Abstract
The possibility of testing mungbean for grain yield in monoculture in single wide-spaced row plots as an alternative to selection in intercropping with maize was investigated. Results indicated no significant genotype x planting pattern interactions and genetic correlation coefficients between grain yields in the two planting patterns were, in most cases, close to unity. It was concluded that, as far as the mungbean component in the mixture is concerned, yield selection in either of the two planting patterns is justified. Effects of single-plant and progeny selection on mungbean characteristics were also studied empirically. Lines derived from single-plant selection in monocropping or intercropping showed differences in yield, number of pods per plant and seed weight. Except for seed weight, no differential effects of progeny selection in monoculture or intercropping were observed for any characteristic.
