摘要：

为了探索不同栽培环境对番茄部分数量性状DUS测试结果的影响，选取对30个番茄DUS测试标准品种和2个测试品种及其选定的2个近似品种，进行塑料大棚和露地2种不同的栽培环境对番茄10个数量性状的DUS测试结果影响的研究。结果表明：2种栽培环境对除第一花序着生节位和心室数以外的8个数量性状均存在显著或极显著的影响，导致在部分数量性状代码判别和特异性的判定上存在着差异。通过标准品种数量性状分级标准的校正，可以有效消除因栽培环境不同而造成的影响。

Abstract:

The objective in this article is to explore the effect of different planting environments on the DUS testing results of some quantitative characteristics of tomato. We carried out research on the influence of two different planting environments of plastic greenhouse and field on the DUS testing results of 10 quantitative characteristics of 30 tomato standard varieties, 2 candidate varieties and 2 similar varieties. The results showed that the two planting environments had a significant or extremely significant influence on other 8 quantitative characteristics except number of 1st flower’s node and number of locules, resulting in some differences on estimating note of quantitative characteristic and assessing distinctness. Calibrating scale index of quantitative characteristics of tomato standard varieties can effectively eliminate the impact caused by different planting environments.
