Embodiment 1

[0022] Example 1 Cotton hybrid Biaoza A1 (female YmR 1 ×Paternal Y 2-2 ) production process, in 2007, the Cotton Multi-resistance Breeding Research Office of the Institute of Plant Protection, Henan Academy of Agricultural Sciences conducted a survey of 675 seed-producing households in 5 seed-producing villages of hybrid cotton seed-producing bases in Luyi County and Huaiyang County. Sampling and identification of chicken paw leaves and pigment gland double-marked cotton hybrids. When the hybrids are purchased, random samples are taken from the hybrid cotton seeds sold by each seed producer, and about 100 grams of samples are taken, and the number is counted from the samples. 100 seeds shall be identified according to the following method:

[0023] (1) Randomly sample 100 grains from the retained samples, cut them in half from the middle of the cottonseed with a sharp knife; and randomly select male parents (Y 2-2 ) and maternal (YmR 1 ) 10 seeds each were cut as a control;...

Abstract

The invention relates to a method for identifying the purity of pigment-gland-marked hybrid cotton seeds. The method comprises the steps of: respectively transecting pigment-gland-marked hybrid cotton F1 generation and male parent and female parent seeds; observing the availability or the number of pigment glands; if no pigment gland exists, the seed is are mixed with the male parent seeds or other pigment gland free cotton; if the density of the pigment glands is between the male parent and the female parent seeds, the seed is an F1 generation hybrid seed; if the density of the pigment glands is large, the seed is the female parent selfed seed or is mixed with other poly-pigment gland cotton; and judging the F1 hybrid seed purity according to the total number of tested cotton seeds and the number of cotton seedlings with pigment gland characters as the male parent, the female parent and a middle type. The method is simple and easy to operate, rapid and reliable, solves the identification difficulty of the purity of cotton hybrid seeds. The purity of the hybrid cotton seeds can be sampled and checked according to needs at any time in the processes of purchasing, processing, storing and transporting and marketing so as to guarantee the production quality of the seeds and protect legitimate rights and interests of producers, sellers and users of the hybrid cotton seeds.

Description

technical field [0001] The invention relates to a method for identifying the purity of crop seeds, in particular to a method for identifying the purity of hybrid cotton seeds with pigment gland double-markers. Background technique [0002] With the advancement of science and technology and the development of agricultural production technology, more and more excellent varieties have made significant contributions to high and stable agricultural yields. High-yield, high-quality, and disease-resistant varieties are becoming more and more popular among farmers. Cotton hybrids have excellent traits such as high yield, high quality, insect resistance, and disease resistance. The application of cotton hybrids plays an important role in improving the production level of cotton production in my country. my country's current hybrid cotton planting area is more than 1 million hectares, and more than 90% of the cotton hybrids used in production are selected and bred by artificial emas...
