Abstract:
The present investigation was at The University Research Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during Kharif season of 2016. The experimental material comprised of A set of 24 rice germplasm lines including three varieties. Out of 24 rice germplasm lines and varieties, 13 germplasm lines viz. IC75889, IC75767, IC217492, IC216609, IC217509, IC216606, IC75829, IC216579, IC216612, T-12, IC216563, IC 218607 and ARC 10550 showed the resistant reaction. Heritability governs the resemblance between parents and their progeny whereas; the genetic advance provides the knowledge about expected gain for a particular character after selection. Heritability suggests the relative role of genetic factors in expression of phenotypes and also acts as an index of transmissibility of a particular trait to its offspring. However, the knowledge of heritability alone does not help in formulating concrete breeding programme, genetic advance along with heritability helps to ascertain the possible genetic control for any particular trait. The nature and extent of the inherent ability of a genotype for a character is an important parameter determining the extent of improvement of any crop species. The parameter, genetic advance as per cent of mean (GA) % as mean is more reliable index for understanding the effectiveness of selection in improving the traits because its estimates is derived by involvement of heritability, phenotypic standard deviation and intensity of selection.
