Morphological studies on interspecific hybrids between Citrullus lanatus L. and its wild species
Author(s): J Jamatia, H Choudhary and B Basavaraj
Abstract: The present investigation was carried out to obtain interspecific crosses in genus Citrullus involving two wild relatives of C. lanatus var. citroides (DWM 32 & DWM 35) (diploid, 2n = 22), a wild perennial C. colocynthis and Sugar Baby (diploid, 2n =22). The genotypes DWM 32, DWM 35 and DWM 210 used as male parents and Sugar Baby as female parent. The interspecific crosses yield three hybrids. The F1 progeny resembles mostly with C. colocynthis for many characters like perennial growth habit, leaf colour and leaf lobing, flower colour, and bitter spongy pulp of fruit and bitterness of flesh as well as seeds. Some characters like fruit shape and rind pattern on ripening, shape and colour of seeds resembled to that of cultivated type Sugar Baby. The fruit size, seed size and flesh colour were found to be somewhat intermediate between C. colocynthis, C. lanatus var. citroides and C. lanatus var. lanatus. There is variation in the expression of three different F1 progenies from wild relatives in response to WBNV. The main aim is to transfer resistance traits from wild into cultivated for future crop improvement studies.
