The influence of characters association on behavior of sugarcane genotypes (Saccharum spp) for cane yield and juice quality.

摘要

The investigation was carried out at the Sugarcane Research Centre, Sudan (14, 48 N degrees ), during the season of 2003/2004 and 2004/2005. Eight sugarcane genotypes were evaluated in a randomized complete block design with four replications to study association of characters influenced the final behavior of eight sugarcane clones regarding cane yield characters namely; yield of cane (ton/ha), number of millable cane, stalk height, stalk diameter, single stalk weight and juice quality traits in terms of juice brix (%) juice pol %, juice purity % and cane fiber (%). The results indicated that genotypes R 579, SP 718210 and Co 6806 had shown superiority for yield of cane per ha where as genotype Co 527 followed by Co 997 were the best for juice pol percent. Characters association results showed a positive correlation between cane yield in one hand and number of millable stalks, stalk height, internodal number per stalk, single stalks weight on the other hand indicated improvement of one of these character may resulted in positive response of the other character. Negative association of cane yield with stalk diameter, juice pol and purity % was noticed in this study.
