영문 초록

Intergeneric hybridizations have been carried out between Triticum aestivum cv. Olmil and 4 Thinopyrum species. Premature embryos were obtaind from cross combinations of T aestivum cv. Olmil pollinated with Th. junceum, Th. ponticum and Th. caespitosum, and ratios of premature embryo used for embryo rescue were 3.1%, 2.6% and 1.8%, respectively. In the crosses of Olmil and Th. junceum, 13 hybrids were regenerated by the embryo rescue technique, and fifteen hybrids from the crosses of Olmil and Th. ponticum were also obtained. The hybrids of Olmil(2n=6x=42) and Th. junceum(2n=6x=42) were hexaploid(2n=6x=42) while the hybrids of Olmil(2n=6x=42)×Th. ponticum(2n=10x=70) were octaploid(2n=8x=56), and both hybrids were sterile due to irregular chromosome pairings in meiosis. Agronomic charateristics of these hybrids were intermediate between their parents. Hybrids of Olmil and Th. ponticum can be divided into two groups, annual 4 plants resembling wheat and perenial 11 plants resembling Thinopyrum.
