Abstract

Abstract:

【Objective】 To analyze the genetic diversity relationship of phenotypic traits in forage oat germplasm resources worldwide, conduct Cluster analysis and Comprehensive evaluation, explore excellent materials, and provide Material basis and Technical support for Germplasm creation and Breeding utilization of forage oats. 【Method】 Using 244 collected domestic and foreign forage oat germplasm as experimental materials, they were planted in Guyuan City, Ningxia from 2023 to 2024, and 11 Phenotypic traits including plant height, stem diameter, tiller number, leaf number, leaf length, leaf width, ear length, whorled layers number, number of spikelets, fresh weight, and hay weight were systematically measured. Multiple evaluation methods such as correlation analysis, principal component analysis, membership function, and hierarchical cluster analysis were comprehensively used for multi-dimensional evaluation. 【Result】 Phenotypic variant analysis showed that the coefficient of variation of the 11 traits ranged from 12.11% to 42.69%, among which tiller number, leaf length, and number of spikelets had higher coefficient of variation, which were 42.69%, 32.90%, and 32.77% respectively; The genetic diversity index ranged from 1.408 to 2.077, among which number of spikelets, stem diameter, and hay weight had higher genetic diversity index, which were 2.077, 2.075, and 2.074 respectively; Correlation analysis revealed that there were 41 pairs of significant or extremely significant relationships among the 11 traits, and the indicators with higher correlation with hay weight of forage oats were fresh weight, leaf number, leaf width, whorled layers number, plant height, and number of spikelets in sequence; The principal component analysis showed that the contribution rate of six principal components were extracted, which were 28.980%, 14.833%, 12.494%, 9.556%, 7.495%, and 6.850% in sequence, with the Cumulative contribution rate reaching 80.209%; Hierarchical cluster analysis divided the 244 germplasm resources into 5 Groups. Among them, the germplasm resources in Group Ⅱ had thick stem diameter, long ear length, and many whorled layers number, belonging to lodging-resistant or high yield materials; The germplasm in Group Ⅲ and Ⅳ had high plant height, long leaf length, and many tiller number, belonging to high yield forage materials; The germplasm in Group Ⅴ had multiple leaves, wide Leaf width, many number of spikelets, and high fresh and hay weight, belonging to high-quality forage type and high grain yield materials. The Comprehensive phenotypic evaluation value (F value) of germplasm resources was obtained through analytical methods such as membership function, and 20 accessions of Core germplasm resources with excellent comprehensive traits were screened out. 【Conclusion】 The results revealed that the 244 forage oat germplasm resources possess rich phenotypic genetic variation and diversity; Cluster analysis divided the 244 germplasm resources into 5 different groups, which can be selected and utilized according to the excellent characteristics of different germplasm resources and breeding objectives; 20 accessions of forage oat germplasm resources with excellent comprehensive traits, such as As166, As129, As163, As131 and As80 were screened out using F value.
