192份陆地棉杂交种的遗传多样性分析
Genetic Diversity Analysis in 192 Gossypium hirsutum L.F1 Hybrids
摘要
Abstract
To screen high yield and high quality cotton hybrid combinations,192 F1 hybrids with 15 experimental materials Gossypium hirsutum L.cultivars as parental configurations were used as experimental materials.Correlation,principal component and regression analyses were used to explore the relationships among main agronomic traits,yield and fiber quality.The results showed that yield indexes such as single boll weight,seed cotton yield and lint cotton yield were negatively correlated with the number of the first branch.The fibre upper half mean length and fiber uniformity fiber of cotton fiber quality had a positive interaction with the main agronomic traits,while the macronaire value and fiber maturity had a negative interaction with the main agronomic traits.After dimensionality reduction of 16 indexes,5 principal components were extracted,which were named as bolling factor,yield factor,quality factor,growth factor and clothing factor,explaining 81.63%of the population variation.8 optimal regression models were constructed with yield and quality traits as dependent variables and main agronomic traits as independent variables to provide a basis for rapid and accurate selection of population materials to meet different needs.Above results provided theoretical basis and material support for cotton variety breeding.关键词
