摘　　要：用典型相关分析研究三类型四品种大麦出苗至伸长，伸长至单棱，单梭至二棱，二棱至三联，三联至小花，小花至雌雄蕊，雌雄蕊至药隔，药隔至孕穗，孕穗至抽穗，抽穗至成熟10个生产阶段的天数与有效穗数，实粒数，千粒重，单株粒重。小穗数等产量性状的相互关系。分析结果表明，各品种主要表现在单株粒重与抽穗前的某一发育阶段天数的正相关。The correlations between the duration of 10 development stages (emergence to elongation, elongtion to sigle ridge, single ridge to double ridge, double ridge to triple mound,triple mound to floweret, floweret to pistil - stamen, pistil - stamen to anther partion, anther partion to booting, booting to ear emergence, ear emergence to mature) in treare of days and 5 yield traits (effective panicle number, grain number, 1000 - grain weight, grain weight per plant, earlet number) of 4 varieties of barley have been studid with canonical correlation analysis. The results show that for all varieties there is positive correlation between grains weight,per piant and days of one development period before ear emergence.
