New sources of genotypes against leaf spot and powdery mildew diseases in Greengram

Abstract

Green gram genotypes/germplasms were evaluated to identify the sources of resistance to leaf spot and powdery mildew diseases. Screening was done under natural field conditions at Regional Agricultural Research Station (RARS), Warangal, Telangana State, India. The experimental material consisted fifty seven AICRP and state twenty one Green gram entries with one check during Kharif-2017 and 19 AICRP and 12 state green gram entries with a check during Rabi-2017, which were screened against the major diseases at RARS, Warangal. Out of one hundred twelve Green gram entries, eight entries viz.,VGG 16-055, VGG 16-036,LGG 607, Pusa 9072,VBN(Gg)2, MGG 385,VGG 15-030 and VGG 16-027 were moderately resistant to Cercospora leaf spot disease; two (TM-96-2 and TARM -1) entries were found highly resistant to powdery mildew Disease. Resistants’ can be exploited to develop high yielding varieties of green gram by breeding.
