Association studies for yield components and quality Traits in Basmati Rice (Oryza sativa L.)

Abstract

The present study was conducted to elucidate character association among yield components and quality parameters utilizing the data recorded on thirty rice genotypes for twenty-two characters. Correlation analysis revealed that grain yield showed significant and positive correlation with tiller per meter, water absorb by 10g kernel, kernel breadth after cooking and breadth increase ratio after cooking. It showed significant and negative correlation with 100 grain weight, 100 kernel weight and plant height. Grain weight per panicle showed significant positive correlation with, 100 grain weight and 100 kernel weight. 100 grain weight showed highly significant and positive correlation with 100 kernel weight, kernel length before cooking and kernel breadth before cooking. kernel length after cooking, L:B. ratio and 100 kernel weight after cooking, while it showed highly significant and negative correlation with kernel elongation ratio and water absorb by 10g kernel. Therefore, we observed that morphological traits reflected positive as well as negative association with quality parameters, hence, careful selection required in enhancing characters that are negatively associated.
