GENETIC VARIATION AND HERITABILITY STUDIES IN SOME OKRA (ABELMOSCHUS SPP) VARIETIES

G. G. Jibung, W. Manggoel

Abstract


A study on Genetic variation and heritability estimates in 52 okra varieties was conducted at the Teaching and Research Farm, Federal University of Agriculture, Makurdi (07o 41’N, 08o 37’E, 106.4m asl). The aim of the study was to assess the level of genetic divergence and heritability of quantitative traits of some okra varieties in 2018 rainy season in a randomized complete block design (RCBD) with three replicates. Data recorded on thirteen quantitative traits included plant height (PH), number of branches/plant (NB/P), number of leaves/plant (NL/P), days to flowering (DFF), days to 50% flowering (D50%F), days to harvestable pods (DHP), number of pods/plant (NP/P), pod length (PL), pod girth (PG), pod weight (PW), number of seeds/pod (NS/P), hundred seed weight (100SW) and pod yield/plant (PY/P). The result showed significant differences (p<0.05) in all the traits studied. Wide range of variability were recorded for PY/P (88.33 – 774g), followed by PH (64.00 – 242.00cm), DFF (42.00 – 109 days) and D50%F (45.00 – 112 days). Broad sense heritability (Hbs) ranged from moderate (54.00%) in 100SW (g) to very high value (100.00%) in PH (cm).
