Genetics of Fruit Quality in Okra (Abelmoschus Esculentus) under Waste Water

A field experiment consists of five genotypes of okra was conducted in the research area of the Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad during crop season 2010-2011.All possible crosses were made to obtain F1seed following diallel analysis design. The F1 seed along with their parents was evaluated. The experiment was laid out in randomized complete block design. Data was collected for some quality traits as protein content, dietryfiber content and carbohydrates. The numerical approaches demonstrated that dietary fiber contents and carbohydrate contents under wastewater irrigation were ruled by over-dominance with non-additive type of gene action while partial dominance was observed in protein contents under wastewater irrigation, dietary fiber contents and carbohydrates under normal irrigation water which suggested that early selection might end up in improving these genotypes. Non-allelic interaction or epistasis was absent for all the traits studied. It indicated thatselection in early generations for these traits would be difficult.
