Abstract:

The present investigation consists of 39 rice genotypes used for studying genetic variability parameters, correlation and path analysis which was carried out at Field Experiment Centre, Department of Genetics and Plant Breeding during Kharif 2018 in Randomized Block Design with three replications. The data were recorded for 13 quantitative characters to study genetic variability, heritability, genetic advance, correlation and path analysis. Analysis of Variance showed significant differences for all characters under study at 1% and 5% Level of Significance, indicated that presence of ample genetic variation among genotypes. On the basis of Per se performance of grain yield per plant was exhibited by TP 30614 followed by TP 30601, TP 30607, TP 30600. High estimates of GCV and PCV was recorded for spikelet’s per panicle followed by grain yield per plant and biological yield per hill. High heritability coupled with high genetic advance as percent mean is recorded for number of spikelet’s per panicle followed by number of panicles per plant and number of tillers per plant indicating predominance of additive gene effects and possibilities of effective selection for the improvement of the characters.
