Benefits of technology

This patented technology allows farmers to collect genetic material from different sources without having to wait until winter months before they can start plantings again. It uses these superior wheat plants carrying genes like those used by bacteria called Bacillus thuringiensis (BT) during this process. By comparing and identifying them, researchers are able to identify better ways to produce crops faster than usual while ensuring their quality remains high throughout its entire lifecycle.

Problems solved by technology

This patents discusses how farmers want to improve crop yields without compromising on other factors like fertility. Current techniques involve selecting specific types of plants based solely upon growing seasonal trends such as long vegetative durability (LV) cycles during winter months when temperatures fall well below 0°C. There may still exist some areas where conventional ways cannot achieve these desired results due to insufficient greenery availability at any given time.

Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with specific embodiments.

[0015] Based on the above reasons, we put forward the breeding of new "sowing date tolerant" wheat varieties from the level of breeding, in order to solve the problems that the sowing date of wheat in the Sichuan Basin and southwest wheat areas cannot be advanced and the yield is difficult to increase. The so-called "permissive sowing date" new wheat variety means that under the climatic and ecological conditions of the Sichuan Basin and Southwest wheat regions, its safe and high-yield sowing date range is much wider than that of the current existing varieties, and it can be sown throughout October , and can obtain high yield (existing wheat varieties can only adapt to sowing from the end of October to the first ten days of November). Of course, the main advantage of the new sowing-date tolerant wheat variety is that its sowing date can be greatly advanced compared with exis

Abstract

The invention discloses a breeding method of a new variety of sowing-period-tolerance-type high-yield wheat. The method comprises the following steps of: A1, widely collecting related germ plasm resources and evaluating the germ plasm resources, namely evaluating the growth and development conditions of the germ plasm resources and confirming whether the germ plasm resources can be sowed in advance and how early the germ plasm resources can be sowed; A, during the collecting and evaluating processes of the germ plasm resources, performing hybridization with the evaluated high-quality wheat strains as core parents to produce more diverse variation types which are good for selection; A 3, repeatedly evaluating and selecting the offsprings produced through hybridization combination in the last step for many years on an early sowing condition and stabilizing the offsprings; and A 4, carrying out line or strain comparison evaluation on selected strains so as to finally breed a variety (line) of sowing-period-tolerance-type high-yield wheat. According to the invention, the safe sowing period of wheat is advanced to a period between early October and late October from a period between late October and early November, the growth period of wheat is prolonged by 20-30 days, the yield per unit area of wheat is improved by 20-30%.
