HETEROSIS FOR HEAT TOLERANCE, PROTEIN CONTENT, YIELD AND YIELD COMPONENTS IN BREAD WHEAT (TRITICUM AESTIVUM L.)

Published on

Morpho-physiologically diverse seven varieties of wheat Triticum aestivum L. em.
Thell) were grown alongwith their hybrid combinations in a randomised block
design with the three replications. Significant heterosis over better parent was
observed for grain yield, heat injury, chlorophyll content and stomatal frequency.
There was significant positive heterosis for protein content, however such crosses
having high protein content were relatively low grain yielders. The cross
Hindi 62 x Ajantha exhibited significant heterosis over mid and better parent
(Hindi 62) for heat injury and grain yield per plant.
