Wheat cultivar “Haruyutaka” bred in Hokkaido and “Daichinominori” bred in Kyushu and their F1 hybrid were grown in Yamaguchi, and the kernel weight at different positions on the spikes was investigated. Haruyutaka had lighter kernels than Daichinominori at all positions throughout four successive seasons. All kernels in the first, second and third florets of Haruyutaka were lighter than those of Daichinominori, and the third floret kernel was particularly lighter than the first and second floret kernels in Haruyutaka. Daichinominori had heavy kernels even in the third floret in Yamaguchi. F2kernel weight was as heavy as those of Daichinominori and heavier than those of Haruyutaka. Among the F2kernels the third floret kernel was lighter than the first and second floret kernels, while its standard deviation on the third floret was larger than those of the first and second floret kernels. There would not be genetic segregation in F2kernel weight in the first and second florets. © 2014, Crop Science Society of Japan. All rights reserved.
