Embodiment 1

[0065] The hybrid corn seeds used in this example are the hybrid corn variety "Quanyu 1233" and its male parent "512" and female parent "533".

[0066] 1. Material planting

[0067] In April 2021, the male parent "512" and the female parent "533" of "Quanyu 1233" were sown directly at the corn seed production base, and they were planted in two fields (field A and field B, both with an area of ​​2000 square meters) square meters): The male parent "512" was sown on April 17; the female parent "533" was sown on April 15; both parents were planted in the same field (1 row of male parent: 7 rows of female parent), and the distance between rows and plants was 50cm× 19cm. Field A is a control field, and in the process of hybrid seed production, artificial removal of impurities and emasculation methods are used to improve the purity of seed production; Field B is to use the method of the present invention to remove hybrid plants to improve the purity of seed production.

Abstract

The invention relates to a hybrid corn seed production cost-saving, impurity-removing, emasculation and purity-keeping method, which comprises the following steps: adjusting the sowing time according to the planting and growth period characteristics of male parents and female parents and the flowering time of the male parents and the female parents, so that the spinning period of the female parents and the tassel pollination period of the male parents meet; performing abnormal plant identification by using a corn abnormal plant identification model after seed production corn male and female parent final singling, after jointing and before tasseling, and removing abnormal plants; in the female parent tasseling period, identifying tassels by using the corn tassel identification model, and removing the tassels which are extracted; removing tassel plants which are not completely removed in the female parents repeatedly, so that it is ensured that tassels of the female parents are completely removed after tasseling of the female parents and before pollination. In the corn seed production process, the labor intensity of manual impurity removal and female parent emasculation is relieved, influences of human factors are avoided, and the purity of hybrid corn seeds is improved.

Description

technical field [0001] The invention belongs to the field of agricultural technology, in particular to the field of methods for detasseling and pure hybrid corn seed production. Background technique [0002] Maize is one of the most important crops in the world, and it is also the crop with the most successful use of heterosis. Excellent corn hybrids are an important genetic basis for high-yield and high-quality corn. The purity of hybrids is one of the measures of seed quality and an important prerequisite for ensuring the full play of heterosis. Corn is a self-pollinated crop, and castration is a hybrid One of the most important tasks in seed production, so in the process of hybrid corn seed production, it is necessary to strictly remove the hybrids, especially the strict emasculation of the female parent; the purity control of the hybrid seed production field is accompanied by the entire seed production process. Manual removal is still the main way to remove impurities a...
