Abstract

Okra (Abelmoschus esculenthus L.) is a functional food crop consumed when the pod is immature and tender. Crosses the local okra, i.e. green and red okra, with introduced varieties B291 and Ve022 aimed to improve the local cultivar traits. This study aimed to assess the agronomic variability of S2 from a cross between green okra and red okra with introduced varieties and select superior families that can be used to produce new cultivars. The study used an experimental method with individual observation. There were 12 S2 families evaluated in this study. There were 12 S2 families evaluated in this study, derived from selfed-pollinated plants of the S1 families. Results showed that all S2 okra plants had tender fruit at 8 DAA, 56.3% and 7.8% of the entire population had tender fruit at 9 and 10 DAA, respectively. The increase in the fruit picking time was in line with the increase in size and weight of okra fruit. Variations in quantitative traits were observed, including flowering time, plant height, and the number of flowers and fruits in the S2 families. The performance of qualitative traits of the S2 families was uniform. There was a decrease in the quantitative trait of S2 families compared to the S1, which the inbreeding depression might cause. FOHVE022-17.4.8, FOHB291-15.7.20, SOMB291-24.18.1 and SOMVE022-10.1.8 families can be continued for further evaluation because they have a good quantitative trait performance.
