Growth and Fruiting Characteristics of Deltapine Seed Stripper Cotton Varieties

T.A. Vagts, M. Bates, S.W. Fuchs and D.H. Schulze


Cotton growers continually work with new cotton varieties and are pushing these varieties to produce a high yield crop in a shortened period of time. Two new stripper varieties recently released by Deltapine Seed have performed well under a shortened growing season. In order to effectively manage these new varieties in different environments, growth and fruiting parameters need to be known. Cotton plant mapping is a tool used to quickly and effectively characterize the growth and fruiting parameters of cotton varieties across differing environments and management practices. Seven replicated on-farm trials were set up across Texas and Oklahoma in 1997 to effectively characterize the growth and fruiting characteristics of two Deltapine Seed "stripper type" cotton varieties. The plant map data indicates, and is confirmed by the lint yield data, that DP 2156 is more determinant and will set a crop in a very short time period. DP 2156 yielded as well as the standard HS26, but was less than DP 2379 and DP 5409. DP 2156 is most likely best adapted for an environment in which DD60's will be limited either due to a short growing season or late planting. DP 2379 generally is a taller, more columnar type plant with a longer affective bloom period, indicating that it is less determinant and would benefit from a longer growing season. DP 2379, when placed in a full season environment, will look and yield very similarly to early maturing picker type cotton varieties.
