Studying the Negative Relationship between Yield and Fiber Quality

An experiment was conducted to study the negative relationship between yield and fiber quality. Ten F2 and F2:3 populations were developed from crosses involving four parents with high yield/high fiber quality phenotypes and one parent with a high yield/poor fiber quality phenotype. The ten populations were developed among the five parents following a half-diallel mating design without reciprocals. The study tests the hypothesis that mating two parents with known high yield/high fiber quality phenotypes result in a greater population mean and number of offspring with high lint percent and HVI fiber quality.
