The prevalence and distribution of pathotypes and mating types of Ascochyta rabiei (Pass.) Labr. in India was evaluated during the winter (October to March) seasons of 2017-18 and 2018-19. Forty-fi...

Most of the commercially approved cultivars of Phaseolus vulgaris were susceptible to bean common mosaic virus (BCMV) which results in severe reduction in yield. In the present study, a total of 350 common bean genotypes were screened under natural epiphytotic conditions and artificial inoculation during 2016–2017, 2017–2018 and 2018–2019. Only eleven genotypes viz., EC400445, EC400414, ET4515B, EC540173, IC360831, BD9116291, EC31084, EC541703, ET8409, IC340947 and IC356024 were found stable resistant. The BCMV infection was confirmed through reverse-transcription polymerase chain reaction using coat protein gene amplification. The amplified region was sequenced and analyzed. Percent identity of BCMV-K with reported BCMV strains from different parts of world and based on nucleotide sequence ranged between 94% and 99.70% and maximum identity (99.70%) is observed with the strains of Uttar Pradesh (MT265069) and Himachal Pradesh (FJ387162, EU492546). The identified resistant sources from this study could be utilized as donors to develop BCMV resistant common bean cultivars.
