Abstract
The objective of this study was to identify superior clones suitable for mechanical harvesting, which is essential to improve the production efficiency, cost effectiveness, cane loading efficiency infield losses and also to investigate the relationships among the yield and quality parameters with cane yield and sugar yield in sugarcane. This experiment was conducted at Regional sugarcane and Rice Research Station, Rudrur, Nizamabad district, Telangana state in Randomized Block Design (RBD) with three replications. The analysis of variance revealed significant differences among genotypes for fifteen yield, quality and mechanization amicable characters. Correlation coefficient results indicated that cane yield was positively correlated with commercial cane sugar, number of tillers at 120 days after planting, cane height, cane girth, single cane weight. So, selection for cane yield alone will also increase the other characters because these traits are positively correlated with cane yield. The Angle of inclination is negatively correlated with cane yield and positively correlated with ratio of crown weight to cane weight, brix%, sucrose%, purity% and CCS%. Results indicate that the genotypes should be selected on the basis of number of millable canes, cane length, cane girth and single cane weight for getting higher sugarcane yield. Furthermore, mechanization amicable genotypes can be selected which are near to erect nature and also having less crown weight.
