对8种引进的美国啤酒大麦及当地主栽甘啤4号品种进行生育期、产量及品质综合比较。结果表明:生育期除MERIT品种外,其余均较对照甘啤4号早熟,株高整体较高,穗长较短,二棱品种分蘖成穗数高;所有参试品种籽粒蛋白质、千粒质量、饱满度、发芽率均达国家优级标准(蛋白质含量10.0%~12.5%、千粒质量≥37g、饱满度≥80%、发芽率≥97%);各品种麦芽的水分、细粉浸出率、α-氨基氮、黏度、糖化力均达到国家优级标准(麦芽水分≤5.0%、细粉浸出率≥79%、α-氨基酸态氮≥150 mg/kg,黏度≤1.60 mPa·s,糖化力≥260 WK)。大麦品种Z090M066M平均产量9 466.31 kg/hm~2,位居参试品种第一位;但参试品种均出现条纹病。综合分析,Z090M066M可以进行进一步试验示范推广。
The comparisons of growth period, yield and quality of 8 introduced American beer barley and local cultivated sweetpotato beer variety No.4 were carried out. The results showed that except for MERIT, all other cultivars were more mature than Ganpao No.4, the whole plant height was higher, the spike length was shorter and the tillering number of two cultivars was higher. All the tested cultivars had the highest protein and grain weight , Plumpness and germination rate reached the national excellent level (protein content 10.0% ~ 12.5%, 1000 grain quality≥37g, plumpness≥80%, germination rate≥97%); the moisture and fine powder leaching rate , Α-amino nitrogen, viscosity and saccharifying power all reached the national excellent level (malt moisture≤5.0%, fine powder leaching rate≥79%, α-amino acid nitrogen≥150 mg / kg, viscosity≤1.60 mPa · s, Force ≥ 260 WK). The average yield of barley variety Z090M066M was 9 466.31 kg / hm ~ 2, ranking the first among the tested varieties. However, the stripe disease appeared in the tested varieties. Comprehensive analysis, Z090M066M can be further experimental demonstrations.
