1999年春季在福建省惠安、福清两花生主产区 ,对国外引进的 5个抗黄曲霉花生品种进行生产力及收获前籽粒田间 A.f lavus自然感染研究。结果表明 ,5个抗病品种的田间抗性表现与室内鉴定结果相一致 ,均表现为抗黄曲霉侵入。但产量均比我省当家品种泉花 1 0号显著减产 ,减产幅度为 2 9.8%～4 2 .7%。其中 ICGV91 2 87稳定性比对照种好 ,ICGV94 449A、 J1 1稳定性与对照种差异不显著 ,ICGV 94 449B、 ICGV94 3 77稳定性比对照种差。这 5个抗病品种不适宜在我省生产上直接利用 ,适宜作为杂交亲本使用
In the spring of 1999 in Huian, Fujian Province and Fuqing two peanut main producing areas, the introduction of five foreign varieties of Aspergillus flavus to produce productivity and A.f. lavus before harvest grain field natural infection studies. The results showed that the field resistance performance of five resistant cultivars was consistent with the indoor identification results, both showed resistance to A. flavus invasion. However, the yield was significantly lower than that of the provincial variety Quanhua 10, with a reduction of 2 9.8% -4.27%. The stability of ICGV91 2 87 was better than that of the control. The stability of ICGV94 449A and J1 1 was not significantly different from that of the control. The stability of ICGV 94 449B and ICGV94 3 77 was worse than that of the control. These five resistant varieties are not suitable for direct utilization in the production of our province and are suitable for use as hybrid parents
