Abstract

Abstract:

In order to deeply analyze the comprehensive production performance, high yield potential, and influencing factors of oat varieties in the irrigation area along the Yellow River in Baiyin, the experiment selected 16 indexes of 18 oat varieties (lines) suitable for planting in irrigated fields for gray correlation degree, principal component analysis, correlation, and path analysis. The results showed that among the agronomic traits, the top five correlation coefficients with grain yield were ear number (0.45), 1000-grain weight (0.40), grain weight per plant (0.15), leaf-stem ratio (0.09), and plant height (0.08); The top five correlation coefficients with hay yield were growth period (0.73), plant height (0.60), leaf-stem ratio (0.47), main ear length (0.44), 1000- grain weight (0.43); The top three traits associated with oat seed yield were growth period > 1000-grain weight > single plant grain weight. The top three traits associated with oat hay yield were number of ears > flag leaf length > seedling number. According to the comprehensive judgment, Yinyan 8, Yinyan 6, and Hangyan 1 are appropriate for grain seed type oat varieties, while Dingyan 2 and Yinyan 9 are appropriate for the demonstration, promotion, and application of forage and grass oat varieties.

Key words: Oat, Grain yield, Hay yield, Agronomic traits, Grey correlation degree, Principal component analysis
