Abstract

The present study aims to understand the degree, amount and nature of relationship between different morphometric and yield associated traits and path coefficient analysis in medicinally important plant. The genotypic correlation coefficient (r_g) was higher than phenotypic correlation coefficient (r_p), suggesting inherent relations for selected traits at their genotypic level. Highest direct contributor to seed yield was husk yield/plot (0.88), whereas, the lower indirect contributor to seed yield was plant height. The highest heritability and highest genetic advance were observed for the traits panicle/plant 98.57%, 157.79%, respectively suggesting it was possibly governed due to cumulative gene action. On the basis of overall mean performance, character contribution, correlation, path coefficient analysis, heritability and genetic advance, accessions GSD 36, GSD 38, GSD 42, GSD 45, and GSD 47 were identified as highest seed yielding accessions and could be exploited for commercial cultivation.
