dc.description.abstractA series of studies were conducted at the Federal Experiment Station, Mayaguez, Puerto Rico, to determine the characteristics of seed size and their effects on the growth, development and utilization of Sorghum bicolor (L.) Moench. In one study 586 items from the Texas Agricultural Experiment Station-USDA sorghum conversion program were evaluated for seed and seedling characteristics. In other experiments selected varieties from these 586 varieties were studied. Three stocks which had large differences in seed weight and seed number per head were studied in crosses, reciprocal crosses and backcrosses. There was a very strong negative correlation between weight of 1000 kernels and the number of seeds per head. Regression analyses indicate that for each one gram increase in weight per 1000 kernels there was a decrease of 77.221 seeds per head. Selected crosses show even greater reductions of seed per head if seed size is increased. Yield or weight of grain per head was greatest when the female was the smallest seed type. Heritability for seed size was high but quite low for number of seeds per head.en
