The selection and breeding of Jinmai 57 was based on its resistance to drought as the main anti-counterfeit guarantee. It was high-stability and high-quality and middle-early-maturing as the breeding target. The characters of complementarity were added to the principle of matching parents to adjust the yield by stabilizing the number of spikes and increasing the grain weight Structure, pay attention to the high photosynthesis of the root and stem leaf spike ideal plant type and source flow physiological coordination of the growth and development characteristics, to ensure comprehensive resistance. To take the early yield assessment, adaptability more than the site identification and selection of appropriate spike sowing density under field density, the whole growth period of systematic observation and other selection methods, so that bred varieties Jinmai 57 showed high and stable yield increased large, drought and anti-greening ability Strong, good quality, good overall agronomic traits.
