Problems solved by technology

In recent years, due to the climbing stage of conventional wheat breeding in my country, no major breakthroughs have been made in the breeding of new varieties
Utilizing the first generation of hybrid vigor is a common development trend in the breeding of various crops. People hope to use the heterosis of wheat to greatly increase the yield of wheat. However, there has been no report on the use of branched wheat to carry out sexual hybridization to breed new varieties.

Embodiment Construction

[0032] In 2001-2002, Mimai No. 3 was tested in Dingwu Township and Kongzhen Township. The comparison varieties included Jinan No. 17, Lumai No. 23 and No. 54368; About 70 kg of calcium superphosphate per mu, 10 kg of potassium sulfate, 30 kg of ammonium sulfate, and 4,000 kg of soil and miscellaneous fertilizers, 3,000 kg of soil and miscellaneous fertilizers per mu of 6.2 mu (red soil for alkali) in Kongzhen Town, the United States Ammonium 25 kg, potassium sulfate 10 kg.

[0033] The sowing time is 8 kg per mu in Kongzhen Township in October and 10 kg per mu in Dingwu Township, and 10 kg per mu in Dingwu Township. The distance between the sowing distance and the large row is 20 cm, and the small row is 16.5 cm. , The depth is 3-4 cm, the depth of sowing should be consistent, to reduce the lack of seedlings and broken ridges, which is conducive to individual development.

[0034] After sowing management, seedlings emerge 7 days after sowing, and tillers start 16 days after e...

Abstract

A hybridization method for wheat features that the wheat 'Mi7606(1)' as female parent and the branched wheat '33' as male parent are used for hydridizing and after choosing several times a new variety of hybridized wheat is cultured on the basis of the second generation. Its advantages are high quality, and high stress resistance and reproduction speed.

Description

[0001] Field: [0002] The invention belongs to a method for producing crops, in particular to a method for cross breeding of wheat. Background technique: [0003] Wheat is an important food crop in northern my country. At present, the domestic breeding of fine varieties of wheat is mainly through conventional selection. In recent years, due to the climbing stage of conventional wheat breeding in my country, no major breakthroughs have been made in the breeding of new varieties. The use of first-generation hybrid vigor is a common development trend in crop breeding. People hope to use wheat heterosis to greatly increase wheat yield. However, there is no report on the use of branched wheat for sexual hybridization to breed new varieties. Invention content: [0004] The purpose of the present invention is to provide a method for sexual crossbreeding of branched wheat to produce a branched wheat crossbreeding method with good yield and stress resistance. [0005] The object ...
