Association of quantitative and qualitative characters of sugarcane under water logging conditions

Abstract

Study on association of quantitative and qualitative characters of sugarcane under water logging conditions comprises 14 diverse released cultivar and advance lines along with four water logging tolerance checks. Field evaluation was carried out in Randomize Block Design for thirteen different morphological and quality parameters. Analysis of variance revealed significant differences among all the genotypes for the characters studied. Correlation coefficient studies indicated that number of tillers and sucrose percent (at genotypic level) and germination percentage was significant and positively correlated with cane yield. A high significant positive correlation with number of millable canes and commercial cane sugar yield was also observed. No significant association of cane yield with any of the quality characters was found. Path analysis revealed that commercial cane sugar percent, juice purity, juice brix, single cane weight and number of millable canes had high positive direct effect while sucrose percent revealed to have high negative direct effect on cane yield. Results from the analysis indicated that selection programme for high yielding water logging tolerant clones would be effective if it was based on number of millable canes, single cane weight, purity percent and commercial cane sugar percent.
