Abstract:

An experiment was framed to know the genetic variability, heritability, genetic advance and character association among the lines homozygous dominant for gall midge resistance gene Gm4 in the genetic background of ADT 38 variety of rice in advanced backcross (BC1F5) generation of rice. The Phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) for all the characters studied. High GCV coupled with high PCV was exhibited by single plant yield. This result creates scope for selection of superior segregants. Moderate heritability coupled with high genetic advance was recorded for hundred grain weight indicating that the selection could be done at later generation. Highly significant positive correlation with single plant yield was exhibited by traits like number of tillers, number of productive tillers and number of filled grain per panicle. The path coefficient analysis reveals that the traits like number of productive tillers, number of filled grains per panicle, grain width, grain length/grain width ratio and hundred grain weight has a positive direct effect towards single plant yield.
