摘要
对69个生姜品种的出苗期、长势、整齐度等进行了田间测定与评价。结果表明,27个品种出苗较早,出苗期集中在播后第4周,3个品种出苗较晚,出苗期集中在播后第6周;出苗整齐度表现集中的有16个品种,不集中的有11个品种;长势强的品种有7个,占10%,长势中等的品种有41个,占60%;苗高整齐的共22个,占32%,中等的共24个,占35%。通过10个性状的相关性分析,选出与产量密切相关的6个性状,分别是长势、苗高整齐度、株高、株幅、分支数和主茎粗。
The seeding stage,growth vigor,uniformity and so on of 69 ginger varieties were detected and evaluated in field. The results showed that 27 varieties sprouted earlier,in the fourth week after sowing,and3 varieties sprouted later,in the sixth week after sowing. Sixteen varieties sprouted intensively while 11 varieties was scattered. Seven ginger varieties had strong growth vigor,accounting for 10%,and 41 ginger varieties had medium growth vigor,accounting for 60%. Twenty-two varieties had uniform seedling height,accounting for 32%,and 24 varieties had medium uniform seedling height,accounting for 35%. Through correlation analysis of 10 characters,6 characters closely related to yield were selected including growth vigor,uniformity of seedling height,plant height,plant width,branch number and main stem diameter.
