摘要
通过对神农架及三峡地区22县(市)进行豌豆种质资源考察,搜集种质材料138份,并在武昌进行了田间鉴定。考察、鉴定结果表明,该地区豌豆种质资源丰富,水平分布广泛,垂直分布上限达海拔2000米,且类型多样;据不同方法可分成2个变种、组群或类型。经初步筛选,发现了一些优良种质资源,如高蛋白资源,矮秆资源等。当前对这批资源的利用宜从3方面着手,即提纯复壮综合性状好的地方品种直接用于生产、发展以城郊为主体的蔬菜豌豆生产以及利用优良基因资源促进豌豆育种。性状评价结果,该地区豌豆地方品种的主要性状都不很理想,应尽快改良和更换;相关分析和通径分析,揭示了该地区豌豆资源产量因素间的关系,提出了育种应注意的问题。
Garden pea germplasm resource expedition was made to Shennongjia and Sanxia Region from 1987 to 1989.138germplasm materials were collected during the expedition,and characterized at Wuchang city.Results show that this regionhas rich garden pea germplasm resources with an extensive horizontal distribution.Vertical distribution reaches an altitude of2000meters above sea level.These materials could be classified into two varieties、groups or types according to different tax-onomic methods.Some extraordinary materials,such as“Mamaiwan”with high seed protein content、“Baiwandou”withbig white seed、“Suihongwan”with short stalk and“Shiao wandou”with more pods per plant,have been found throughpreliminary screening。Correlation and path analysis reveale relationships among yield components,and indicate that the se-lection criteria for 100—seed weight and pods per plant should be coordinated well in garden pea breeding。
