| Abstract | ||
| This investigation was carried out at the Sabahyia Horticultural Research Station, Alexandria, during 2004 and 2005 summer seasons, Plant materials of this study consisted of eight ecotypes of moloukhyia, which were collected from different regions of Egypt in addition to eskandarany variety. Siwi ecotype gave the highest mean values of plant weight, leaves weight 1 plant, number of leaves I plant. and seed yieldiplant. The balady sohag ecotype recorded the largest number of branches! plant. The largest number of seeds I pod was obtained by the balady sharkeia ecotype. Balady sohag ecotype recorded the largest fresh leafy yieldlfed. Concerning the later trait, balady sohag ecotype did not significantly different between siwi and saidy sohag ecotypes in the first cut, and eskandarany variety in the second cut, while eskandarany variety and fallahy sharkeia and saidy sohag ecotypes were not significantly different in the total leafy yield. The results revealed significant differences among moloukhyia genotypes for all studied traits indicating wide genetic variation. Broad—sense heritability was high in all studied characters. Plant weight, net leaves weight, plant height, number of seeds lpod, and number of podslplant may be improved by selecting the top 5% of the studied genotypes, because they had the highest values of heritability, which were associated with high values of genetic coefficient of variability and genetic advance. Pathecoefficient analysis indicated that number of podsfplant had a clear positive direct path, followed by plant height. As the correlation coefficient between both of number of brancheslplant and number of seedsi‘pod with seed yield was positive and the direct effect of this factor was negligible, it seems that indirect effect appeared to be the cause of correlation. Hence, these factors may be used, simultaneously, with plant height, and number of pods, in improving seed yield in moloukhyia. | ||
