Abstract
A field trial was conducted at Sugarcane Research station Tiruvalla during 19S1 with selected clones after screening the hybrid progeny of the intervarietal cross Co 775 x Co 453* The investigation was conducted with the object of selecting superior hybrids with economic attributes from the progeny possessing wide spectrum of variability by evaluating genetic variability and assessing the extent and magnitude of heterosis.
The preliminary studies on the seedling progeny proved its variability for economic attributes. Weight of cane per stool recorded the maximum coefficient of variation followed by number of shoots and number of millable canes per stool. This attribute had positive correlation with all the yield components studied except H.R.Brix. Among the yield components# number of millable canes established the closest association with cane yield.
High heritabillty was displayed by almost all the attributes assessed in the clonal population# the maximum being recorded by arrowing and as such these characters were less influenced by environmental variations
