- Abstract
Sugarcane (Saccharum sp.) is one of the world's most commercial crops as it is the main source of sucrose. Sugarcane breeding programs are concentrated to improve the sucrose content and cane yield. Sucrose content is important for sugar industries and cane yield is profitable concern for farmers. Selection of genetically rich and diverse genotypes is necessary to achieve both the improvements. In the present study, initially physicochemical analysis performed for 24 promising sugarcane cultivars, mainly for sucrose accumulation and cane yield. Among the 24 cultivars, 10 cultivars were selected for further RAPD molecular screening of potential genotypes. PCR analysis was done using 20 RAPD primers. The genetic similarity and UPGMA clustering were performed for all 10 sugarcane cultivars and compared the analysed data of both physicochemical and RAPD analysis. The study showed S1, S8, S11, S18 and S23 as closest ones and S2, S24, S15 as distant ones. This evaluation of genetic relatedness among 10 cultivars revealed primary information for the selection of high sucrose accumulative and cane yielding parental genotypes for further sugarcane breeding.
