Whole Genome Selection of Eight Fruit Traits in Pear (Pyrus spp)
Published:31 May2023 Source:Horticultural Plant Journal
Pear (Pyrus spp), a tree plant of the Pyrus genus in the family of Rosaceae. The cultivation area and yield of pears in China account for about 70% of the world's total, occupying an important position in the world's pear production.
At present, there have been many studies and applications of whole genome selection strategies in crop breeding, but there is still a lack of evidence on how to effectively carry out whole genome selection in pears. To explore the factors that affect the accuracy of pear genome wide selection, this study conducted a systematic comparative study of parameters, in order to provide references for the application of pear genome wide selection breeding.
Whole genome selection can effectively shorten the crop breeding cycle and improve breeding efficiency. This study is the first to explore the effects of the number of SNP molecular markers and the size of the training population on the accuracy of whole genome selection prediction on pears, as well as the impact of different prediction methods on prediction accuracy.
