Problems solved by technology

However, due to the increase of the breeding generation and the increase of the use time of the inbred line, there will be phenomena such as weakened vitality, reduced disease resistance, and reduced reproductive output, resulting in poor disease resistance and low yield of the hybrids at the allocation place.

Embodiment Construction

[0018] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as figure 1 As shown, the embodiment of the present invention provides a method for breeding dwarf maize inbred line 13H280, comprising the following steps:

[0020] Step 1: In the first spring, use (08H67-1×07092)×Zheng 58 to form the basic material to obtain S0, and obtain S1 after self-pollination until the corn is mature and harvested;

[0021] Step 2: Select rows and plants in the first winter (Hainan), and obtain S2 after self-pollination and corn ripening;

[0022] The third step: in the spring of the second year (Shanxi), select rows and plants, and wait for self-pollination to obtain S3 after corn maturity and harvest;

Abstract

The invention discloses a breeding method of a dwarf corn selfing line 13H280. A basic material is built through (08H67-1*07092)* Zheng 58 group to obtain S0; S1 is obtained after the selfing pollinating until the corn mature harvesting; then, line selection and strain selection selfing is continuously performed for four generations; in the generation S4, 10 strains are selected to be subjected to selfing at 6 o'clock in the afternoon on the last day; before 7 o'clock in the morning on the second day, a prepared 0.05 percent EMS solution is dripped to the flat opening part on the top of female ears until the solution does not seep; after one hour, the solution is repeatedly dripped once; in the autumn, seeds of 10 harvested ears are mixed; in the year, the dibbled planting is performed in Hainan according to the planting density being 120,000 strains/hectare for 0.03 hectare; dwarf plants are found in the group for selfing; during the planting in the second year, the harvested plants have the stable inherited characters, the dwarfing is realized, and 13H280 is obtained. The corn selfing line 13H280 obtained by the method has the advantages of fertilizer and water resistance, good drought-enduring performance, compact strains and strong falling resistant capability.

Description

technical field [0001] The invention relates to the field of crop breeding, in particular to a method for breeding dwarf maize inbred line 13H280. Background technique [0002] Maize inbred lines are the basis for the use of hybrid vigor and the preparation of hybrids in maize. Maize has corresponding adaptability to the environment. To prepare maize hybrids with high yield, high quality, multi-resistance and wide adaptability, breeding inbred lines with excellent genetic characteristics is the key work. However, due to the increase of breeding generations and the increase of age of use of inbred lines, there will be phenomena such as weakened vitality, reduced disease resistance, and reduced reproductive yield, resulting in poor disease resistance and low yield of hybrids at the allocation location. Therefore, there is an urgent need to breed new maize inbred lines in agricultural production to meet the needs of new hybrids. Contents of the invention [0003] The object...
