Rooting Pattern as a Selection Parameter of Wheat Varieties Under Moisture Stress

Abstract

Sixteen wheat varieties were studied under rainfed condition in heavy black sol with a view to evaluate their yield potential on the basis of root growth pattern in mois ture stress condition, Varieties viz, C 306, Hy 633. Hy 11. Hy 65, PKD 14 HD 1625 with greater number, deep vertical penetration and a more horizontal spread of seminal roots proved to be drought escaping and high yielding. Earlier initiation of crown roots coupled with their more number and greater length was found to be of great significance for an additional moisture and nutrient absorption and substantial vigour, which ultima tely result in higher productivity.
