Studies on genetic divergence in sugarcane plant and ratoon crops involving sixteen genotypes planted at RAU Pusa Farm, Samastipur, Bihar during 2012-13 and their consecutive ratoon during 2013-14 under low land area with water-stagnation 2 to 3 months to select profitable genotypes tolerant to water logging. Cane yield of plant crop was higher than the ratoon while for juice quality traits of ratoon crop showed better. All genotypes differed significantly with regard to the traits studied and displayed distinct marked divergence, grouped into five clusters for both crops following Tocher’s method. only Cluster I and II had more than one genotypes while Cluster III, IV and V were monogenotypic. | Diversity studies in plant and ratoon crops for selection of profitable sugarcane genotypes tolerant to water logging
