dc.descriptionThis study aimed to estimate the heterosis, heterobeltiosis, and inbreeding depression in grain sorghum hybrids. Twenty-five hybrids were evaluated in two seasons. The evaluated traits were days to flowering (FL), plant height (PH), grain yield (GY), and thousand grains mass (M1000). The contrast tested were F1 hybrids vs. check cultivars, F1 hybrids vs. parental lines, and F1 hybrids vs. F2 hybrids. The hybrids 1167048, 1099044, 1170017, and 1169054 had a five-day less flowering time than their parental lines. The hybrid 1170017 had a high grain yield (6.23 t ha-1) with 43.55% of heterobeltiosis. The diversity between lines was narrow. However, hybrids with higher grain yield, heterosis, and heterobeltiosis showed higher genetic distances from their parental lines. The inbreeding depression between F1 vs. F2 was 30%, indicating that using F1 hybrids seeds is worthwhile.
