不同燕麦品种在呼伦贝尔地区的引种适应性评价
Adaptability evaluation of different oat varieties introduced in the Hulunbuir region
摘要
Abstract
In order to select high-quality Avena sativa varieties suitable for cultivation in the Hulunbuir region,eighteen oat germplasm lines were tested for their regional adaptation at this site.Because of spatial variation in the field planting environment at the test site,a randomized complete block test design was adopted.Production performance traits measured for the tested germplasm lines included nutritional quality and agronomic traits.A gray correlation analytical method was used to generate a multivariate trait score for the tested varieties,in order to provide information on adaptability of the tested oat varieties in this region.All tested oat varieties reached maturity,with the crop cycle period ranging from 76 to 109 days.The development of all tested germplasm lines showed a pattern of"slow-fast-slow"growth rate.For the tested oat varieties,the vegetative yield gradually increased till the grain filling stage.The variety Galileo had the highest hay yield(13.18 t·ha-1),followed by Tianyan No.3(12.32 t·ha-1),Baylor(12.25 t·ha-1),these three being significantly higher than other varieties(P<0.05).The heights of Baylor(120 cm)and Tianyan No.3(117 cm)were significantly higher than other oat varieties tested(P<0.05).Fuyan No.1 had the highest fresh∶dry weight(4.98)and Baiyan No.7 had the lowest stem∶leaf(1.74),indicating that these two varieties would have better palatability.Fuyan No.1 had the highest crude protein content(13.46%),and Fuyan No.2 had the lowest neutral detergent fiber and acid detergent fiber contents,indicating enhanced nutritive value for these two cultivars.Grey correlation analysis shows that oats grown in this area should be selected with traits such as high fresh∶dry weight,large leaves,thick stems,high crude protein content,and high vegetative yield.Tianyan No.3,Galileo and Fuyan No.2 were the top-ranked varieties for overall performance and could be promoted as excellent varieties for cultivation in the Hulunbuir region.关键词
