“…This suggests that the three pure lines L4, L8, and L9 outperformed in terms of production, whether in terms of number or weight; the slight differences among them can be attributed to differences in the average pod weight Fig 2 . It is also clear from what was previously shown that the three pure lines L8, L4 and L9 also excelled in the trait of the early yield, whether by weight or number. Similar results were obtained by Abo-El-Khar 2003, Masoud et al, 2007;Metwally et al, 2011;Ibrahim et al, 2013;Ibrahim et al, 2018 andHelmy andRagheb, 2019, who practiced inbreeding with selection to develop new strains of okra and stated that this method resulted in producing superior genotypes derived from Egyptian local cultivars.…”

This study aimed to improve the local okra cultivar (cv. Balady) by accessing superior earliness pure lines using an individual plant selection breeding program. Six cycles of individual plant selection were carried out at the Agricultural Experimental Station Farm at Abies region, Faculty of Agriculture, Alexandria University, Egypt, which resulted in ten pure lines with distinct horticultural traits. The selected pure lines were evaluated in the summer season of 2020 with the original population. The results showed that the pure lines L5 and L1 recorded significantly the lowest mean values compared to all the genotypes for the earliness traits, viz., days number to first flower and pod, as well as days number to 50% flowering, and days number to first harvest. Moreover, the selected pure lines significantly exceeded the original population in the characteristics of early and total yield per plant, and the three pure lines L4, L8, and L9 were the most distinguished for these traits. Concerning correlation estimates, the characteristics of earliness reflected positive and significant correlations between one another, as well as, with the characteristics plant height and early yield as the number of pods. The results of cluster analysis illustrated that the first group (I) was distinguished as being the earliest, while the third (III) and fourth (IV) clusters were the best for the productivity traits. So, it is recommended to use the pure lines L4, L8, and L9 to improve total and early yield as well as the earliness traits.

“…Selection is an appropriate method when wide variation is presented, particularly when the additive gene action is involved in the inheritance of the quantitative characters. Inbreeding with selection has been practiced to develop new strains of okra ( Masoud et al, 2007;Metwally et al, 2011). This method resulted in producing superior populations derived from local cultivars (Abo EL-Khar, 2003;Ibrahim et al, 2013) Inbreeding has been used in plant breeding programs to fix favorable genotypes of agricultural interest (Allard, 1999), to separate favorable genotypes (Singh, 2006), and to reduce the percentage of heterozygousity in the population (Falconer and Mackay, 1996).…”

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.

“…In other words, the selected pure lines of okra that bear the first flower or pod on a lower node will flower in fewer days than those bearing the first flower or pod on a higher node, and hence will flower earlier. In this regard, Jagan et al 2013;Metwally et al 2011;Vishnu Priyanka et al 2017;Vishnu Priyanka et al 2018 recorded similar results for nodes number to first flower character on okra genotypes.…”

This study was conducted during six cycles of an individual plant selection program to obtain promising pure lines of okra; that possess a new uniform architecture with desirable traits, using two local cultivars of okra, Balady and Eskandirani. This was followed by an evaluation of the selected pure lines with the two base populations. So, this study was conducted during the seven successive summer seasons of 2014 to 2020, at the Experimental Station Farm (at Abies) of the Faculty of Agriculture, Alexandria University, Egypt. The obtained results revealed that in the two original populations, the estimated means, ranges, and coefficients of variations of all analyzed characteristics exhibited noticeable variation in vegetative growth, productivity, and pod quality. Also, positive performance was obtained in the selected pure lines, where they were characterized by short to medium plant height, broad stem diameter, no branches (zero-type plants), and short internodes, as well as a low position of nodes number to the first flower or pod. Regarding productivity and quality of pods, the results showed that the selected pure line L 15 showed significantly the highest mean values for the characteristics of pods number per plant, pods yield per plant, pods yield per square meter. Also, the seven pure lines L 14 , L 10 , L 12 , L 9 , L 8 , L 11 , and L 13 recorded significantly higher mean values than the Eskandirani cultivar for the same traits mentioned earlier; while the five pure lines L 3 , L 4 , L 5 L 6 , and L 7 did not reflect any statistically significant differences from the Eskandirani cultivar.
