摘  要:
通过对121个小麦杂交组合中14个增产幅度较大的超标优势组合F1代的产量性状、株高和抗病性等进行分析,发现各超标优势组合的产量三因素均具有较高水平。在产量三因素中,有效穗数的优势对产量优势的贡献最大,其次是每穗粒数,千粒重优势对产量优势的贡献最小。此外还发现,湖北麦区生态条件下,杂种F1代株高为88~97 cm、父本比母本植株高15 cm较佳,亲本选配时,最好选择双亲或其中之一为抗病品种,以利于选育出抗病的F1代。

摘  要:
Yield characters,plant height and disease-resistance of 14 F1 hybrids with in 14 hybrids heterosis out of 121 hybrid crosses were analyzed.The results showed that all the three yield characters(spike kernels,kernels/head and 1 000-kernel-weights) was at high level.Among the three characters,spike kernels had the biggest contribution to grain yield;while 1 000-kernel-weight had the smallest.Analysis on height and disease-resistance of hybrids and parents indicated that the height of hybrids should better be 88~97 cm,and height of male parent should be 15 cm higher than that of female parent.It was good for getting disease-resistant F1 if one or both parents had disease-resistance.
