Abstract

The invention provides a SNP molecular marker related to wheat ear germination resistance and its application, and specifically relates to the technical field of genetic breeding. The SNP site corresponds to the C / T base mutation; develop CAPS mark according to SNP molecular mark, and described CAPS mark is named as TaE3, and described TaE3 has the nucleotide sequence as shown in SEQ ID NO.5 or the nucleus as shown in SEQ ID NO.6 nucleotide sequence. CAPS markers are used to identify wheat cultivars resistant to panicle germination. The detection method of the invention is simple and convenient, and can be used for molecular marker assisted breeding of wheat resistance to PHS.

Description

technical field

[0001] The invention belongs to the technical field of wheat genetics and breeding, and in particular relates to a SNP molecular marker related to wheat ear germination resistance and its application.

[0002] technical background

[0003] Wheat ear germination (Pre-harvest Sprouting, PHS) refers to the phenomenon that the wheat grains germinate directly on the wheat ear when it encounters continuous rainy weather before harvesting or is in a high humidity environment for a long time. The occurrence of PHS not only reduces the yield of wheat, but also easily leads to the decline of quality, and even the loss of plant value in severe cases, causing huge economic losses to agricultural production. For example, the storage substances (protein, starch, etc.) in the endosperm of germinated wheat are degraded, and the nutritional quality is degraded; especially, the bread made from germinated wheat has poor elasticity and is not easy to be cut, the color of the stea...
