultivars were planted at two different locations, Cikarawang and Sawah Baru Experimental Field but at the same elevation (250 m above sea level). The cultivars were scored according to morphological and physiological characters, total N and total non-structural carbohydrates (TNC), yield and yield components.  There were no statistically differences in pod yield, seed yield and harvest index between the cultivars, but there were differences in dry matter distribution between cultivars. TNC content in stem correlated positively with pod fi  lling. Carbohydrates for pod fi  lling presumed were derived from dry matter accumulation in early pod fi  lling stage. It was concluded that the ideal growing type of peanut are early accumulated dry matter but almost no increase of dry matter accumulation in upper part of plant during seed development.

Since sorghum is not a native species of Indonesia, the genetic variability of this crop in Indonesia is low, thus, plant breeding program is required to support national sorghum development. The objectives of this study were  to  develop superior genotypes to improve sorghum production and quality for food, animal feed and bioethanol industry. Sorghum production is aimed at optimal use of unproductive or marginal land such as that of drought prone areas. Sorghum breeding  through induced mutations was conducted at Center for the Application of Isotope and Radiation Technology, National Nuclear Energy Agency (BATAN). Durra variety was used as parental materials in the breeding program. Induced mutation was made by gamma irradiation on seed treatments. The optimal radiation dose was found to be between 300-500 Gy. Through selection processes and direct screening for drought tolerance in Gunung Kidul district,  ten putative mutant lines had been selected.  In  dry  season,  the mutant  lines  B-68,  B-72,  B-95  and  B-100 produced grain yields of 4.55, 4.50, 4.20 and 4.62 ton ha-1, respectively. These yields were signifi  cantly higher than the original parent Durra (3.50 ton ha-1) and the control check varieties UPCA (2.68 ton ha-1) and Higari (3.75 ton ha-1). The mutant lines B-68, B-72, B-94, and B-100 were drought tolerant genotypes having a relatively higher drought index. These mutant lines were promising for further sorghum breeding and development in accordance with attempts of increasing land productivity of drought prone areas. Sorghum cultivation in such areas would promote land conservation and support sustainable agriculture development in the region. Keywords: drought tolerance, induced mutation, mutant lines, sorghum
