What seed industry is tk60 1 corn seed? Please briefly introduce it.

The applicants and breeders of tk60 1 maize seeds are Tongliao Academy of Agricultural Sciences and Beijing Academy of Agricultural Sciences Research Center. It was obtained by crossing "Tong 0605 1" as female parent and "Tong TM" as male parent. At present, the application has been passed, and the approval number is Meng Shenyu 20 17003. In the pre-test of 20 14 late-maturing group, the average yield per mu of this variety was 973.3 kg, which was 15.73% higher than that of the control variety. In the regional test of 20 15 late-maturing group, the average yield per mu was 9 10.8 kg, which was 4.2% higher than that of the control variety.
