Abstract

The invention relates to a method for improving the breeding selection efficiency of waxy wheat. The method is characterized in that a purple and blue waxy wheat strain is rapidly bred and identifiedby the aid of double cross or convergent cross, iodine solution dyeing and positive and inverse backcross technological means, and a purple and blue waxy wheat novel germplasm resource rich in 14 anthocyanins and amylopectin is created. The method is applicable to polymerization of waxy genes (wx-A1, wx-B1 and wx-D1), purple genes (Pk1 and Pk2) and blue genes (Ba or Bk) positioned on different chromosomes of wheat 7AS, 4AL, 7DS, 3A, 7B, 4B and the like, the purple and blue waxy wheat is created and cultivated, the healthcare value and nutritional quality of the wheat are improved, and the requirements of the market for healthy and nutritional green wheat products are met.

Description

technical field [0001] The invention relates to a method for rapid breeding and identification of purple-blue two-color waxy wheat, which belongs to the technical field of wheat genetics and breeding, and specifically relates to a method for rapid selection and identification of purple-blue two-color waxy wheat by double crossing or polymerization hybridization and forward and reverse backcrossing Wheat approach. Background technique [0002] Wheat grains have red, white, purple and blue colors. Purple wheat and blue wheat are different from ordinary wheat grains, also known as colored wheat, because they are rich in 14 species that can remove free radicals in the body, improve immunity and inhibit cancer. Important health care flavonoid anthocyanins have become precious germplasm resources. Blue-grained wheat is rich in 9 kinds of blue anthocyanins, including delphinidin anthocyanins, and purple-grained wheat is rich in 7-9 kinds of purple anthocyanins, including cyanidin ...
