Genetic parameters in okra

Environmental factors induce several interactions in okra (Abelmoschus esculentus (L.) Moench), resulting in plant modifications both on the vegetative and reproductive phase. Environment can also cause variation in values of some genetic parameters. In order to estimate the genetic variability and...
