Heritability of agronomic characters of Srikandi Putih x local waxy corn

Abstract

High-protein corn and glutinous already exist, but the unification of these two traits is still temporary we did in a study. The effort to unite the properties of high protein and glutinous (high amylopectin) was started from hybridization between Srikandi Putih Variety corn and Local Waxy Corn followed by a series of crosses and selection. The continuity of a selection in breeding requires the value of heritability as a foundation. The purpose of this study was to determine the level of breeding progress in the corn assembly program with high amylopectin and protein levels based on heritability values. This study was designed in the form of a randomized block design. The treatments are varieties or genotypes which consist of 5 types: G1 = Srikandi Putih (parent 1♀); G2 = Local Waxy Corn (parent 2♂); G3 = F1; G4 = F2 and G5 = F3, repeated 3 times. Data for each parameter were analyzed for variance and heritability values. The results showed of Broad-Sense (BS) and Narrow-Sense (NS) heritability of the plant’s height 0.75 (BS), 0.61 (NS), number of leaves 0.71 (BS), 0.55 (NS), flowering age ♂ 0.78 (BS), 0.52 (NS), and flowering age ♀ 0.79 (BS), 0.64 (NS), ear length 0.72 (BS), 0.56 (NS), ear diameter 0.77 (BS), 0.54 (NS), weight of 100 seeds 0.73 (BS), 0.60 (NS), seed production per hectare 0.78 (BS), 0.58 (NS), protein content 0.53 (BS), 0.51 (NS), amylopectin content 0.60 (BS), 0.52 (NS). The heritability values of all measured properties parameters are generally included in the rather high category.
