摘要:

【目的】 研究大麦新品种蒙啤麦5号生产应用价值,为其大面积推广应用提供有利数据支撑。【方法】 利用蒙啤麦5号多年多点区域试验及生产试验数据,采用比较分析法、高稳系数法、基因型分组法以及适应性参数法分析其丰产稳产及适应性,并结合产量相关性状通径分析研究产量要素间相关关系。【结果】 在生产示范中,蒙啤麦5号平均产量4 395.2 kg/hm2,较对照平均增产19.5%,增产点率达87.5%;在两年区域试验中,高稳系数最大,变异系数最小,适应性参数小于1,千粒重为53.8 g,饱满粒93.45%,发芽率为98%,麦芽浸出物80%,库尔巴哈值40.5%,糖化力435 WK,α-氨基酸153 mg/100g;在产量构成因素中,单株粒数(0.667)对产量直接影响最大,其次为有效穗数(0.543)及千粒重(-0.41),单株粒数及有效穗数对蒙啤麦5号产量形成具有正向效应,而千粒重对产量形成具有负向效应。【结论】 蒙啤麦5号丰产稳产性好、适应性强,品质指标达到国家优质啤酒大麦标准,适宜在内蒙古中东西部及生态条件相类似的春麦区推广种植,生产应用中应尽量增加基本苗,但要注意栽培密度以防倒伏,在分蘖期及时施肥浇水促进有效分蘖增多。

Abstract:

【Objective】 To systematically understand the production and application value of new barley variety Mengpimai 5 in the hope of providing favorable data support for its wide application.【Methods】 Based on the multi-point regional test and production test data of Mengpimai 5 for many years,the high and stable yield and adaptability of Mengpimai 5 were analyzed by comparative analysis,high stability coefficient method,genotype grouping method and adaptive parameter method,and the correlation between yield factors was clarified by combining with the path analysis of yield related traits. 【Results】 In the production demonstration,the average yield of Mengpimai 5 was 4,395.2 kg/hm2,which was 19.5% higher than that of the control,and the yield point rate was 87.5%. In the two-year regional test, the high stability coefficient was the largest,the coefficient of variation was the smallest,the adaptive parameters were less than 1,the 1000-grain weight was 53.8 g,the full grain was 93.45%,the germination rate was 98%,the malt extract was 80%,the Kurbaha value was 40.5%,the saccharifying power was 435 WK,and the α-amino acid was 153 mg/100g. Among the yield components, grain number per plant(0.667) had the greatest direct impact on yield,followed by effective panicle number(0.543) and 1,000-grain weight(-0.41). Grain number per plant and effective panicle number had a positive effect on yield formation of Mengpimai 5,while 1,000-grain weight had a negative effect on yield formation.【Conclusion】 Mengpimai 5 has high and stable yield,strong adaptability, and its quality index meets the national standard of high-quality malting barley. It is suitable for planting in the middle-eastern and western Inner Mongolia and spring wheat areas with similar ecological conditions. In order to ensure the maximum yield effect of Mengpimai 5 and promote its large-scale popularization and application,the basic seedlings should be increased as far as possible,but the cultivation density should be paid attention to prevent lodging. At the same time,timely fertilization and irrigation at tillering stage can promote effective tillering.
