| Abstract: | The wheat cultivar Luyuan 502 selected from the cross with space mutant 9940168 as female parent and Jimai 19 as male parent after pedigree breeding possessed high and stable yield,disease resistance and wide adaptation.The number of formed spikes stabilized more than 6 000 thousand per hectare;the grain number per spike was over 37 and the 1000-grain weight was over 42 g.It indicated that the three yield components were rational,and germplasm innovation,shuttle breeding and multiple spot identifications could effectively improve the breeding of new wheat variety with high yield and wide adaption. |
