湖南省茄子种质资源调查与评价鉴定
|
摘要
以湖南省22份地方茄子种质资源为材料,对茄子种质24个主要数量和质量性状进行调查,结合多样性分析和聚类分析的方法,旨在为茄子种质资源的进一步研究和种质创新提供科学依据。结果表明,22份茄子资源的主要数量性状存在较大的差异,收集的茄子种质多为早熟或中熟的卵圆紫茄;基于聚类分析,22份种质可分为两大类四个亚组,第I类群可作密植型品种选育材料,第III亚组可作高产型品种选育材料;运用主成分分析可将12个株型、果实相关性状集约于5个主成分上,主成分1和2命名为质量因子,主成分3和5命名为株型因子,主成分4为熟性因子,5个主成分的累计贡献率为85.865%,基本保持了12个性状的大部分信息。
A total of 24 major quantitative and quality traits of 22 eggplant landraces collected in Hunan Province were measured and analyzed using cluster and principal component analyses in this study.The results showed that the main quantitative traits of the eggplant germplasms were quite different.Most of the collected eggplant germplasms were early-maturing or Medium-maturing oval purple type.Based on cluster analysis,22 eggplant germplasms were divided into two main groups,which were further divided into four subgroups.Gemplasms in group I could be used for breeding dense-planting varieties.While,germplasms in subgroup III could be used for breeding new varieties with high yield.Using principal component analysis,12 quantitative and fruit-related traits were clustered on 5 principal components.Of which,principal components of No.1 and No.2 were named as quality factors.Principal components No.3 and No.5 were named as plant type factors.Principal component No.4 was recognized as maturity factor.The cumulative contribution rate of 5 principal components was up to 85.865%,which included most of the variances among the 12 traits.
