[0038] 1. Taking the low-glutenin rice variety W3660 as the female parent and Zhendao 88 as the male parent, the hybrid offspring were self-crossed. From F1, the whole protein of the offspring seeds was subjected to sodium dodecyl sulfonate denaturation-polyacrylamide coagulation. Gel electrophoresis (SDS-PAGE) analysis showed that low glutenin and high prolamin traits were always found together; F 1 The seeds were all characterized by low gluten and high prolamin content ( figure 2 ); F 2 The ratio of low gluten and normal protein traits in seeds is about 3:1 ( image 3 ); measure F 3 Seed protein, the segregation ratio of its low-gluten homozygous, heterozygous and normal type conforms to F 2 Plant genotype 1:2:1 ( Figure 4). indicate that the low gluten and high prolamin traits are controlled by a single dominant gene ( image 3 ), and can be stably passed on to offspring.
[0039] 2. Crossbreed with W3660 as the female parent and Zhendao 88 as the male parent. 2 ...
