A field experiment to obtain new improved soybean varieties with higher yield and seed size was conducted by crossing Slamet Variety (high yield, small seed size) with Nakhonsawan (large seed size) in order to produce F6 selected generation. The process of selection and evaluation was conducted during a 3.5 month period, from August to December 2003 in KP IPB Sindang Barang Bogor. The pedigree selection method was used in the experiments. Data was analyzed based on information of set of total data, relatives and individually. The results showed that low performance for all traits compared to the Slamet variety except seed size and seed production traits, and higher than Nakhonsawan variety except seed size. However, genetic variances and heritabilities were high for all traits except number of branch. On the other hand, distribution of genetic variances and heritabilities on all levels of relatives were small except for the within-family F6 generations. This indicated that there was an effect of over-dominance gene action. Conclusion of analysis showed existence of two families with high seed production and seed size if compared to Slamet variety. Key words: Soybean, selection, performance, genetic variability, and heritabilities.

Sweet potato is a food crop with high genetic and phenotypic diversities. The objective of this study was to cluster sweet potato clones based on their morphological characters. This research used descriptive method using 25 morphological characters on 28 sweet potato clones and clustered using dice coefficient, principal component analysis and biplot analysis. The results showed that the clones were grouped into two clusters and 14 sub-clusters. Three sub-clusters had high similarity coefficients, i.e., 0.68-0.96, one clone was eliminated, and 11 sub-clusters had a low similarity, i.e., 0.41-0.52. The principal component analysis showed 14 of 25 morphological characters determined the diversity in 27 sweet potato clones with cumulative variance of 70.79%. Biplot analysis showed that 12 characters contributed to cumulative variance of 61.3%. Twelve morphological characters had weak contribution on the characteristics of the clones in quadrant I; meanwhile, characteristics of clones in quadrant II were orange, yellow and white tuber flesh, in quadrant III was dark purple tuber flesh, and in quadrant IV were purple tuber flesh and cortex. Result of the grouping analysis identified clones that were closely related and those distantly related for improvement purposes.Keywords: Ipomoea batatas, cumulative variance, Maluku province, morphology, relationship

Kacang hijau (Vigna radiata L. Wilczek) merupakan salah satu tanaman Leguminosae yang cukup penting di Indonesia. Permasalahan yang sering muncul pada budidaya kacang hijau adalah tidak serempaknya panen sehingga membutuhkan waktu dan tenaga kerja yang lebih banyak. Tujuan penelitian ini adalah untuk mengevaluasi karakter agronomi 10 genotipe lokal kacang hijau dan menganalisis jarak genetik antar genotipe-genotipe tersebut berdasarkan karakter kuantitatif dan kualitatif. Percobaan dilaksanakan di Kebun Percobaan IPB Leuwikopo Dramaga, Bogor pada bulan April hingga Agustus 2013, dalam rancangan acak kelompok (RAK) dengan faktor tunggal yang terdiri atas 10 genotipe kacang hijau lokal dan satu varietas nasional sebagai pembanding dengan tiga ulangan. Hasil penelitian menunjukkan bahwa genotipe-genotipe yang diuji berbeda nyata dengan pembanding pada komponen pertumbuhan, komponen umur tanaman, dan komponen produksi. Genotipe LL3 merupakan genotipe dengan keragaan terbaik (berdasarkan parameter: komponen produksi, komponen umur tanaman, dan komponen keserempakan panen), diikuti LL4, LWL, dan LKH. Berdasarkan analisis jarak genetik, genotipe-genotipe yang diuji mengelompok menjadi empat kelompok (berdasarkan karakter kuantitatif) dan tiga kelompok (berdasarkan karakter kualitatif).

Diallel analysis of multiple traits is a comprehensive approach to evaluate general combining ability (gca), specific combining ability (sca) and reciprocal effects of parents and it crosses by involving many traits simultaneously. Describing of cross-by-traits biplot (CT Biplot) can be used to describe the multiple traits diallel analysis. In order to improve the yield potential, four parents of the local varieties and two parents of the high yielding varieties of mungbean were evaluated their multiple traits combining ability by using Griffing Methods I. Results of the research show, there are 3 meaning sectors (MS) and 2 non-meaning sectors (NMS) of crosses and multiple traits. The parents Lasafu Lere Butsiw (LLBs) and Gelatik contained high gca in one MS which associated with traits of the grain weight, number of seeds per pod, number of seeds, number of filled seeds, number of pods, and number of filled pods (MS-1). The parents Lasafu Lere Butsiw fer Namamas (LLBfN), Lasafu Lere Butnem (LLBn), and variety No. 129 in the next MS (MS-3) related to the 100 seed weight trait, meanwhile the parent Mamasa Lere Butnem (MLB) located in another NMS, contained high gca for an ideal type of short plant. Crosses combination of Gelatik × LLBs, Gelatik × LLBfN, and MLB × LLBn were vertex crosses on MS-1 and therefore, having high sca for the traits that mutually-correlated in the sector. In the other two MS sectors, the parents LLBn and LLBs were vertex genotype, so that crosses that have best sca were not found. Reciprocal effects can be viewed in some crosses, which LLBs × Gelatik was the cross combination with the highest reciprocal effects.

Genetic diversity is required for crop improvement against environmental stress. Astudy wasconducted to determine characters as selection indicators of water-stress tolerance, and of yield components and yield. The research method involved a one-factor experiment with 21 sweet potato clones, using a Completely Randomized Block design with three replicates. Water stress in this study mean that the bottom of plants was submerged in water at 2 and 3 months of age. Determination of selection indicators was conducted by estimating the coefficients of genetic and phenotypic variations, heritabilities, genetic advance and correlation test result. The characters of number of leaves, individual leaf area, leaf area per plant, leaf area index, stem length, internode length, number of tubers (storage root), individual tuber weight and yieldas selection indicators of water stress tolerance. Selection indicators of yield components consisted of less number of leaves, small leaf size, short stemsand number of branches, whereas selection indicators of yield were small leaf size, number of branches, number of tubers and individual tuber weight. Selection became effective and efficient when the selection indicators were influenced greatly by genetic factors.
