Abstract:

In order to study suitable forage germplasm for the agro-pasture ecotone of northern Shanxi, fresh and dry (hay) yields, agronomic characters, nutrient content and feeding value of 9 oat varieties were assessed. Three nutritional traits were determined and analyzed by conventional analysis, and the comprehensive evaluation was carried out by grey relational analysis method. The results showed that the yields of fresh and hay of Caoyou No.1, Molasses and Yuanza No.1 were higher from booting stage to flowering stage, and the hay yield of Caoyou No.1 at flowering stage reached 9 000kg/hm 2; Caoyou No.1 had the longest ear (24.56cm); The number of bolls per spike of Molasses was the largest, up to 84.64; the number of grains per spike of Yuanza No.1 (621) was the most; the maximum grain weight per spike of Molasses and Bayou No.18 were 17.16 and 16.28g, respectively (P<0.05); the 1000-grain weight of sweet oat (44.03g) was the largest, and the difference between the other species was significant (P<0.05). The digestible dry matter of varieties changed from 63.62% to 69.05% and dry matter intake from 1.91% to 2.22%; the relative feed value of Baiyan No.2 was the highest, up to 114.89, and no significant difference with sweet oat, but significantly higher than other oat varieties (P<0.05). The comprehensive analysis showed that GL381, Molasses and Sweet oat which were more suitable for planting in this area.
