Analysis on the Genetic Characteristics of Male Flower Traits in the Hybrid Progeny of Kiwifruit Jinli and Moshan No.4
摘要
Abstract
Given that kiwifruit is a dioecious species,the selection and breeding of male varieties are crucial for advancing the kiwifruit industry.To develop superior male kiwifruit cultivars and investigate the genetic variation in hybrid offspring,this study used male plants derived from crosses between Actinidia chinensis Jinli and Moshan No.4.Comprehensive analysis of floral traits,pollen morphology,and pollen viability in the male hybrid progeny was conducted to evaluate their diversity and potential as effective pollinators in kiwifruit production.The results revealed substantial phenotypic variation among the hybrid male offspring.The coefficient of variation for petal characteristics was relatively low,whereas other traits such as anther count,flower bud count,tissue proportion,pollen integrity rate,and pollen germination rate exhibited greater variability.Although uniform morphology of normal pollen grains across strains,significant differences in pollen distortion rates were observed.A significant positive correlation was observed between pollen-integrity and pollen-germination rates.Among the evaluated hybrid strains,strain 1 and strain 4 were identified as the most promising candidates for breeding high-quality male kiwifruit varieties.The findings provide valuable insights to support hybrid breeding programs aimed at developing elite male kiwifruit varieties.关键词
