Abstract:
This study was intended to determine variability, genetic variance component, and heritability of several agronomic characters in a population consisting of eight soybean genotypes. A field experiment had been conducted in the experimental station of Faculty of Agriculture, University of Riau from July 2012 to October 2012. The eight genotypes was planted in the field experiment and arranged in randomized block design with three replications. The genotypes were Malabar, Willis, Kipas Putih, KM-11 AB, KM-13 ED, KM-14 DD, KM-19 BE, and KM-25 EC. Traits observed were plant height, time to flowering,time to harvest, 100-grain weight, grain yield m-2, oil content and protein content in the seed. Result indicated significant genetic variability for plant height,time to harvest, 100-grain weight, grain yield m-2, oil content and protein content in the seed, but not for time to flowering, filled pod percentage, and seed weight per plant. Heritability ranging from o.25 to 0.94 being significantly different from zero for plant height, time to harvest, 100-grain weight, yield m-2, oil and protein content in the seed but not for time to flowering,filled pod percentage, and seed weight per plant.
