本文对浙江省30多年来（60年代以来）不同时期生产上种植的有代表性的二棱大麦品种的主要农艺性状进行了研究．结果表明，籽粒产量平均每10年提高8．11％，经济系数从早期品种的0．461提高到近期品种的0．564，生物产量近期品种低，分蘖成穗率和有效穗数近期品种高，每穗粒数、千粒重、单穗粒重近期品种低，株高趋向矮化、抗倒性增加，最后三叶面积变小，生育期缩短、熟期趋早。
In this paper, the main agronomic traits of representative two-rowed barley cultivars grown in Zhejiang Province for more than 30 years (from the 1960’s onwards) were studied. The results showed that the average grain yield increased by 8.11% every 10 years, the economic coefficient increased from 0.461 to 0.664, the recent bio-yield was low, the rate of tillering to panicles and the number of effective panicles were high , Grains per spike, 1000-grain weight, grain weight per spike recent varieties are low, plant height tends to dwarf, lodging resistance increased, the last three leaf area becomes smaller, growth period shortened, maturity early.
