Abstract

                                One way compatibility between the species of Capsicum viz. Copsicum annuum and Capsicum frutescens was realised. In spite of occurrence of post-fertilization barriers, hybrids could be grown to maturity in respect of some combinations of parents only. High sterility bath genic and chromosomal in origin was evidenced. The differentiation between the parental species seems to rest upon genic or small structural differences in their chromosome components. The cytological behaviour of the hybrids points to the non development of genic mechanisms which inhibit pairing of chromosomes in the Fis
