Abstract:

Greengram also known as mungbean is an important pulse crop with remarkable source of high quality protein, vitamins, fibres and amino acid profiles. In India, it stands third in production. The lower productivity of greengram is attributed to biotic stresses, among which powdery mildew caused by Erysiphe polygni is one of the major fungal diseases and in severe cases it covers entire leaf area, affects the photosynthetic activity, reduces mungbean yield more than 50%. In the present study, 130 genotypes were screened against E. polygoni under natural epiphytotic condition at Main Agricultural Research Station, Dharwad during kharif and rabi, 2016. Among these, during kharif 2016 four genotypes (GPM-19, NUL-7, Vigna umbellata and Vigna trilobata) showed immune response, three genotypes (COGG-913, VAIBHAV and TARM1) were moderately resistant, six genotypes (GPM-10, GPM-23IPU-94-1, IPU-2-4, TBM-96-2 and IC277014)) showed susceptible reaction, 119 genotypes were highly susceptible to the disease. During rabi 2016, three genotypes viz., GPM-19, V. umbellata and V. trilobata showed immune response and four genotypes viz., NUL-7, COGG-913, TARM1 and Vaibhav showed moderately resistant response. Nine genotypes viz., IPU-94-1, IPU-2-43, TCR-262 V. sylvestris, GPM-23, GPM-10, TBM-96-2, IV277014 V. sylvestris, TCR-218 V. sublobata and IC-251416 V. sublobata showed susceptible reaction and the remaining 114 genotypes were rated as highly susceptible to the disease. None of the genotypes showed resistant response. These identified immune genotypes can be used in the development of resistant cultivars.
