Abstract:
The experiment carried out at Agriculture research farm, Lovely Professional University, Phagwara, Punjab. Heterosis for yield and its component traits were studied in 9 genotypes and their 36 F1`s in wheat (Triticum aestivum L.). The magnitude of heterotic effects was high for number of effective tillers per plant, number of spikelets per spike and Days to maturity; moderate for number of grains per spike, Days to 50% heading, harvest index, chlorophyll content, grain yield per plant and spike length; and low for biological yield per plant, plant height and protein content. The highest, positive and significant heterobeltiosis for grain yield per plant and some of its component traits were recorded in the crosses, IC 78749 X IC 532889, IC 78801 X IC 78737, IC 78749 X IC 138866, IC 66520 X IC 78801, IC 78751 X IC 55681, IC 78749 X IC 78737, and IC 55681 X IC 78737.
