摘要
以13个美国水稻品种为母本分别与籼稻、粳稻杂交配制了6组p×q不完全双列杂交试验，研究了美国稻的8个性状的一般配合力、特殊配合力、遗传力和显性度等遗传参数。结果表明：同一美国品种在A×H和A×K（不同组合类型）间各性状的配合力及遗传参数均有一定的差异，不同美国品种在同一组合类型中也有一定的差异。
6 p ×q experiments derived from crossing between 13 American rice varieties(A)and Indica or Japonica type. GCA, SCA, Heritability and Dominant degree for 8 charactersin American rice varieties were studied. The results showed that the combining ability andInheritance parameter for 8 characters were defferent between A×H and A × K, and deffer-ent between American rice varieties.
