以水稻广亲和品种为双亲之一配制的15个籼粳杂种及其亲本为材料,测定了碾米、外观、蒸煮和食用品质及蛋白质含量,分析了杂种品质表现的特点及与亲本的关系。灰色关联度分析表明:供试籼粳杂种品质性状均数的综合表现不及汕优03,但有些组合,如鄂宜105/培矮64等的品质表现明显优于对照或与之相当。说明通过适当的亲本选配,可以获得品质比较理想的籼粳杂种。
Fifteen indica-japonica hybrids and their parents were prepared from one of the parents of rice varieties with wide compatibility, and the rice milling, appearance, cooking, edible quality and protein content were determined. The characteristics of hybrid quality and its relationship with parents were analyzed . Gray correlation analysis showed that the composite performance of indica / japonica hybrids was less than that of Shanyou 03, but some combinations such as Eyi 105 / Pei’ai 64 showed better performance than CK or comparable. The results showed that the best quality indica-japonica hybrids could be obtained through appropriate parental matching.
