Abstract
A study was carried out to access the genetic variability in a set of 190 recombinant inbred lines (RILs) of rice derived from MTU1010 and BR2655. Plant height and number of productive tillers per plant recorded high PCV and GCV during kharif 2016, whereas number of filled grains per panicle, grain yield per plant, grain zinc concentration and grain iron concentration during rabi 2016-17.The estimates of PCV were slightly higher than the corresponding GCV estimates for all the traits studied indicating that the characters were least influenced by the environment. High heritability coupled with high genetic advance as per cent of mean was noticed for traits like plant height, number of productive tillers, number of filled grains per panicle, 1000-grain weight, grain yield per plant, grain iron concentration and grain zinc concentration respectively during kharif 2016 and rabi 2016-17 indicating that traits are under additive genetic control, simple selection would likely be effective for further improvement of these traits in desirable direction. RILs J16, J144 and J146 have shown higher grain yield per plant with high iron and zinc concentrations.
