为科学评价国内肉用老南瓜品种,对参展的41个肉用老南瓜品种的始花期、第一坐瓜节位、果长、把长、茎粗、节间长、最大叶纵横经、单果重、果肉厚和可溶性固形物含量等主要植物学性状进行了多样性、相关性和聚类分析。结果表明,41个肉用老南瓜品种在把长、单果重、果长和肉厚等性状变异幅度较大,在始花期性状上变异幅度较小;各性状之间均存在显著或者极显著的相关性。聚类分析表明41个肉用老南瓜可以分为3组,其中第1组在多个性状上优于第2和3组群,但各组间及组内品种间的相似性较高。研究结果为老南瓜育种的优良性状选择和亲本选用提供了依据。
In order to scientifically evaluate the varieties of old pumpkin meat for domestic use, the first flowering period of the 41 varieties of old pumpkin meat for the exhibitors was the first to sit on the melon node and fruit length. The length, the stem length, the internode length, the largest leaf length and breadth, Heavy, flesh thickness and soluble solids content of the main botanical traits such as diversity, correlation and cluster analysis. The results showed that the 41 varieties of meat pumpkin varieties had greater variation in the length, fruit weight, fruit length and flesh thickness, with less variation in the initial flowering stage, and significant or significant differences among the traits Correlation. Cluster analysis showed that 41 meat pumpkins could be divided into three groups, among which the first group was superior to the second and third groups in multiple traits, but the similarities among the groups and among the groups were higher. The results provided the basis for selection of elite squash breeding and selection of parents.
