Estimation of correlation among the morpho-physiological traits in MAGIC population of chickpea (Cicer arietinum L.)

Abstract

An investigation entitled “Estimation of correlation among the morpho-physiological traits in MAGIC population of chickpea (Cicer arietinum L.)” was carried out with 40 genotypes in F4 derived F5 MAGIC lines consisting of eight parents.ICC-4958, ICCV-10, JAKI-9218, JG-11, JG-130, JG-16,.ICCV-97105, ICCV-00108 during rabi 2012-13 and 2013-14.The observations were recorded for quantitative traits namely, days to 50% flowering, days to maturity, plant height (cm), pod per plant, primary branches, secondary branches, pod length (cm), seed yield (g), 100 seed wt.(g),seed per pod, root length (cm), root wt., (fresh and dry) in (g), relative water content of leaf and partitioning coefficient to roots, stem, leaves and pods. The information was derived on phenotypic and genotypic correlation the values of correlation coefficient at genotypic level were higher than those for phenotypic counterpart. Plant height, primary branches, secondary branches, pod per plant, 100 seed wt. and seed yield had direct and positive effect. Root length, relative water content, partitioning coefficient to root, stem, and leaves showed positive and significant correlation. The developmental characters like days to 50% flowering and maturity contributed to grain yield indirectly via., plant height and 100 seed weight.
