Abstract

This investigation aimed to genetic improvement of local okra (cv. Balady) plants and to develop superior inbreds through selection and inbreeding. Three cycles of selection were employed in three consecutive seasons of 2013, 2014, 2015 and the developed inbreds were evaluated in summer season of 2016 with the local variety. The analysis of variance parameters showed a great variation for all studied traits within the cv. Balady. Therefore, the selection and inbreeding procedure resulted in isolation of twelve inbreds characterized by different horticultural traits. These inbreds showed uniform plants within each genotype. Highly significant variations were obtained for all the studied traits. On the basis of mean performance, the results of evaluation trial showed that the inbreds L5 and L8 were the earliest in flowering time. The selected inbreds L3, L6 and and L10 significantly exhibited the largest means of plant height. The developed inbreds significantly exceeded the cv. Balady for yield/plant and total yield, except for L8, L9 and L11. The selected inbreds L5 and L8 exhibited the largest means of pod length and pod weight and they surpassed the Balady pod measurements. The magnitudes of genetic variation were close to the magnitudes of phenotypic variation for all traits, indicating that the predomination of genetic component in the expression of the studied traits. There are positive and significant correlations between yield/plant and plant height, number of pods/plant and total yield/fed which prove the relative importance of the foregoing traits for yield improvement through selection of these traits. It is recommended to use the L3, L10, L4 and L7 inbreds for maximizing yield production Therefore, the foregoing inbreds are considered as promising genotypes suitable for growing under local environmental conditions.
