Variation in Plant Height and Monopodial Branches among Selected Cotton Cultivars

F.M. Bourland and B.W. White


 
ABSTRACT

Branching habit, plant height, earliness, and yield of plants in two stand densities were measured for five cotton, Gossypium hirsutum L., cultivars in 1981 and 1982. Significant variation between stand densities and among cultivars was found for each measurement. In sparse stands, plants were taller with a greater number of and longer monopodia branches than plants in optimum stand density. Maturation was delayed and yield reduced in the low stand density. Number and length of monopodia and plant height increased within each stand density as relative maturity of the cultivars was delayed. Increased yield was best explained by decreased plant height and increased monopodia development. These data suggest that emphasis on early maturation in cotton breeding has resulted in morphological changes in plant structure.
