Correlation studies were done to find out the relation between stalk weight and its attributes and also to find out the attributes mainly responsible for stalk weight in five sugarcane genotypes in a field trial conducted at the Research Farm of El-Sabahia Agricultural Research Station, Alexandria, Egypt as planted crop in the sprin g of each of 2005 -2006 and 2006 -2007 seasons. These five sugar cane genotypes are G.T.54-9, G95-19, G.95-21, G.98-28 and Ph.8013. The results showed that the stalk weight of genotypes G.T.54-9 and G.95-19 had positive significant correlation with stalk length, stalk diameter, number of internodes and number of tillers, except number of tillers in G.95-19 was found to be insignificant. In G.95-21 and Ph.8013, though all the characters positively correlated with stalk weight, stalk length in case of G.95-21 and number of tillers in Ph.8013 had positive significant correlation with stalk weight. In variety G.98-28 non of the components had significant correlation with stalk weight. Among stalk weight the component, stalk length was found to be positive significantly correlated with stalk diameter, number of internodes and number of tillers in case of G.T. 54-9. Also, among stalk weight components, stalk diameter was found to be significantly different with number of internodes and number of tillers of the cane in all the varieties except in G.95-19, where stalk diameter did not have significant correlation with number of internodes and tillers. This indicates that the stalk weight of cane is not an independent characters but it is dependent on number of internodes and number of tillers of the cane. Multiple correlation coefficient between stalk weight and stalk length and stalk diameter was significant in varieties G.T.54-9, G.95-19 and G.95-21 indicating that the stalk weight has significant correlation with its attributes. In the other two varieties (G.98-28 and Ph. 8013) the contribution of these two characters was insignificant. Among the stalk length which had maximum contribution of 38.1, 37.59 and 35.45 percent in stalk weight of G.95-21, G.T.54-9 and G.95-19, respectively. The contribution of stalk diameter was of the order of 29.18 and 27.1 percent in the weight of G.T. 54-9 and G.95-19, respectively. These two characters contributed almost negligible in the stalk weight of variety G.98-28. Number of internodes and number of tillers of cane had significant and positive contribution in stalk weight of all the varieties. However, number of tillers contributed more as compared to number of internodes of cane to the stalk weight of variety G.T. 54-9 and Ph.8013. The respective contribution of number of tillers of cane was 53.91 and 45.25 percent in both varieties. In case of varieties G.95-19 and G.95-21, the contribution of number of internodes of cane to the stalk weight was more as compared to number of tillers of cane (40.1% in G95-19 and 33.33%in G.95-21). Multiple correlation coefficients were signification in all the cases. It could be concluded that increasing stalk length, stalk diameter, number of internodes and number of tillers should be the major selection criteria for the breeders for increasing stalk weight in sugar cane plants or genotypes in their breeding program.
