Colored hybrid cotton with aubergine leaves and method for identifying purity and trueness of cotton

Abstract

The invention belongs to the field of agricultural breeding and particularly relates to colored hybrid cotton with aubergine leaves and a method for identifying purity and trueness of the cotton. A male parent adopting anti-insect upland cotton of colored cotton 05-77 with aubergine leaves and a female parent adopting anti-insect low gossypol cotton of male sterile line 10-380A are crossbred for seed production so as to obtain hybrid of F1 generation, namely the colored hybrid cotton with aubergine leaves. The colored hybrid cotton with aubergine leaves has the advantages that the purity of the hybrid can be judged directly according to the aubergine leaf character, and the abnormal plants are removed, so that the hybrid vigor can be exerted completely, the color of produced colored cutton is ensured uniform, and the trueness of the hybrid can be judged according to the character separation proportion. Both parents of the hybrid have mark characters, and abnormal plants can be removed from the parents for production of hybrid seeds according to the marked characters, so that the purpose that the color of the colored hybrid cotton is uniform can be achieved, and the purity of the hybrid can be improved at the same time; besides, the trueness of the hybrid can be judged according to the character separation proportion.

Description

technical field [0001] The invention belongs to the field of agricultural breeding, and in particular relates to a color hybrid cotton marked with red leaves and a method for identifying its purity, authenticity and generation. Background technique [0002] The cloth made of natural colored cotton does not need to be dyed, has no chemical dye toxins, is soft and elastic, and the clothes made are durable, wear-resistant, comfortable to wear, and beneficial to human health. Because no dyeing is required, the textile cost can be greatly reduced, and the pollution of the environment by ordinary cotton fabrics can be prevented. Due to these outstanding advantages of colored cotton, it is known as the most potential ecological textile in the international market in the 21st century. [0003] my country started the breeding research of colored cotton in the early 1990s. It started late but developed rapidly. A number of new varieties of colored cotton that passed the examination a...

Problems solved by technology

[0004] Although some progress has been made in the production and breeding of colored cotton, there are still some outstanding shortcomings such as low clothing content, small bolls, poor stress resistance, short fibers, poor strength, and low micronaire value.

In order to overcome the above shortcomings in a short period of time, the method of breeding hybrids is often used to improve the yield and quality of colored cotton by using heterosis. However, due to the lack of obvious marker traits for the currently approved varieties, in the process of seed breeding and seed production, There is no effective identification and control method for the purity of the seeds. On the one hand, the heterosis cannot be fully utilized and utilized. On the other hand, only by waiting for the cotton to open bolls can we distinguish whether there is a mixture, and the color consistency of the produced colored cotton is difficult to guarantee.
