青藏高原区8份老芒麦资源农艺性状与生产性能综合评价
Comprehensive evaluation of agronomic traits and yield of eight Elymus sibiricus varieties in the Qinghai-Tibet Plateau
为了综合评价青藏高原区老芒麦资源的特点,本研究在海晏县开展了8份老芒麦资源的农艺性状与生产性能综合评价试验,分析了不同老芒麦资源的农艺性状和产量性状特征,揭示老芒麦饲草产量的影响因素,采用TOPSIS-多准则决策模型对供试老芒麦资源的各项指标进行综合评价,以期筛选出优质的老芒麦资源。结果表明:2龄时,16-364、17-195植株较高,为108.1和109.0 cm;16-093草层高度最高、单株饲草产量最高,分别为36.8 cm,170.3 g;15-025、17-195分蘖数较多,为123和124枝·株-1。3龄时,17-195植株最高、冠幅最大,分别为122.7 cm、140.8 cm;16-093草层高度最高、单株饲草产量最高,分别为51.8 cm,234.7 g;15-025分蘖数最多,为456枝·株-1。结构方程表明,株高和分蘖数是影响老芒麦饲草产量的关键因子,TOPSIS-多准则决策模型综合评价结果表明,16-093饲草生产性能更高、更稳定,是适宜海北州种植的最佳老芒麦资源,可作为下一步品种选育的亲本材料。
The aim of this research was to comprehensively evaluate the performance of Elymus sibiricus varieties in the Qinghai-Tibet Plateau. The work was conducted in Haiyan County of Qinghai Province, and analyzed the agronomic traits and forage yield characteristics of eight E. sibiricus varieties, using a TOPSIS model to identify superior varieties. In year two, varieties designated 16-364 and 17-195 had greater plant height than other varieties (108.1 and 109.0 cm, respectively), while variety 16-093 had the highest grass height among the tested varieties (36.8 cm) and the greatest forage yield per plant (dry weight) (170.3 g). Varieties 15-025 and 17-195 had the highest tiller numbers (123 and 124 tillers of per plant, respectively). In year 3, variety 17-195 had the greatest plant height and crown breadth (122.7 cm and 140.8 cm, respectively), while variety 16-093 had the greatest grass height and forage yield per plant (51.8 cm and 234.7 g, respectively). Variety 15-025 had the highest tiller numbers (456 tillers per plant). A structural equation model showed that plant height and tiller numbers were key factors affecting E. sibiricus forage yield. The TOPSIS model multivariate evaluation showed that the variety 16-093 ranked highest for forage productivity and stability, making it a suitable variety for cultivation in the study region. Therefore, variety 16-093 could be used as parent material for new variety breeding as a next step.
