The effect of normal and okra leaf types, glabrous and hairy plants, normal and frego bracts and their combinations in near-isogenic cotton lines on lint yield, earliness, and fiber quality was studied in tests conducted at College Station and McGregor in 1983 and 1984. Significant differences between years, locations, isolines and their interactions were obtained.

There was no significant difference between normal leaf and okra leaf for earliness or total lint yield. Both leaf types with frego bract had a reduction in earliness. The isoline with the okra leaf and frego bract combination had a significantly reduced yield, indicating the unfavorable association of these two traits. There were significant differences among leaf types and bract types for lint percent, gin turnout, fiber length, uniformity, strength, elongation and micronaire.

Glabrous and hairy types had no effect no yield. However, frego bract significantly reduced yield in both the glabrous and hairy types. Bract, hairy and glabrous types did not influence fiber quality. Fiber traits were effected more by the genetic background of the parent rather than the morphological traits.
