| Abstract: | Having adopted the double crossing method to break up some linkages of unfavorable genes and gathered the good quality, high yield, dry resistance, saltendurance and strong restoring gene, had been bred a keng rice variety --Tianjin 1244 which would adapt to water culture, dry culture and be utilized as a restoring line. This variety had been trial cultivated successfully in Tian-jin, Henan, Shandong etc. Its grain yield had increased by 14.5%, 23.6% under spring dry culture aad after-wheat dry culture conditions, respectively. Its F1 setting percentage was 80.9-93.6% while used as restoring line and grain yield increased by 5-16.5% than check variety Xiuyou 57. |
