Comprehensive observation and evaluation of seven excellent wild bramble germplasms.that widely distributed in Sichuan prinvice was conducted lite results showed that the seven elected bramble excellent wild germplasms each had advantages and disadvantages. Compared with those introduced cultivare,7 wild germplasms had lighter weight. The prominent character of R. Setchuenensis was no-thorn. R. Corchorifolius had good fruit quality,but no good yield. R. Conanus and R. Ellipticus var. Obcordatu had good fruit quality and productivity, but both were easy to be affected by genrtplasm diversity and inhabits. R. Lambatianus var. Glaber had abundant Vc.so R. Lambertianus var. Glaber was suitable to be processed into beverage and wine. ITS content of Rubus niveus Thunbup arrived at 14 % , but had poor juice yield duing to too much seeds in fruits. R. Panifolius had good fruit quality and productivity, but its seeds were small. The fruit flavor, yield and adaptability of Rubus conanus, R. Dlipticus var. Obcordatu, Rubus niveus Thunb and R. Parvifotius linn, were superior to those introduced cultivare.%对四川广泛分布的有果用育种潜力的7个优良树莓野生种质进行了较全面的调查研究.结果表明,7个优良树莓野生种质各有优缺点.与栽培品种相比,所有种质的平均单果重偏轻.川莓的突出性状是无刺；山莓果实品质优良,但丰产性差；果实品质优良同时丰产性好的种质是插田泡和栽秧泡,但受种质多样性及所处的生境影响较大；光滑高粱泡果实品质偏酸,但Vc含量高,结合前人报道SOD和鞣化酸含量高,适合加工制成饮料或果酒；红泡刺藤可溶固形物含量高,达到14％,丰产性也好,但出汁率低,种子数量极多；而茅莓果实品质较好,极丰产.从果实鲜食风味、丰产性和适应性来说,空心莓组的5个种质中除山莓不丰产外,插田泡、栽秧泡、红泡刺藤和茅莓均优于我们引进的树莓种群品种.
