Selection is one of plant breeding techniques to obtain a desired character. The objective of this research was to determine information about the trait variance in F3 lines in terms of yield and yield components, knowing character could be improved through selection to obtain high yield lines. This study was conducted on june until august 2020 in the village Karang Bangun Rambung Merah Kecamatan Pematangsiantar, kabupaten Simalungun 500-550 with an elevation place, use augmented design. 20 × 30 cm plant distance, data observed for each individual plant, and done to find genetic variance, environment variance, phenotif variance, GCV, broad-sense heritability and Coefficient correlation. The result show that the value of heritability all character was moderate until high except the days of harvest was low. The value of GCV was narrow to the days to flowering and harvest, while other character value of the GCV was moderate until broad. Coefficient correlation indicated that Seed weight per plant was positively and significantly correlated with all studied traits except the days to flowering was negative and non-significant. Based on high heritability and broad GCV, selection process on seed weight per plant so 10 selected lines with highest seed weight.
