“…4). The results are in agreement with the findings of Bindra et al, (2020), they reported germination percentage upto 59.34 % in V. mungo x V. umbellata hybridization whereas, Basavaraja et al, (2018) found germination percentage of 36.84 % in interspecific crosses between V. radiata & V. umbellata, Lekhi et al, (2017) noted germination percentage upto 30.56 % in interspecific crosses of urdbean and mungbean. Some of the F 1 seeds did not imbibe, some showed distorted cotyledons, poor root development whereas in some cases roots developed but died before shoot formation so success rate in germination was low.…”

Interspecific hybridization was performed between five genotypes of urdbean & three genotypes of mungbean to check the crossability relationship. Thirteen cross combinations of urdbean x mungbean were successfully developed. Interspecific seeds showed no germination under soil conditions so various growth media were used for germination. Interspecific seeds germinated only on the salt solution. F1 seeds of cross UG-218 x Suketi exhibited highest crossability and showed maximum response on salt solution. The study put emphasis on the different kinds of fertilization barriers. In future genetic improvement studies can be carried out with the genotypes showing substantially high percent of crossability.

“…Therefore, pre-breeding practices such as interspecific hybridization are required involving particularly those wild species that carry useful alien gene(s) for improving the crop (Pratap et al 2021). The related underutilized species V. umbellata (Ricebean) and V. angularis (Adzukibean) have been found to be nutritive and resistant to most of the fungal pathogens of urdbean, giving a window to breeders to broaden the narrowed genetic base of the crop (Bindra et al 2020). But the crossability of these Vigna species with urdbean is very low due the presence of pre-and post-fertilization barriers.…”

Cercospora leaf spots is one of the major foliar diseases of urdbean (Vigna mungo (L.) Hepper) causing a considerable yield loss. Screening of germplasm and induction of mutation has not yielded any source of resistance. Hence, an experiment was conducted at research farm of CSKHPKV Palampur, Himachal Pradesh during 2017–21 for introgression of disease resistance in urdbean. A total of 45 interspecific cross combinations were attempted between urdbean × moongbean [Vigna radiata (L.) R. Wilczek], urdbean × ricebean [Vigna umbellata (Thunb.) Ohwi and H. Ohashi] and urdbean × adzukibean [Vigna angularis (Willd.) Ohwi and H. Ohashi]. Only 12 interspecific crosses were successful. SSRs were used for confirmation of hybridity of the wide crosses. True F1’s were phenotyped for 13 morphological characteristics with respect to parental lines to study the trait expression. Most of the morphological characteristics of the interspecific F1’s were either intermediate to both the parents or resembled to their male parents. Here, we also report the interspecific wide hybridization in Vigna through bridge species crossing strategy where the F1 of urdbean × moongbean was hybridized separately with ricebean and adzukibean. All the interspecific hybrids of urdbean and ricebean showed resistant reaction to Cercospora leaf spots.
