Abstract:
A field trial with selected sugarcane hybrid clones of the intervarietal cross Co 775 x Co
453 was conducted at the Sugarcane Research Station, Thiruvalla to study the different genetic
parameters in the settling progeny. High heritability was observed for shoot count, total weight
of cane, number of miIIable canes, length of internode, length and girth of cane and weight of single
cane at harvest. Cane yield and its components displayed low coefficients of variation. Correlation
studies indicated that cane yield has positive correlation with all majoreconomicaltributes except
U.K. Brix. The closest association of cane yield with number of millablc canes at harvest was well
established with the present study. The study suggested that probabilities of varieties combining
higher yield and quality attributes are remote.
