Ningmai 36 (test name Ningmai 7342) was bred through sexual hybridization and the modified bulk selection method with Yangmai 20 as a female parent and Ningmai 14 as a male parent,and it developed by Institute of Food Crops,Jiangsu Academy of Agricultural Sciences. The average yield of Ningmai 36 increased by 4.81％ and 5.99％,respectively,compared with the check variety Yangmai 20 in the regional tests and production tests of wheat varieties in Jiangsu Academy of Agricultural Sciences Huainan wheat consortium consisted of institutions and enterprises during 2019-2022.The effective number of spikes was 538.5×104/hm2,kernels per spike was 40.8 and thousand-grain weight was 42.2 g.It had moderate resistance to wheat scab with weak-gluten quality. Correlation analysis showed that the effective spike number had a very significant positive correlation with the yield.The path analysis showed that the effective spike number contributed the most to the yield, grain number per spike was the second,and thousand-grain weight was relatively small. The high yield cultivation techniques of Ningmai 36 should be to focus on the number of effective spike and give consideration to increase the grain number per spike and thousand-grain weight.
