Abstract
The investigation on variation studies in chickpea
(Cicer arietinum L.) was conducted on 62 genotypes of chickpea to
know the variability, interrelationship among yield and its
components, their direct and indirect effect on seed yield.
Observations were recorded for days to 50 per cent
flowering, days to maturity, plant height, plant spread, number
of primary branches per plant, number of secondary branches
per plant, number of pods per plant, number of seeds per pod,
100 seed weight, protein content and seed yield per plant.
A wide range of variability was observed for all the
characters except number of primary branches per plant and
number of seeds per pod. The character pods per plant exhibited highest range of variability followed by plant spread,
plant height, days to 50 per cent flowering, days to maturity,
seed yield per plant, 100 seed weight. Protein content and
number of secondary branches per plant showed moderate
amount of variation.
Genotypic and phenotypic coefficients of variation
were highest for seed yield per plant followed by pods per plant,
plant spread, number of primary branches per plant, number of
secondary branches per plant and 100 seed weight. High
heritability associated with high genetic advance was observed
for number of pods per plant, seed yield per plant, plant spread,
number of primary and secondary branches per plant, 100 seed
weight and number of seeds per pod suggesting that selection of
these traits would be effective for the desired improvement in
chickpea.
The straight selection on the basis of phenotypic
performance alone would not, therefore be rewarding in the
improvement of these traits, indicating non additive gene action
and breeding methods, to exploit non additive gene action
through heterosis may be followed.
The significant positive correlation was reported
between seed yield per plant and primary branches per plant
followed by secondary branches per plant, number of seeds per
pod, 100 seed weight, days to maturity, days to 50 per cent
flowering and plant height.
