Combining Ability, Heterosis and Multivariate Analysis for Physiological and Agronomic Traits of Rice Genotypes Under Normal and Water Stress Conditions

The main obstacles to rice cultivation in Egypt and the world are lack of irrigation water and elevated temperatures, because rice production is extremely sensitive to water shortage; there is a need for the evolution of genotypes that are tolerant to drought. To this achieved, 21 F1 hybrids develop...

Description
Summary:The main obstacles to rice cultivation in Egypt and the world are lack of irrigation water and elevated temperatures, because rice production is extremely sensitive to water shortage; there is a need for the evolution of genotypes that are tolerant to drought. To this achieved, 21 F1 hybrids developed from seven parental genotypes using half diallel mating design and assessed under normal and water stress at Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt. The grain yield and most traits significantly differ ( p
