西瓜染色体易位及少籽西瓜育种研究进展
Research progress on chromosome translocation and breeding of less-seed watermelon
摘要
Abstract
With the improvement of consumption standards,the demand for seedless watermelon has gradually increased.At the diploid level,seedless watermelons are mostly obtained by artificially spraying plant growth regulators onto the pis-til ovaries to induce parthenocarpy,the method cannot be widely implemented under open field conditions.Traditional triploid seedless watermelon,while achieving seedless fruit and suitability for large-scale open field cultivation,suffer from the"three-low"problems:Low seed yield,low germination rate,and low seedling survival rate.Chromosome trans-location less-seed watermelon has significantly reduced seed number,offering both production and cultivation advantag-es,and they enable large-scale,simplified cultivation without the need for auxiliary chemical applications.This paper sys-tematically reviews the research progress on chromosome translocation in watermelon,focus on elucidating recent studies on the generation pathways and mechanisms of chromosome translocation.Additionally,it discusses the current applica-tions and future prospects of chromosome translocation in the breeding of less-seed watermelon.The objective is to pro-pose strategies for the creation of new translocation-based germplasm and the breeding of less-seed watermelon cultivar.关键词
