Abstract:

Based on the shortage of artificial forage in Ali area, nineteen oat varieties were assessed. Nutritional traits and agronomic 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 Baler 2 had the highest hay yield (7 086.49kg/ha), the highest flag leaf length (23.87cm) and the highest RFQ (243.72), Qinghai 444 was the highest flag leaf width (13.54mm) and the highest stem diameter (10.00mm), Everleaf had the highest leaf and stem ratio (0.87), Souris was the best in plant height (99.71cm). The ranges of tiller number, spike length, spike width, spikelet number, spikelet weight, crude protein and ether extract contents of different varieties were 2.2-3.3, 10.30-30.99cm, 1.83-9.99cm, 0.43-1.21g, 2.3-6.5, 1.68%-3.20% and 5.00%-7.35%, respectively. The grey relational analysis results showed that Baler 2, Monida, Baiyan No.7 and Forage plus were more suitable for planting in Ali region.

Key words: Ali, Oat, Grey correlation analysis, Comprehensive evaluation
