2006—2007年小麦新品系选拔试验

Screening Test of New Wheat Lines in 2006-2007

通过对36份小麦品系比较试验,调查了小麦的株高、有效穗数、成熟期、穗长、结实小穗、实粒数、单穗重、千粒重等性状,并进行了聚类分析。结果表明:36份品系可分成5种类型,第1种为粒少、低产类型;第2种为穗少、低产类型;第3种为粒多、穗多、高产类型;第4种为穗多、粒多、粒大、高产类型;第5种为晚熟类型。

In the comparative experiment of 36 strains of wheat,the wheat plant height,effective heading,maturity,Spike length,seeded spikelet,grain number, grain weight per panicle,thousand-grain weight and other traits were investigated and cluster analyzed.The results showed that： 36 strains can be divided into five kinds of types. The first type is few grain and low output;the second type is few heading and low output; the third type is many grain, many heading and high yield;the forth is many heading, many grain, big grain and high output;the fifth type is late-ripening.
