Abstract
A disclosed breeding method for high-yield pest-resistant sweet corn comprises the following steps: selecting sweet corn Lvsechaoren and sweet corn Shizhen, respectively performing inbreeding, and then performing hybridization, so as to obtain F1 generation seed; inbreeding the F1 generation seed for 6-8 generations, hybridizing with a common corn inbred line, and selecting out a male parent inbred line by employing a pedigree method; selecting sweet corn Aotian 01 full seed, inbreeding for 4-8 generations to form a female parent inbred line; and hybridizing the male parent inbred line and the female parent inbred line, and obtaining the high-yield pest-resistant sweet corn by using a pedigree method. The high-yield pest-resistant sweet corn bred by the breeding method for the high-yield pest-resistant sweet corn is extremely strong in disease resistance, high in yield and good in mouthfeel.
Description
Technical field
The present invention relates to corn technical field, particularly relate to the selection of the pest-resistant sweet corn of a kind of high yield.
Background technology
Sweet corn is subspecies of corn, compared with conventional corn, it is of high nutritive value, containing the amino acid of needed by human, protein, sugar and multivitamin, and there is good palatability, eat raw and have fruit, the nutrition of vegetables and local flavor concurrently, be easy to features such as chewing and digest and assimilate, along with the raising of people's living standard, diet structure shows by the transformation to nutrition type, health type simply having adequate food and clothing, sweet corn is more and more subject to the favor of people.
Sweet corn is started late in China, and production lacks high yield, disease-resistant improved seeds, and therefore selecting high-quality, high yield, wide adaptability, pest-resistant sweet corn kind is current problem demanding prompt solution in China's extensive use.
Summary of the invention
The present invention proposes the selection of the pest-resistant sweet corn of a kind of high yield, with the sweet corn disease resistance of the method seed selection is extremely strong, output is rich, mouthfeel good.
The present invention proposes the selection of the pest-resistant sweet corn of a kind of high yield, comprise the following steps:
S1, the green superman of selection sweet corn and sweet corn generation treasure single file plantation respectively, and bagging selfing 3-5 is for obtaining green superman's inbred line and the precious inbred line of generation;
S2, precious to the green superman's inbred line in S1 and generation inbred line is carried out manually selected, remove foreign particle, infected seed and flat grain, select the hybridization of the seed of full seed to obtain F1 generation seed;
S3, the F1 generation seed obtained is carried out manually selected, remove foreign particle, infected seed and flat grain, select the F1 generation seed single file plantation also bagging selfing 6-8 generation of full seed, select seed and the conventional corn hybridization between selfed lines of full seed, select male parent inbred line with pedigree method;
The sweet 01 single file plantation of Austria of S4, selection full seed, in bagging selfing 4-8 generation, the seed selecting full seed is maternal inbred line;
S5, by the male parent inbred line in S3 and the maternal hybridization between selfed lines in S4, obtain the pest-resistant sweet corn of described high yield with pedigree method.
Preferably, in S3, described conventional corn selfing be tuck in 478, neat 319, Zheng 58, one in prosperous 7-2.
Preferably, in S3, described conventional corn selfing is prosperous 7-2.
The sweet corn disease resistance of the selection seed selection of the pest-resistant sweet corn of high yield of the present invention is extremely strong, can Chinese People's Anti-Japanese Military and Political College spot, virus, the multiple diseases such as green grass or young crops is withered, line is withered; Output is rich, general per mu yield 800-1000 kilogram; Lodging resistance is strong, and adaptability is good, and product are of fine quality, and sugar content is high, and fringe grain is golden yellow, and tender and crisp aromatic, skin is thin without slag.
