Embodiment Construction

[0020] Example. Crop male-centered seed production technology. In this technology, the female parent plants are still sown or transplanted into rows, and the male parents are not continuously sown or transplanted into rows or columns, and may not be in the ranks of the female parent plants, but in the center of the female parent.

[0021] The traditional crop seed production (hybrid) production method adopts a determinant method. As shown in Figure 1, the male parents are continuously planted in columns or rows, and the number of male plants is relatively large.

[0022] The arrangement of male parent and female parent of the present invention is shown in Fig. 3. The male parents are discontinuous in rows or columns, with each male parent as the center, and there is a female parent around the male parent whether vertically, horizontally or obliquely. A particular version of this arrangement is shown in Figure 2, which also reduces the number of males by a considerable amoun...

Abstract

A seed preparing technology using male parent as the center of the agricultural crops features that the male parents are sowed in such manner that each male parent must be surrounded by one or more femal parents, so decreasing the number of male parents and increasing the number of female parents and in turn the yield of hybrid seeds.

Description

technical field [0001] The invention relates to a seed production technology of crop hybrids. Background technique [0002] The traditional crop seed production (hybrid) production adopts the determinant, that is, the male parent and the female parent are planted in different rows, and the ratio of the number of rows between the male parent and the female parent varies according to different crops, different fathers and female parents. For example, the ratio of the male parent to the female parent is 1:2, 1:3, 1:4, 2:3, 2:4 and so on. The biggest disadvantage of this method is that the male parent occupies a larger area, which affects the basic seedling number per mu of the female parent, thereby affecting the yield of hybrids. Contents of the invention [0003] The object of the present invention is to provide a male-centered seed production technology for crops. By changing the planting method of the male parent, it reduces the number of male plants and increases the n...
