EFFECT OF MOISTURE STRESS ON THE YIELD AND YIELD COMPONENTS IN BANANA AS INFLUENCED BY THEIR GENOME AND PLOIDY

Abstract

Banana cultivars representing seven genomic and three ploidy groups were subjected to moisture stress at 5th-8th leaf stage and at 8th-15th leaf stage. The yield and yield components were decreased by moisture stress. Highest reduction in fruit number and weight resulted in the decreases in bunch weight in the plants subjected to moisture stress at 8th-15th leaf stage. The cultivar predominating with acuminata blood and the triploids experienced higher degree of reduction in yield and yield components during moisture strees compared to that of the cultivars predominating with balbisiana blood of diploids and tetraploids.
