| Abstract: | New mutational rice lines were screened out by conventional intercrossing and radiation mutation breeding,and the targeted characteristics were selected under the extreme environmental conditions of cold damage and in heavy rice blast break-out areas,to breed new highly cold-resistant restoring line hybrid rice,provide high quality restoring line resources for hybrid rice breeding,hybrid rice production,and improve the stress resistance hybrid rice breeding in Guizhou.The result indicated that the restoring... |
