据以往报道,黑海偃麦草(Etytrigia pontica(Podp.)Holub, 2n=10X=70)高度耐盐.美国和以色列的学者Jan Dvorák等人试图将它的这一特性渗入普通小麦(2n=6X=42)中.他们利用耐盐性良好的三个小麦新材料PI 322279、PI 322280和PI 178704(均来自Kharchia)作母本,与偃麦草杂交,产生了大量的衍生杂种.其中多数为非整十倍体或整十倍体,少数为非整八倍体或整八倍体,非整六倍体或整六倍体.经过抗盐性鉴定,八倍体和十
It has been previously reported that salt tolerance is high in Etytrigia pontica (Podp. Holub, 2n = 10X = 70). Jan Dvorák et al., A scholar in the United States and Israel, attempted to infiltrate this characteristic into common wheat (2n = 6X = 42), using three new wheat materials PI 322279, PI 322280, and PI 178704 (all from Kharchia) with good salt tolerance as their female parent, crossed with the Agropyron to produce a large number of derivative hybrids, most of which were non-whole Ten-fold or ten-fold body, a small number of non-octagonal or octagonal, non-whole hexaploid or whole hexaploid. After salt resistance identification, octoploid and ten
