Abstract:

A field experiment was conducted at Dryland Farm of S.V. Agricultural College, Regional Agricultural Research Station, Acharya N.G. Ranga Agricultural University, Tirupati during rabi season, 2016-17. The study aimed to characterize blackgram genotypes for biochemical variability for YMV tolerance and susceptibility under yellow mosaic disease infection. In the present study, treatments consist of totally ten blackgram genotypes (5 known tolerant + 5 known susceptible). Biochemical parameters viz., total chlorophyll, total phenols, total soluble sugars and total proteins were estimated spectrophotometrically from leaf samples collected at 30 and 50 days after sowing (DAS) from whitefly infested and uninfested plants. The parameters showed different activity levels at different times after the infestation. The tolerant genotypes recorded significantly higher mean total chlorophyll and total phenols as well as lower mean total soluble sugars and total proteins compared to susceptible genotypes. Among the genotypes TBG- 104 and LBG- 752 showed higher YMV tolerance compared to other genotypes. Among all the ten genotypes LBG-752 and recorded 21.41 per cent higher seed yield followed by TBG-104 and PU-31 compared to mean value of ten genotypes. Genotypes PBG- 1, LBG-623 and LBG-685 (susceptible genotypes) recorded lower seed yield compared to other genotypes.
