紫苏不同品种的生产比较试验

A Productive Comparative Test of New Four Perilla frutescens Varieties in Guizhou

为促进紫苏新品种选育及推广,在贵州省不同区域对4个紫苏新品(系)进行生产试验,比较不同品种(系)的产量、生育期、农艺学性状、品质性状及抗性表现。结果表明:与当地农家种(CK)相比,参试各品种(系)生育期提早2.6~9.5d,增产16.77~23.88kg/667m2,含油量提高1.28~7.77百分点。各品种/系中,5号的产量最高,生育期最短,a-亚麻酸含量最高,品质及其他农艺学性状均较好,表现优良;2号的含油量高达49.01%,可作为高油紫苏新品系进行培育。

The yield,growth period,agronomic traits,quality and resistance of four P.frutescens varieties are observed at six test sites in Guizhou to promote breeding and population of new P.frutescens varieties.Results:The growth period,yield and oil content of four tested P.frutescens varieties are 2.6~9.5 dearlier,16.77~23.88 kg/667m^2 higher and 1.28~7.77% higher than CK(a local variety)respectively.Zisu 5 has advantages of highest yield,the shortest growth period,the highestα-linolenic acid content,better quality and agronomic traits.Zisu 2 with 49.01% oil content can be used as a new P.frutescens variety for breeding of P.frutescens variety with high oil content.
