KARAKTER MORFOLOGI BERBAGAI GENOTIP KEDELAI TERHADAP CEKAMAN KEKERINGAN

Abstract

Drought stress is a soil water content at minimum conditions disturb soybean growth. The research objectives are to describe morphological responses under drought condition, determine effective selection criteria and select tolerant genotypes. The experiment was conducted at screen house of Agriculture Faculty of Jenderal Soedirman University. The experimental design was a randomized completely block design with two factors and three replications. First factor was eleven soybean genotypes (nine lines and two varieties). Second factor was three levels of drought stress; 90% KL, 60% KL, and 30% KL. The results show morphological characters that support drought tolerance are branch number, major node, total node, fertile pod, total pod, fertile seed number, root dry weight, shoot dry weight, and whole grain weight. The effective selection criteria are Mean Productivity, Geometric Mean Productivity, and Stress Tolerance Index. Tolerant genotypes are line G3, G4, and G10.
