Research progress on low temperature tolerance breeding of Cucurbita-ceae crops
Low temperature stress restricts winter cultivation of Cucurbitaceae crops.This review first summarizes the application of selective breeding,introduction,hybridization and heterosis utilization in low temperature tolerance breed-ing of Cucurbitaceae,and lists the current resource libraries for Cucurbitaceae germplasm preserving.Subsequently,the potential roles of heritable variations caused by ploidy breeding and grafting in low temperature tolerance breeding and the current status of genome sequencing in the Cucurbitaceae family were reviewed.Relevant genes or loci responding to low temperature stress were listed,and the latest progresses in gene editing applications for low temperature tolerance research in the Cucurbitaceae family were summarized.Finally,the relevant performances of Cucurbitaceae crops in response to low temperature stress were introduced,which provided reference for the evaluation of low temperature tolerance.
