Abstract:

Objective of the research was to obtain information on the heritability estimation in resistant soybean toward CPMMV to determine the method of selection on seeds quality. The research was conducted at Mlilir Village in Madiun from August to December 2012 at the altitude of 115 m asl. This study used Complete Randomized Design by three replications. Population of female parents is Argopuro and Gumitir as the susceptible parents, MLG 0278 and MLG 0120 as the resistant parents. Whereas, population F1, population BC.1.1 and BC1.2 comprises of 30 plants and population F2 comprises of 300 plants. CPMMV inoculation was mechanically conducted at the age of 10 days after planting. Observed parameters include: plant height, number of branch, age of flowering, number of filled pod, number of empty pod, number of fertile node, age of harvesting, seed’s weight per plant, and intensity of disease infection. Parameter of CPMMV infection intensity was assessed at the age of 35 days after inoculation (45 days after planting). Results of the research showed that parameter of the infection intensity has high value of broad sense heritability and low value of narrow sense heritability for all crossbred series, thus we suggested for further research to apply bulk selection method.
