Application of SnRK1a1 gene in adjusting corn kernel traits and balancing corn yield and quality

The invention discloses an application of a SnRK1a1 gene in regulation of corn kernel traits and balance of corn yield and quality. The SnRK1a1 gene is knocked out, so that the yield and the quality can be balanced, the phenomenon that the yield and the quality are incompatible in the breeding process is broken through, meanwhile, the biomass can be increased, and the growth period can be shortened. 本发明公开了SnRK1a1基因在调节玉米籽粒性状、平衡玉米产量和品质中的用途。本发明通过敲除SnRK1a1基因，发现不仅可平衡产量和品质，打破育种过程中产量和品质不兼容现象，同时还可以提高生物量和缩短生育期。
