“…Similarly, ploidy level was also not reported to affect crossability as crosses were obtained successfully between diploid × tetraploid ( V. radiata × V. glabrescens ) (Chen et al 1989 ;Krishnan and De 1968 ) and tetraploid × diploid ( V. glabrescens × V. umbellata ) Vigna species. Postfertilization barriers of varying degrees have also been reported in most of the interspecifi c Vigna crosses (Dana 1964 ;Biswas and Dana 1975 ;Machado et al 1982 ;Chen et al 1983 ;Al-Yasiri and Coyne 1966 ;Bharathi et al 2006 ;Pandiyan et al 2010 ;Chaisan et al 2013 ). These affect the successful recovery of desirable recombinants through development of shriveled hybrid seed with reduced or no germination (hybrid inviability), development of dwarf and non-vigorous plants and death of F 1 plants at critical stages of development (hybrid lethality).…”

“…Barone et al ( 1992 ) observed that the embryos and endosperm in the cross between V. vexillata and V. unguiculata degenerated within 5-8 days after pollination. Using embryo rescue, successful crossing could be accomplished in V. mungo × V. umbellata (Biswas and Dana 1975 ;Chen et al 1983 ). Singh et al ( 2003 ) also produced successful hybrids between V. radiata and V. umbellata , and the hybrids possessed intermediate morphology with MYMV resistance.…”

Alien Gene Transfer in Crop Plants, Volume 2

The genus Vigna comprises more than 200 species of which 7 are of tremendous agronomic importance. These are grown mainly in the warm temperate and tropical regions of the world. Valued for their grains with high and easily digestible proteins, these crops are also known as forage, green manure, and cover crops. Due to a short life cycle, these are suitable as catch crops and also fi t well in intercropping, mixed or relay cropping. For genetic improvement of cultivated vignas, mainly cultivated germplasm and exotic lines have been used so far. However, despite development of several improved cultivars in different Vigna crops, biotic and abiotic stresses still remain the major constraints in realizing their true yield potential. While plethora of genes conferring resistance/tolerance to these stresses have already been transferred from cultivated germplasm, wild genetic resources offer additional sources of useful alien variation which can be incorporated in cultivated Vigna through alien gene transfer. With better understanding of the processes behind pollen germination and pollen tube growth, fertilization, embryo and endosperm development and inheritance pattern, strategies have been developed to avoid pre-and post-fertilization barriers in successful distant hybridization leading to alien gene transfer. These include making reciprocal crosses, repeated pollination, hormonal treatment of fl ower buds, polyploidization, use of bridge species and most importantly, embryo rescue which have increased success rate of alien gene transfer in Vigna through sexual hybridization. Nevertheless, alien gene transfer through genetic transformation and use of molecular breeding tools still lag behind in Vigna and therefore need special attention. The signifi cant achievements made in different Vigna species in alien gene transfer and their utilization have been discussed in this chapter.

A total of 80 interspecific crosses i.e., 36 each of V. radiata × V. umbellata (V. radiata as female) and V. mungo × V. umbellata (V. mungo as female) and 08 crosses of V. radiata × V. mungo (V. radiata as female) were attempted to study the crossability relationship among these three Vigna species. Among the crosses of V. radiata × V. umbellata the crossability was observed highest in HUM 12 × RBL 9 (16.27%) followed by HUM 12 × RBL 9 (15.78%). In case of V. mungo × V. umbellata, the maximum crossability of 11.36% was noticed in cross, Mash 338 × RBL 9. For V. radiata × V. mungo, the highest crossability was visualized in hybrid, ML 1464 × Mash 338 (37.5%). The study indicated that different kinds of pre and post fertilization barriers are responsible for complete sterility to low fertility. RBL 1 and RBL 9 gnotypes of ricebean showing substantially high percent of crossability and better seed set with different cultivars of mungbean and blackgram may be utilized for genetic improvement of the mungbean and blackgram.

“…Prevention of fertilization, F, hybrid inviabilobtaining a hybrid, the degree of sterility among ity or sterility, and inviability or weakness among hybrids, or the agronomic worth of backcross, F, or later generations may be influenced by the genotype of individual plants or lines used as parents (Hadley & Openshaw, 1980) . Interspecific hybrids between Cucumis zeyheri and C. sativus (Custers & Den Nijs, 1986), Nicotiana repanda and N. tabacum (Pittarelli & Stavely, 1975), Trifolium nigrescens and T. repens (Hoven, 1962), Vigna radiata and V. umbellata (Chen et al ., 1983) . and Zinnia angustifolia and Z. elegans (Boyle et al ., 1987) have been obtained by identification and utilization of parental lines or clones which significantly improved crossability .…”
