Abstract

Cajanus reticulatus var. grandifoProduction and characterization of hybrids between Cajanus cajan x C. reticulatus var. grandifoliuslius? endemic to Australia and a wild relative of the cultivated species, C. cajan, was successfully crossed with the latter as the female parent. The major wild species characters such as persistent stipules, long pod hairs, pod shattering, brown seeds with grey speckles, and presence of seed strophiole were dominant in the hybrid. For Production and characterization of hybrids between Cajanus cajan x C. reticulatus var. grandifoliusgrowth and branching habit, and leaflet, flower, pod, and seed size, the hybrid was intermediate between the parents. The raeiotic cells of the hybrid were found to have quadrivalents, trivalents, univalents, and showed reduced chromosome pairing as revealedProduction and characterization of hybrids between Cajanus cajan x C. reticulatus var. grandifolius by the increased number of rod bivalents per cell at metaphase-I, and stickiness and precocious movement of chromosomes to poles in the second division. In comparison to the parents, the hybrid had fewer pods and seeds. However, these anomalies in the interspecific hybrid are not significant-enough to preclude the gene transfer from C. reticulatus to the cultProduction and characterization of hybrids between Cajanus cajan x C. reticulatus var. grandifoliusivated species through a sexual route.
