| Abstract: | Founder parents of 260 approved rice cultivars in Heilongjiang Province and pedigree of bred cultivars after 1990s were analyzed.The results showed that founder parents of bred cultivars before 1990s were Shishoubaimao,Nonglin11,Xiayi,cultivars bred or derivative from them accounted for 83.3% in the same period cultivars.The core founder parent was Shishoubaimao,cultivars bred or derivative from it,which accounted for 44.1% in the same period of the total cultivars.Founder parents of bred cultivars after 1990s were Tengxi138,Shangyu397,Fushiguang,cultivars bred or derivative from them which accounted for 62.0% in the same period cultivars.The core founder parent was Tengxi138,cultivars bred or derivative from it which accounted for 24.7% in the same period of the total cultivars. |
