Research progress on protection and utilization of Carica papaya germplasm resources in China
The collection,breeding and application of processing and fresh Carica papaya varieties in China,the research progress of Carica papaya germplasm preservation technology such as seed and germplasm nursery,ultra-low temperature and tissue culture,and the research progress of Carica papaya breeding technology such as traditional hybridization breeding,introduction and domestication,mutagenesis,breeding,cell engineering breeding,genetic engineering breeding and molecular marker-assisted breeding were described.It is proposed that ultra-dry storage can be used as a research direction of Carica papaya seed preservation technology,and the breeding direction of combining traditional hybrid breeding with polyploid breeding,space breeding,molecular module design breeding and other new breeding technologies.
