Embodiment 1

[0029] A method for selecting and breeding new varieties of super-big ear wheat, comprising the following steps:

[0030] Step 1: Selection of ears and whole ears. According to the determined hybrid combination, select the main stem ears of typical and robust plants in the female parent group. First, use tweezers to remove the base of the ear and the stunted florets at the top of the ear of EF68 super wheat, leaving 10 in the middle of each ear. Then use tweezers to remove the upper floret of the spikelet, leaving only two well-developed florets outside the base;

[0031] Step 2: Detasselling and bagging. When detasseling, use the thumb and middle finger of the left hand to hold the ears of wheat in step 1. Use the index finger to gently press the top of the glumes to separate the glumes. Insert the tweezers into the seams of the glumes with the right hand. While gently tweezing out the three stamens, do not pinch the anthers and bruise the stigma. After detasseling, immediate...

Abstract

The invention belongs to the technical field of crop breeding, and particularly relates to a breeding method of a new ultra-large-ear wheat variety, which comprises the steps of ear selection and arrangement, castration and bagging, pollination and the like, and can improve the outcrossing rate, improve the breeding efficiency and promote gene recombination between varieties, thereby breeding high-quality wheat. The method is suitable for breeding new wheat varieties in Anhui, Hebei, Henan and Shandong regions, the high yield of the wheat varieties can be obviously improved, the high-yield, short-stem, large-ear, lodging-resistant and high-quality new wheat varieties can be bred, the bred varieties can be popularized and planted in Anhui, Hebei, Henan and Shandong regions, and the popularization range of the wheat varieties is greatly widened.

Description

technical field [0001] The invention relates to the technical field of crop breeding, in particular to a breeding method for a new variety of super-large ear wheat. Background technique [0002] According to the National Bureau of Statistics, the average yield of wheat per mu in my country was 48.8 kg in 1952. By 2008, the average yield per mu had reached 317.5 kg, an increase of 6.5 times. Since the founding of New China 60 years ago, my country's wheat breeding has made remarkable achievements. Thousands of fine varieties have been selected and bred successively. There are 300-400 wheat varieties planted in production every year. There are more than 60 varieties with a planting area of ​​more than 10 million mu, which have made great contributions to the development of my country's wheat production. [0003] In the early days of the founding of the People's Republic of my country, the improvement of wheat varieties in our country started from the selection of local variet...
