【 摘 要 】

The factors that decrease the kernel weight of Hokkaido wheat cultivar “Haruyutaka” in Western Japan were analyzed based on the kernel weight of F1 of the cross with Kyushu cultivar “Daichinominori.” The F1 kernels were obtained by a reciprocal cross between these two cultivars in 2000/2001, 2001/2002 and 2002/2003. The average and variance of the F1 kernel weight were compared with those of the self-pollinating kernels. The F1 kernel ripened on Haruyutaka had almost the same weight as that of the self-pollinated kernel of Haruyutaka in both average value and variance in all three seasons. The F1 kernel ripened on Daichinominori plant had heavier average weights than the self-pollinated Haruyutaka kernels in 2001/2002 and 2002/2003, although not in 2000/2001. These results suggested that the source capacity in Daichinominori is higher than that in Haruyutaka, but it may vary with the season. In addition, it is thought that Haruyutaka has dominant kernel weight-decreasing genes.
