Abstract
Sugarcane is an important source of white sugar in tropical and subtropical areas worldwide. Besides used for sugar extraction, sugarcane produces numerous valuable byproducts like, ethanol, alcohol, and bagasse etc. Considering the importance of crop present study was planned to examine sugarcane genotypes for cane yield through yield contributing traits in natural field conditions. Forty sugarcane genotypes were evaluated in field conditions. At the age of 12 months, data were documented for cane height, cane diameter, leaf area, tillers per stool, internodes per cane, intermodal length, single cane weight, brix percentage and sugarcane mosaic virus (SCMV) incidence and severity. Results revealed that sugarcane genotypes were significantly differed with respect to the studied plant parameters. The highest heritability (92%) was observed for weight per stool followed by weight per cane (87%) and emergence percentage (70%). Viral disease scoring suggested that genotypes SC-22, SC-38 and SC-4 were observed as resistance/tolerant against SCMV while SC-16, SC-31, SC-36 and SC-9 were highly susceptible. Sugarcane genotypes SC-11, SC-40, SC-24 and SC-20 were found excellent for sugar recovery. The highest incidence of SCMV was observed in genotype SC-31 with very low brix percentage Principle component analysis indicated that first five PCs had 78.59% of the total variation with eigenvalue more than 1. Scree plot displayed that first five PCs contained major portion of variability. Scatter plot of 40 genotypes SC-3, SC-4, SC-20, SC-32 and SC-8 were found maximum diverse being apart from others for studied characters. Biplot indicated that intermodal length and emergence percentage showed least variations and sugarcane genotypes SC-3, SC-4, SC-20 and SC-33 were found genetically diverse genotypes for different traits under study.
