A set of 107 varieties representing a wide range of variation for plant height and maturity were classified into 16 possible combinations of 4 height and 4 maturity groups. Increased plant height and days to flower contributed positively to the fodder yield. Increased vegetative growth in terms of leafiness and height was desirable only in early genotypes. Days to flower accounted for 72% of the variation in grain yield and 82% of the variation in leaf number. Early flowering and low leaf number was correlated with higher yield. The relationships among plant height, flowering, time and grain yield were non-linear. The optimum plant type is quantified to be combining 68 days to flower and 175cm plant height assuming fixed number of leaves and panicle branches
