摘　　要：小麦品种“绵阳２１号”和“汉源小麦”及其６０ＣＯ—γ一代（γ１）等四个材料的的干种子经Ｎ２和Ｈｅ—Ｎｅ激光辐照后，对Ｌ２代单株籽粒产量等４３个性状分为产量性状，穗部性状、籽粒性状、生理性状、生育期性状、茎秆性状和分蘖性状等８个组进行典型相关分析，结果表明性状组间相关紧密，其中起主要关联作用的性状是单株生物产量、单株籽粒产量、叶绿素ａ含量、抽穗期、旗叶基角、株高、穗长、结实小穗数和有效分蘖数等。Dry seeds of wheat cultivars'Mianyang 21'and'Hanyuan 'and their r 1 offsprings were exposed to HeNe laser and N 2Laser at two dosage levels separately.A randomized complete block design of three replications was adopted. The 43 characters of the L 2 were divided into 8 groups,including physiological characters.growth stages ect.Canonical correlations were analysed.The relationship among the 8 character groups was inseparable.The following characters played important rales in assoceation of any two character groups:biomass/plant,grain weight/plant,content of chlorophyll,flay leaf length,flag leaf angle,plant height,eat length,filled spikelet number and effective tiller number.
