Özet

The objective of this study was to assess the effect of the genes for long glume (P and P-2) on carbon-isotope discrimination (Delta) and grain yield (GY) using near-isogenic lines of a durum wheat cultivar, LD222 in Japan and Turkey. The location had major effects on variation of Delta and GY, but the effects of glume length on Delta and GY were little in overall environments. It was suggested that the gene P-2 had more adaptive effects than the P gene. The curvilinear relationship between Delta and GY is probably based on the difference between the locations with relatively little genetic variation.
