 ABSTRACT

In the present study F5 and F6 generation of crosses between WH 711 and WH 542 of bread wheat (Triticum aestivum L.) was evaluated for yield and its contributing traits under timely and late sown condition. Parent progeny regression analysis was undertaken to determine the genetic potential transferred from one generation to next generation. The significant and positive inter-generation correlation and regression was observed for character like grain yield per meter, grain length, plant height, harvest index, grain weight per spike, grain breadth, number of tillers per meter and biological yield per meter. It indicates the chances of selecting high yielding segregants at early generations. The narrow sense heritability for different characters based on parent offspring regression coefficient was moderate for grain yield per meter (78.80%), grain weight per spike (68.60%), harvest index (63.20%) and number of tillers per meter (54.00%) under both timely and late sown conditions. Higher the narrow sense heritability, higher is the chances of improving the characters through selection.

Keywords: Wheat, Narrow-sense heritability, Inter-generation correlation, Regression.
