the rice mutant enriched with resistant starch (rs), described as rs111, was induced from the elite hybrid rice restorer line r7954.
从杂交水稻优异恢复系r7954诱变筛选了1个富含抗性淀粉的突变体rs111。
by crossing 8 hybrid rice sterile lines with 12 early hybrid rice restorer lines(cultivars) through incomplete diallel cross(nc ⅱ)design, 96 combinations of early hybrid rice were obtained.
采用8个杂交稻不育系和12个杂交早稻恢复系(品种),通过不完全双列杂交,配制了96个不同杂交早稻组合,研究了杂交早稻亲本及所配杂交早稻组合12个米质性状的配合力效应。
genome dna of hainan oryza meyeriana with high resistance and vigorous growth was extracted, then was transformed into rice restorer r225, r128, r15 by stem injecting.
选取抗性较好且生长旺盛的海南疣粒野生稻,提取其基因组dna,通过穗颈注射法将其导入杂交水稻恢复系r225、r128、r15。
