Synopsis In three crosses between high and low lint density varieties, lint density index was found to be quantitative in inheritance. Relatively large parent differences appeared to be governed by not more than 5 or 6 pairs of genes. In 2 crosses, heritability estimates of 35 and 43% were obtained from regression of F 3 means on F 2 plant values. Selection of high fiber density among single plants was found to be highly effective. A relatively high negative association between strength and lint density was found in one cross. Lint density index was highly associated with fiber number.
