Abstract/Description: | Groundnut is major rain fed oilseed crop and its production is mainly affected by biotic stresses (rust andlate leaf spot).Two backcross population were evaluated for yield and foliar diseases. ANOVA indicated significant differences for yield component traits and reaction to rust and LLS incidence. In both generations (BC1F3 and BC2F2) days to 50 per cent flowering and days to maturity exhibited low estimates of PCV and GCV values, whereas pod yield per plant and Spodoptera litura damage exhibited higher PCV and GCV estimates. High heritability coupled with high genetic advance as per cent of mean was observed for plant height, primary branches per plant, Spodoptera litura damage and pod yield per plant in both generations, indicates the additive gene control and scope for simple selection for improving these traits. Phenotypic correlations coefficients among characters indicated differences between BC1F3 and BC2F2generations. Lower incidence of LLS incidence at 90 days and spodopteralitura damage in BC2F2 generation as compared to BC1F3 generation as reveled by lower magnitudes of correlation coefficients and non-significant correlation |
