| 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J09。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: | 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. |
