Screening of rice genotypes against Ustilaginoidea virens, an incitant of false smut
Keywords:
False smut, Rice, Screening, Genotypes artificial inoculationAbstract
A field experiment was conducted to evaluate rice genotypes against false smut during Kharif-2022 under artificial inoculation conditions at the experimental farm of Rice and Wheat Research Centre, Malan. Out of sixty one genotypes, seventeen genotypes (HPR 3236, HPR 3239, HPR 3243, HPR 3248, HPR 3250, HPR 3251, HPR 3253, HPR 3254, HPR 3260, HPR 3261, HPR 3262, PB 1121, Kasturi, HPR 2612, HPR 3228, HPR 3218, HPR 3226) showed highly resistant reaction, seven (HPR 3256, HPR 3259, HPR 2929, HPR 3213, HPR 3211, HPR 2703, HPR 2696) resistant, twenty three moderately resistant, five moderately susceptible while all the nine hybrids (Arize 6129, Arize 6444, Arize Swift, AZ 6508, BS 10008, DR 8101, PAC 834, PAC 807 Plus, Arize 6129 Gold (susceptible check) showed susceptible reaction to false smut on the basis of disease incidence. The promising rice genotypes obtained after evaluation against false smut can be utilized in breeding programme for false smut resistance.Downloads
