Seedling identification method of purity of palmatum leaf pigment gland double labeled hybrid cotton seeds

Abstract

The invention relates to a seedling identification method of the purity of palmatum leaf pigment gland double labeled hybrid cotton seeds, which comprises the following steps of: respectively sowing pigment gland labeled hybrid cotton F1 and male and female parent seeds thereof, and observing the presence and the amount of pigment glands on seedling necks and cotyledon, wherein pigment-glandless seeds are male parent seeds or seeds mixed with other pigment-glandless cotton, seeds with the pigment gland density between male parent seeds and female parent seeds are F1 hybrid seeds, and seeds with higher pigment gland density are female selfing parents or seeds mixed with other multi-pigment gland cotton; and determining the purity of F1 hybrid seeds according to the total number of measured cottonseeds and the quantity of seedlings with male parent, female parent and intermediate type pigment gland characters. The method provided by the invention is simple and easy to implement, fast and reliable, and solves the identification difficult problem of the purity of cotton hybrid seeds. The seed purity can be sampled for inspection at any time in the processes of acquisition, processing, storage, transportation and sale of hybrid cotton seeds according to needs, so that the production quality of the seeds is ensured, and the legitimate rights and interests of producers, sellers and users of the hybrid cotton seeds are protected.

Description

technical field [0001] The invention relates to a method for identifying the purity of agricultural crop seeds, in particular to a method for identifying the purity of seedlings of chicken paw leaf pigment gland (pigment gland) double-marked hybrid cotton seeds. 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 i...
