Abstract

Studies on character association and path-coefficient analysis were conducted on forty three rice genotypes including thirty hybrids and thirteen parents for grain quality traits on grain yield. Analysis of variance revealed considerable variability among the genotypes for all the characters studied. The correlation analysis indicated that grain yield was significantly associated with kernel breadth, breadth wise expansion ratio and water uptake at genotypic level. Results of path-coefficient analysis revealed linear elongation ratio had the highest positive direct effect on grain yield followed by breadth wise expansion ratio, gel consistency, kernel L/B ratio and alkali spreading value. This study revealed that genetic improvement of grain quality in rice is admissible by selecting characters having high positive correlation and positive direct effect on grain yield.
