Study on correlation coefficient and path coefficient analysis in the accessions of Sewan grass ( Lasiurus sindicus Henr.) for green fodder yield and related traits

Abstract

Indigenous sewan grass is popularly known as the king of desert grasses. The present study was conducted to determine the variability (through PCV only), correlation and path coefficients among eleven green fodder yield and related characters in 30 accessions of sewan grass. Number of tillers per plant and dry matter yield per plant showed high PCV whereas it was moderate for leaf length, green fodder yield per plant, dry matter yield per plant, and leaf: stem ratio. Number of tillers per plant, spike length and dry matter yield per plant had significant positive correlation with green fodder yield per plant. The path coefficient analysis at phenotypic level revealed that green fodder yield per plant had exhibited largest direct effect on dry matter yield per plant followed by days to complete seed maturity, plant height and number of tillers per plant. Selection based on these traits would ultimately improve the yield.
