 ABSTRACT

Pigeonpea genotypes obtained from ICRISAT and AICRP centers wereevaluated under field condition during Kharif 2015 for resistance to PPSMV at ZARS, GKVK, UAS, Bengaluru, to identify the resistant source. Ten advanced varietal trial entries tested against SMD. None of the entries showed resistant reaction or moderately resistant reaction to SMD. Their disease incidence varied from 82 to 100%.  Out of 22 IVT medium duration entries, none of the entries showed resistant reaction but all were showed more than 50 per cent disease incidence except Bahar to SMD, whereas out of thirteen IVT early duration entries, only one entry RKPV405-10 showed resistant reaction but others were susceptible to SMD and the disease incidence ranged from 68 per cent to 100 per cent. Out of 61 Hyderabad, ICPL99095 and ICP7035 showed resistant reaction and ICPL20123 showed moderately resistant reaction and rest of the entries were showed susceptible reaction.
