青藏高原16个青稞品种区域试验甘孜试点结果初报

Assessment of the Adaptability of 16 Hulless Barley Varieties to a highland of Qinghai-Tibetan Plateau Using a Regional Trial at the Ganzi Pilot Test Site

为选育适应青藏高原地区种植的青稞新品种,2010—2012年在四川甘孜对16个青稞参试品种(系)进行了区域试验。结果表明,在16个参试品种(系)中,康青8号、康青7号、甘青5号、藏青25、藏青690、昆仑13这6个青稞品种比对照品种813增产显著,且综合农艺性状好,可在甘孜州青稞适宜种植区种植。其余品种(系)与对照品种813相比,产量相当或减产,可作为种质资源利用或保存。

In order to breed new hulless barley varieties suitable for cultivation in the region of Qinghai- Tibetan Plateau,a regional trial was carried out to evaluate the performance of 16 hulless barley varieties（ or lines） in Ganzi highland,Sichuan Province in 2010-2012. Compared with the control variety 813,six out of the 16 tested hulless barley varieties（ Kangqing8,Kangqing 7,Ganqing 5,Zangqing 25,Zangqing 690,and Kunlun 13） all achieved a significantly greater yield and showed good agronomic characters in general;therefore,they are suitable for planting in the region of Qinghai- Tibetan Plateau. On the other side,the rest varieties（ or lines） produced a similar or even lower yield compared with the control variety 813; thus they may be used or preserved as a source of hulless barley germplasm.
