Abstract  

Nine early maturing sugarcane clones and their 12 morpho-physiological characters were studied in 2015-16 and 2016-17 crop seasons under inorganic environment to assess their genetic distance and characters association. The results of the experiment revealed that variety CoPk 05191 had greater genetic distance from CoS03251 (239.401), CoLk011201 (227.923) and UP 05125 (201.355), medium genetic distance was between Co098014 and Co 011201 (224. 618), Co098014 and UP05125 (179.927), and Co098014 and CoS03251 (178.029). The hybridization between the aforesaid combinations of clones can produce heterotic and transgressive genotypes with higher cane and sugar yield. The cane yield showed strong positive and highly significant correlation with cane height (r= 0.948**), single cane weight (r=0.817**), number of millable cane (r=0.748**), and green top yield (r=0.653**). Being highly correlated with cane yield, the characters like cane height, cane weight, NMC and green top weight need special focus while making selection for higher cane and sugar yield.
