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.
