Abstract:

Groundnut is one of the major oilseed crops in the world. Variability studies are the basic studies to assess the genotypes for their variation in quantitative and qualitative characters. The extent of the genetic and non-genetic components of variation formulates proper breeding programme to reach the goal. A field experiment was conducted during kharif, 2010 at University of Agricultural Sciences, Dharwad to evaluate the genetic variation for yield and yield component traits in the mapping population. The field experiment was laid out in RCBD with 268 RILs (Recombinant inbreed lines) and their two parents (TAG 24 x GPBD 4) (Gowda et al., 2002). The seed phosphorous content ranged from 0.33 to 0.82% with high heritability, high GCV, PCV and GAM. Oil content and shelling percentage had lower estimates of GCV and PCV indicating a limited genetic variability for these quality traits. The average value of the test weight was 45.69 g with moderate PCV and low GCV values (12.40 % and 8.38%), respectively. The heritability and GAM estimates were moderate. The genetic advance was 5.33. The range for pod yield/plant was from 10.99 to 31.31 with a mean of 20.61. In the evaluated genotypes PCV and GCV values were moderate with high heritability with high GAM was observed.
