15个谷子品种在宁夏4个区域的适应性鉴定与筛选

Assessment and Screening of 15 Millet Varieties for Adaptability in Four Areas of Ningxia Hui Autonomous Region

为解决宁夏谷子生产中存在品种混杂与选种盲目等问题,采用随机区组试验设计,在宁夏不同生态区域引进15个优良谷子品种,通过田间种植鉴定与室内分析化验,对不同品种的生育期、株高、穗部性状和产量等进行比较分析,从中筛选出适宜宁夏不同生态区域种植的优势谷子品种5个,其中头营为陇谷11号、大同29号、晋谷13号、晋谷25号和晋谷40号;西吉为陇谷11号、陇谷13号、晋谷40号、黑谷子和黄金谷;同心为晋谷29号、济谷12号、晋谷22号、晋谷40号和陇谷11号;盐池为晋谷13号、大同29号、晋谷25号、晋谷29号和黄金谷。

Aiming at resolving the problems existing in millet production in Ningxia Hui Autonomous region( Ningxia),China,which include varietal admixture and the indiscriminate adoption of millet varieties,we performed a field trial to evaluate 15 high- quality millet varieties for their field performance in four different ecological areas in Ningxia. A randomized block design was used in the trial.A number of growth and yield parameters were measured and analyzed for these varieties,consisting of growth period,plant height,panicle traits,and yield. By comparing the parameters of the 15 varieties planted in the four ecological areas,we identified five millet varieties that outperformed the others in each area,which varied with the specific ecological area involved. Specifically,the five varieties suitable for planting in Touying area are Longgu 11,Datong 29,Jingu 13,Jingu 25,and Jingu 40. The five for Xiji area are Longgu 11,Longgu 13,Jingu 40,Black Millet,and Gold Millet. The five for Tongxin area are Jingu 29,Jigu 12,Jingu 22,Jingu 40,and Longgu 11. The five for Yanchi area are Jingu 13,Datong 29,Jingu 25,Jingu 29,and Gold Millet.
