Abstract
The present invention discloses a method for breeding corn seeds with high resistance, stable yield and good quality. In a corn field sown with 78599, 78599 variant strains are selected to be used as a female parent, and dan 340 is selected to be used as male parent hybridization to cultivate 974, 986 and 998 which are good varieties having the advantages of high drought prevention, hysteresis prevention, disease prevention, phralidid caterpiller prevention, lodging prevention, stable yield and good quality. After the varieties are experimentally planted for several years, a successful good variety is obtained.
Description
Technical field
The present invention relates to the method for crop seeds hybridization, particularly a kind of corn seed selection.
Background technology
At present, the corn seed of China's sowing, generally all have the characteristics of high yield, all have independent characteristics but each kind can go up in high resistance,, have the performance of drought resisting, waterlogging-resistant, disease-resistant, stable yields as red 413 corn kinds, the windproof ability is just weaker, the conventional corn seed all will have favourable weather (for the crops), and the environment of fertile soil just can obtain high yield.Also exist a large amount of droughts, waterlogging, barren soil at present in China, make the per mu yield of corn can not reach satisfied effect, even go back particle and do not receive.
Summary of the invention
The corn seed selection that the purpose of this invention is to provide a kind of high anti-, stable yields, high-quality is described below:
A kind of corn seed selection is characterized in that:
1, in the corn field of sowing 78599, the suitable arid climate of meeting is met former pinta again and is infected, and causes the death of large tracts of land corn, and in 78599 inbred line plant of only survival, selecting the plant of drought resisting and inheritance stability is the parent;
2, with the drought resisting disease-resistant maize parental seed of seed selection, sowing Dan Fan, just meet typhoon at Dan Fanzhong, the rain imperial palace stagnates, other corns around parental maize, all suffer a body lodging, the result of the serious underproduction, and not lodging of parental maize, well developed root system, aerial root can reach 3-4 joint on the ground, and output does not subtract;
3, the seed selection parent is maternal, select red 340 be paternal hybrid, cultivate 974,986,998 3 kinds, all have the improved seeds of highly drought resisting, waterlogging-resistant, disease resistance, anti-snout moth's larva, resistant to lodging, stable yields, high-quality, this kind after in a few years planting experimentally, the improved seeds of achieving success.
Characteristics of the present invention are: drought resisting: under 40 they conditions that do not have to rain, other corn underproduction 70% are in this kind underproduction 20% of hillock kind; Waterlogging-resistant: when the soaked two weeks of ridge ditch, the underproduction is not obvious; Disease resistance, after typhoon, snout moth's larva is taken place year, the general corn rate 60-70% that fractures, the red 413 rate 20-30% that fracture, the kind rate of fractureing of this invention cultivation is no more than 5%; Resistant to lodging: when typhoon comes, generally all lodge, the corn of this kind is lodging not; Can reach more than 500 kilograms/mu in the above-mentioned disaster output of this kind later; High-quality: this kind contains albumen, starch, cutin than higher.
Embodiment
Embodiment:
A kind of corn seed selection:
In the corn field of sowing 78599, the suitable dry climate of meeting is met former spot again and is infected, and causes the death of large tracts of land corn, and in 78599 inbred line plant of only survival, selecting the corn of stable yields is parental seed;
With the drought resisting disease-resistant maize parental seed of seed selection, sowing Dan Fan just meets typhoon at Dan Fanzhong, the big waterlogging of rain, other corns around parental maize all suffer a body lodging, the result of the serious underproduction, and not lodging of parental maize, well developed root system, aerial root can reach 3-4 joint on the ground, and output does not subtract;
The seed selection parent is maternal, select red 340 be paternal hybrid, cultivate 974,986,998 3 kinds, all have the improved seeds of height drought resisting, anti-stagnant, disease resistance, anti-snout moth's larva, resistant to lodging, stable yields, high-quality, this kind after in a few years planting experimentally, the improved seeds of achieving success.
Claims (1)
1, a kind of corn seed selection is characterized in that:
