Abstract or Summary
  • Ten wheat crosses (four winter x spring and six winter x winter) involving F₃ and F₄ generations and their respective winter parents were used to determine whether the early generation selection would be effective for kernel hardness and grain protein content. In 1980, twenty individual F₂ plants were selected with good phenotypic appearance from each cross. The F₃ progeny rows along with their respective winter parents were grown in a replicated yield trial in 1981. Significant differences were found among the crosses for kernel hardness, percent protein, grain yield, 1000 kernel weight, and heading date. Superior progeny with values above the winter parent were observed for both kernel hardness and percent grain protein in both F₃ and F₄ generations in winter x spring corsses. Transgressive segregation was also observed beyond both parents in five of the six winter x winter crosses for both traits. Correlations between F₃ and F₄ generations were found for kernel hardness. A high correlation coefficient between generations for kernel hardness indicated that early generation selection would be effective for this trait in these populations. Small correlations were found in most of the crosses between the F₃ and F₄ generations for percent grain protein. Similarly small correlation between years for the winter parents indicated that percent grain protein was largely influenced by the environment and early generation selection may not be effective for this trait. Little association was observed between kernel hardness and percent grain protein when all crosses are considered. However, significant negative correlations were observed in three of the four winter x spring crosses in the F₄ generation. The correlation between grain yield and hardness was low while the correlation between grain yield and protein content was significant and negative.
