Abstract : Nine yellow seeded mung (Vigna radiata L.) genotypes were evaluated along with three checks for their
yield performance during three years (2007, 2010 and 2011). Pooled analysis of variance and stability analysis were
performed. The genotypic (G) × environment (E) interaction and both variance due to genotypes and environment
were significant. The portioning of G × E interaction into linear and non-linear components indicated that
both predictable and unpredictable components shared the interaction. On the basis of stability parameters, the
top yielding genotypes such as BGS-9 (605.444 Kg/Ha), Sel-4 (519.778 Kg/Ha) and China mung (567.000 Kg/Ha)
exhibited high mean yield. Based on stability parameters the genotypes YM-5 (459.889 Kg/Ha), YM-8 (451.333 Kg/Ha)
exhibited low mean performance along with regression value nearer to unity (bi=1) and non significant deviation
from regression (S2 di=0) indicating the high stability and wider adaptability across the three environments. The
genotypes BGS-9 (605.444 Kg/Ha) and Sel-4 (519.778 Kg/Ha) exhibited high mean value and bi values (bi>1) and
non significant deviation (S2 di < 0) value indicating adapted for high performance environments (These genotypes
are sensitive to environments and give maximum yield when inputs are not limited).
