STABILITY OF YIELD AND ITS COMPONENTS IN CHICKPEA (CICER ARIETINUM LINN) FOR CHHOTANAGPUR REGION

Forty-two lines of chickpea (Cicer arietinum Linn) including two checks grown during
winter season (rabi) for three years 1988-89, 1989-90 and 1990-91 in twelve environments
were evaluated for stability parameters of Chhotanapur regions. Pooled analysis of
variance revealed that the mean sum of squares due to genotypes and environment for
primary branches/plant, secondary branches/plant and grain yield/plant (g) found highly
significant ( except primary branches /plant) indicating presence of high variability among
the genotypes and environment. Environmental (Linear) was found highly significant
for all the characters which indicated variation in weather condition of the location.
The pooled deviation (non-Linear portion of the variance) was found highly significant
for all the characters. The environment+ (Genotypes x environment) interaction were
found highly significant, showing important role of environment and genotype x
environment interaction to these characters. Considering all the characters the genotypes
ICCL86309, ICC11141, ICCL84204, ICCL 85211, ICCL86211, ICCL87208, ICC5003,
ICCL85307 having bi= 1 and S2 di = 0 found highly promising for average yielding
environment. While genotypes ICCL 84303, ICC5003 having bi>1 and S2 di= 0 found
promising for richer environment. For poor environment genotypes ICCL 86226,
ICCL87233 having bid promising
