37 sweet sorghum cv. were evaluated for sugar, solubles, grain, fibre and leaf production in 1st and ratoon crops under irrigation at Ayr, N. Queensland, over the winter-summer period. Highest sugar yields were from cv. Rio, which produced 3.6 and 1.6 t/ha over 145 and 79 days from 1st and ratoon crops, resp. Highest solubles yields of 7.6 and 4.8 t/ha were produced by cv. Italian over 141 and 81 days. The highest grain yield was 5.7 t DM/ha in the 1st crop by cv. FS26. Stem fibre yields of about 9 t DM/ha were realized from the higher yielding cv. In the 1st crop, sugar and solubles yields were found to be negatively correlated with grain yield, early development rate and fibre yield. They were positively correlated with time to maturity, plant leaf area and LAI at anthesis, a low position of the largest leaf on the stem, DM yield of plant fractions, high stem-juice extraction rates, and degree days and accumulated radiation received. In the ratoon crop, age and environmental variables showed a weaker association with yields. Productivity of fermentables appeared to be comparable with that of sugar cane for the region
