Abstract

Selection of the population F3 and F4 by method single seed descent was to obtain information about the genetic diversity character agronomy and yield components. The experiment was conducted at experimental field of the Agency for Biotechnology and Genetic Resource, Bogor start October 2012 to May 2013. The genetic material were F3 and F4 population derived from single seed descent. The result showed that mean of the population F4 higher than the population F3 to all characters. Components variability of phenotype, environment and genetic population F4 higher of the population F3 for almost all the characters except number of branches and 100 seed weight characters. The heritability estimates for population F3 and F4 were classified as moderate to high. The heritability estimates for population F3 only 100 seeds weight character were classified as moderate, while the heritability estimates for population F4 character of number of vacuum pods, seeds weight per plant, 100 seeds weight and sink size were classified as moderate. The genetic diversity coefficient for population F3 and F4 character of number of branches, number of vacuum pods, seeds weight per plant, and 100 seed weight were classified as narrow, while the genetic diversity coefficient for character of plant height, number of book, total number of pods, number of pithy pods and sink size were classified as broad.
