Morphologic and cytological characteristics of hybrid F1 between E. canadensis and E. sibidcus were studied. The results showed that hybrid F1 were obviously exceeded parents in plant growth vigor, and spike type of F1 was between parents. The karyotype formula of hybrid F1 which was true hybrid was 2n =4x=16M + 10m +2st. At meiotic anaphase, chromosome lagging behaviors were frequently observed. The frequency of lagging chromosomes of F1 was 87.37%. At meiotic metaphase, there were many univalents and multivalents, and the rod bivalent formed greatly. 展开更多

[ Objective] This study was to explore the inheritance of BC1 F3 to excellent characteristics of parents( Elymus dahuricus, Hordeum brevisubu/atum), heterosis and fertility restoration. E Methodl The agronomic characters such as growth period, growth rate, pollen fertility, fecundity, reproducibility and fresh grass output of Elymus dahudcus, Hordeum brevisubu/atum and BC1 F3 were comparatively studied. E Result l The growth dynamic of the BC1 F3 lined tended to like that of its parent Hordeum brevisubu/atum; although growing periods of various lines were different, they were close to that of Hordeurn brevisubulatum. There were differences in pollen fertility and seed setting, the pollen fertility rate of YF3-93 was higher than recurrent parent Hordeum brevisubulatum, its seed setting rate in open pollination was also higher. Some lines had low pollen fertility rate and seed setting rate, such as the pollen fertility rate of PF3-52. There were significant differences in the output among BC1 F3 lines, e.g. the heterosis (HP) of YF3-64, YF3-74 and YF3-83 were 75.53%, 75.12% and 66.16%, respectively; however, the yields of PF3- 52, PF3-15 and PF3-42 were lower than their parents. ~ Conclusion] This study provided reference for breeding new varieties of forage which is suitable to drought and saline environment. 展开更多
