Breeding method of red-grain early-ripe strong-gluten high-quality wheat

Abstract

The invention belongs to the technical field of crops breeding, and mainly relates to a breeding method of red-grain early-ripe strong-gluten high-quality wheat. The breeding method comprises the following steps: performing primary hybridization by adopting French wheat variety NSA00-0061 as a female parent and LUYUAN202 as a male parent to obtain hybrid seeds; performing secondary hybridization by adopting the hybrid seeds as the female parent and Jimai 22 as the male parent to obtain generation-F1 seeds; and planting and breeding for the generation-F1 seeds. Since the ripe period of NSA00-0061 is 15 days later than the domestic varieties, the filial generation obtained by virtue of the hybridization of NSA00-0061 and Luyuan202 is still late-maturing; and by virtue of the secondary hybridization, the male parent of the secondary hybridization is Jimai 22, so that the mature period of the obtained generation-F1 seeds is shortened to be consistent with the mature period of the domestic wheat varieties. According to the breeding method, subunit 5+10 in the foreign seed varieties is introduced into a domestic material, and the foreign wheat subunit and the domestic wheat variety subunit are successively polymerized, and the polymerization of various subunits enables the wheat variety to have a high quality of strong gluten.

Description

technical field [0001] The invention belongs to the technical field of crop breeding, and mainly relates to a breeding method of red-grained early-maturing, strong-gluten, and high-quality wheat. Background technique [0002] my country is the world's largest wheat producer and consumer, and occupies a pivotal position in the world grain market. Through the efforts of breeders for many years, the yield level of my country's wheat has increased steadily, but there is an obvious gap in the overall level of my country's wheat quality breeding compared with foreign countries. In recent years, with the development of my country's agricultural production, agricultural products have increased, and the commodity rate of wheat has become higher and higher, and urban and rural people have put forward higher and higher requirements for wheat quality. In order to meet the demand for high-quality wheat, my country's wheat imports have accounted for about 1 / 10 of the national wheat suppl...
