摘要

本文介绍了数量性状对大麦植株生产性能影响的研究结果。选取28个基因型春二行大麦品种各30株典型植株，测定其株高、有效分蘖量、穗长、主穗数、主穗重、千粒重和生产性能。结果表明，主穗籽粒的分蘖性能与有效分蘖能力、籽粒重量呈显著正相关。通径分析表明，主穗粒重对植株生产性能的直接影响最大(0.61)。结果表明，“穗长-主穗粒重-性能”和“穗粒数-主穗粒重-性能”是大麦植株性能选择的重要途径。

Correlation and path analyses of the performance elements in spring barley cultivars

The article presents the results of studying the influence of quantitative traits on the barley plant performance. Thirty typical plants were selected for each of the 28 genotypes spring two-row barley cultivars and their height, productive tillering capacity, spike length, number and weight of kernels from the main spike, 1000-kernel weight, and performance were measured. As a result, we found significant positive correlations between the performance and productive tillering capacity and weight of kernels from the main spike. Path analysis showed that the weight of kernels from the main spike had the greatest direct effect on the plant performance (0.61). We have established that the paths “spike length – weight of kernels from the main spike – performance” and “kernel number per spike – weight of kernels from the main spike – performance” are of the greatest importance in select for the barley plant performance.
