Isolines in Cotton: Effects of Nine Dominant Genes1

  1. R. J. Kohel and
  2. T. R. Richmond2

Summary

Summary

Nine isolines of cotton, Gossypium hirsutum L., were developed by backcrossing lines carrying dominant marker alleles at a total of nine loci to Texas Marker-1. The marker alleles were isolated into separate lines and backcrossed for eight generations to provide a common genetic background in which the effects of the individual marker loci could be evaluated and characterized. The effects of the qualitative characters on quantitative agronomic traits were determined for each line in a replicated performance test and compared to the performance of the recurrent parent. Certain quantitative traits of the isolines remained variable, and this variability was interpreted to be caused by linkage associations.
