Title

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.

ABSTRAKPerbaikan hasil kacang hijau dapat dilakukan melalui seleksi langsung maupun seleksi tak langsung berdasarkankriteria seleksi dari satu atau beberapa sifat kuantitatif sebagai indikator seleksi. Penelitian ini bertujuan untuk memilihindikator seleksi bagi hasil biji dan menentukan kriteria seleksi bagi indikator seleksi tersebut pada populasi generasi awalkacang hijau berumur genjah. Penelitian menggunakan rancangan acak tak lengkap berblok bersekat-tersarang 1-tahap.Analisis lintas dan regresi aditif serta genotipik masing-masing digunakan untuk memilih dan menentukan indikator seleksi dan kriteria seleksi. Hasil analisis pengaruh langsung memperlihatkan jumlah biji bernas dan umur berbunga merupakanindikator seleksi bagi hasil biji dengan kriteria seleksi 200 biji pada kisaran umur berbunga 40-46 hari, untuk memperolehhasil > 12 g tanaman. Sebaliknya, hasil analisis pengaruh tak langsung memperlihatkan tinggi tanaman, jumlah cabangdan lama hari panen dapat pula dimasukkan sebagai indikator seleksi. Kriteria seleksi bagi masing-masing indikator seleksiini adalah dua cabang dengan lama hari panen 16-20 hari dan tinggi tanaman sekitar 85 cm untuk menghasilkan 200 biji.Bila dipilih tanaman yang lebih pendek, kriteria seleksi tinggi tanaman 75-80 cm dapat digunakan, namun lama hari panenmenjadi 22-26 hari.-1Kata kunci: analisis regresi, analisis lintas, BLUP, seleksi generasi awal

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
