摘　　要：以32份小黑麦品种为试验材料,研究了各品种的产量构成因素(穗长、小穗数,穗粒数、穗粒质量)以及他们之间的相关性。结果表明,小黑麦品种OH2276株高最高,为136.77cm,但其种子产量低;安新麦83-25的综合性状最优,穗粒数最多,为109.19;北联4号,89D-8和DH796综合性状也较好,具有良好的应用前景;HB200上的综合性状最差,HB200下和OB74的综合性状较差。Abstract：In this paper,32 triticale varieties were chosen as the experimental materials to study the y components （spike length,spikelet number,grain number,grain weight） and their relationships. Results ind e c a- ted that the triticale variety,OH2276, had the highest plant height and was resistant to lodging, but its seed yield was low. Among 32 varieties, Anxin 83-25 had the best comprehensive characters, followed by Beilian No. 4,89D-8 and DH796; The integral traits of HB200 UP was poorest. ,HB200 Down and OB74 had poor performances.
