Abstract

                                The Inter-subspecific crosses involving Spanish x Virginia genotypes exhibited greater magnitude of heterobeltiosis for pod yield, pod number, pod and kernel weights than the intra- subspecific crosses. The intra-subspecific crosses were superior for plant height. Negative heterosis was observed for shelling percentage in both the types of crosses.
