摘要

Interspecific hybridization is an attempt to allow transfer of useful genes from related wild species to cultivated types and to understand species affinities based on genetic and chromosomal studies, plant morphology, crossability, meiotic behaviourand seed protein profiles etc. Present study is an attempt to evaluate the potential value of wild species of pigeonpea as one of the parents in interspecific hybridization for utilizing existing genetic variability, identification of known and unknown traits of importance such as resistance to diseases and pests and superior nutritional qualities as preliminary requirement in an interspecific hybridization programme. This study has identified four wild species namely C. acutifolius, C. goensis, C mollis and C. platycarpus based on characterization and preliminary evaluation of 13 wild species for some vegetative, floral and fruit characters. Wild species of pigeonpea were obtained from ICRISAT, Patancheru. These four species of pigeonpea flowered andhad set pods and seeds at IARI, New Delhi. Some information is already reported in these four wild species (Table 1) (Nene et al., 1990).
