    摘要:

    青稞是我国青藏高原地区藏族同胞的主要粮食作物,青稞产业健康发展事关藏区的粮食安全和繁荣稳定。青稞秸秆是牦牛的主要饲草来源,因此藏区青稞育种需要同时兼顾粮、草生产。为寻求粮草双高型青稞品种的评价方法,筛选出适宜的优良青稞品种,缓解藏区粮草短缺的问题,本研究选取15个青稞品种,于2020和2021年度在西藏昌都和青海海西主产区开展小区试验,调查生育期及产量相关农艺性状15个,观察系列品种对5种主要病害的田间自然发病表现,并测定15个全株饲用品质指标。通过聚类分析、多重比较分析、主成分分析、灰度关联以及丰产稳产性分析,综合评价青稞品种的农艺性状和全株饲用表现。初步获得了一套完整的青稞品种评价方法,筛选出优质粮草双高型青稞品种1个(甘青9号)、籽粒高产型青稞品种1个(昆仑15号)、青贮型青稞品种2个(康青7号和藏青22)。

    Abstract:

    The hulless barley (locally referred qingke) is the staple food crop in the Qinghai-Tibet Plateau in China, and ensuring its sustainable production is crucial to both food and national security. Since the straw of the hulless barley is of importance in yak feeding, breeding for new varieties showing dual-purpose end-use in grain consumption and forage becomes of interest. In order to establish an evaluation system suitable for hulless barley varieties, this study performed the field trials at two locations (Changdu city of Tibet; Haixi city of Qinghai) for two years (2020 and 2021) to record the performance at 15 agronomic and yield-related traits and the responses to five fungal pathogens. The plants including straw and grains at the milk maturity stage were harvested to measure the feeding quality by quantifying 15 parameters. These datasets were further evaluated by clustering analysis, multiple comparisons, principal component analysis, gray relation analysis and the analysis of productivity and stability. An evaluation method was established for selecting the hulless barley varieties for dual-purpose end-use. With the evaluation criteria, the variety Ganqing 9 was identified suitable for both grain consumption and forage. In addition, Kunlun 15 which had high grain yield production were suggested for grain consumption, and Kangqing 7 and Zangqing 22 which had high biomass and feeding quality were qualified for taking as silage.
