Abstract

This study aims to determine the pattern of segregation character soybean plant resistance to infection SMV and other agronomic characters as well as many genes that play a role in the inheritance of these traits in the F2 populations from crosses Taichung x Tanggamus follow of Mendel ratio or a modification of expectations and knowing the number of crosses. This research was conducted at the Laboratory LapanganTerpadu Faculty of Agriculture, University of Lampung from September 2013 until January 2014, and then continued in the laboratory observations Seed and Plant Breeding, University of Lampung. Propagation of virus carried in Kampung Baru, Bandar Lampung. This research uses experimental design without repetition with a single treatment design nested structured data is analyzed using the chi-square test for the suitability of the normal distribution and chi-squared test to test the of Mendel ratio and modifications . The results of this study indicate the character frequency distribution of plant height, grain weight per plant soybeans F2 generation from crosses Taichung x Tanggamus normal spread, while the frequency distribution for character flowering age, harvesting, healthy seed number per plant, number of productive branches, number of pods per plants and severity of disease spread is not normal. Estimates of the number of genes that control the character of harvesting is controlled by two genes are recessive epistasis duplicate the ratio 9: 7, days to flowering follow the ratio 1: 2: 1 which is controlled by a single gene that reacts not perfect, healthy character of the number of seeds per plant followed the ratio 3: 1 and for the total character of pods per plant, number of productive branches as well as the severity of the disease follows the ratio of 13: 3. the character dikendalikanolehdua genes dominant-recessive epistasis react. There are 21 numbers belonging expectations resistant to SMV. Keywords: Soybean, segregation, resistance characteristics, and SMV.

Abstract

The purpose of this study was to determine the amount of genetic diversity and phenotype, heritability in a broad sense as well as the numbers of soybean expectations F5 generation from crosses Wilis × B3570 which has a middle value the better of both parents. The experimental design used randomized group design by three replications. Genotypes were tested as much as 25 genotypes. he results showed that the amount of genetic diversity of soybean agronomic characters F5 generation from crosses Wilis x B3570 found in almost all the characters except the characters age observed flowering and harvesting age. The genotype diversity found in all agronomic characters were observed. The magnitude of the high heritability values found in the character of a weight of 100 grains. Heritability values were on plant height, number of productive branches, and the total number of pods. Character weight of seeds per plant, flowering age, and time of harvest had the lowest heritability. Numbers expectation obtained by the genotypes number 163-1-4, 130-2-11, 130-2-11, 163-1-15, 102-3-2, 163-1-1, 140-1-15 , 163-1-6, 181-5-4, 140-1-2 are rated according to the weight of the weight of seeds per plant that would refer to the high production Kata kunci: variability and heritability, and Soybean

Abstract

Penelitian ini bertujuan mengevaluasi keragaman karakter morfologi dan agronomi 13 populasi F 1 half-sibubi kayu di Bandar Lampung. Evaluasi dilaksanakan pada bulan Maret 2016 – Februari 2017. Populasihalf-sibmerupakan keturunan tetua betina Adira, CMM, CMM 25-27-43, CMM 25-27-46, CMM 25-27-143, CMM 25-27-158, CMM 97-6, Malang, Macan, T142, T12, T15 dan UJ5. Karakter morfologi dan agronomi meliputikarakter kualitatif dan kuantitatif. Keragaman karakter kualitatif luas jika persentase fenotipe rekombinan (PFR) > 67%, sedang jika 33%<PFR < 67% dan sempit jika PFR < 33%. Keragaman karakter kuantitatif dinyatakan luas jika kisaran total (range)> 2x Interquartile Range (IQR)dan sempit jika Range<2 x IQR. Karakter kualitatif tanaman ubi kayu meliputi warna daun pucuk, warna permukaan atas tangkai daun, dan warna permukaan bawah tangkai daun pada 13 populasi tersebut menunjukkan keragaman yang luas atau sedang kecuali warna permukaan atas tangkai daun pada populasi CMM 25-27-46 yang berkeragaman sempit. Karakter kuantitatif meliputi panjang lobus, lebar lobus, rasio panjang/lebar lobus, panjang tangkai daun dan rendemen pati menunjukkan keragaman yang luas pada populasihalf-sibCMM 25-27-43, CMM, Malang, T12, dan Macan. Populasihalf- sibAdira, CMM25-27-46, CMM 25-27-143, CMM 25-27-158, CMM 976, T15, T142 dan UJ5 menghasilkan keturunan dengan keragaman yang sempit dan luas.
