Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] see Figure 1-2 As shown, the present invention is a corn hybridization method, and the corn hybridization method includes parental inbred line selection, hybrid planting method, parental reproduction method, and cultivation management.

[0037] The parental inbred lines are divided into the female parent inbred line L297 and the male parent inbred line L91; the female parent inbred line L297 is a hybrid of the inbred line L216 and the inbred line L117, which is self-bred ac...

Abstract

The invention discloses a corn hybridization method, and relates to the technical field of agricultural planting. The corn hybridization method comprises parent selfing line breeding, a hybridization planting mode, a parent breeding mode and cultivation management, wherein the parent selfing line breeding comprises a female parent selfing line L297 and a male parent selfing line L91, the female parent selfing line L297 is obtained by hybridizing a selfing line L216 and a selfing line L117 and then carrying out continuous multi-generation selfing separation according to a pedigree method, and a new corn inbred line with stable and uniform plant morphology and agronomic traits is selected. By means of the hybridization mode, high-quality Wanyu 17 is cultivated, so that corn is high and stable in yield, high in reverse folding resistance, high in seed production rate, wide in adaptability, high in volume weight and high in starch content; and by integrating disease resistance identification results of two years, the variety can resist (MR) fusarium stem rot, southern leaf blight, fusarium ear rot, curvularia leaf spot, gall smut and southern rust disease, so that the disease resistance is better.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, in particular to a corn hybridization method. Background technique [0002] Maize is one of the earliest and most widely used crops in agricultural production. For a long time, the use of heterosis in crops has become an important measure to increase the yield and improve the quality of maize. The hybrids selected in my country in the past 20 years, Most of its parental inbred lines come from the four lines of Lancaster, Reid Huangmaya, Luda Honggu and Tang Sipingtou. There are no characteristics in terms of traits or yield, and it is difficult to make a major breakthrough. In order to better meet the growing food needs of the Chinese population, there are a large number of existing corns with low yield, poor resistance to setbacks, and seed yield rate. Low, low adaptability, low bulk density, low disease resistance. Contents of the invention [0003] The purpose of the present inv...
