| description | Tobacco (Nicotianat abacum L.) is a worldwide economic crop, and tobacco industry is an important resource of tax revenue in China. Style, quality and economic characteristics of tobacco are the focuses of attention for both tobacco breeders and companies.Most tobacco economic characteristics are quantitative traits, affected by variety, environment, variety-bylocation interaction and other unknown ecological factors. It is very crucial to understand the contribution rates of these factors to the economic characteristics of tobacco, so as to screen appropriate varieties for specific tobacco producing regions.A regional variety trial with random complete block design was conducted in multiple locations in 2014. Totally,14 Fen-flavor tobacco varieties and 11 testing locations in 4 Fen-flavor tobacco producing regions were arranged with 3 blocks in each location. Six main economic traits, the average price, the grade index, the superior tobacco rate, the grain per 667 m<sup>2</sup>, the output value per 667 m<sup>2</sup>, and the yield, were investigated. Analysis of variance and stability were performed based on a mixed linear model including variety effects, location effects, variety-by-location interaction effects, and block effects. QTModel and SAS software were employed for the analysis.Variance analysis results showed that variety effects, location effects and variety-by-location interaction effects were significant for all the six economic traits. Wherein, location effects had the highest contribution, accounting for 60%-90% of total variation of each economic trait, and nearly 90% variance of the average price came from location effects. In addition, variety related effects explained 8.9%-42.7% of the total variance for each economic trait. In terms of the contribution rate of location effect, the order of traits from high to low contribution was the average price, the grade index, the superior tobacco rate, the output value per 667 m<sup>2</sup>, the yield, and the grain per 667 m<sup>2</sup>. The block effects were only significant for the average price, the grain per 667 m<sup>2</sup>, and the grade index, and it only contributed at most 4% to the total variation.In adaptability evaluation, according to the results of multiple comparisons for comprehensive and each economic trait, the varieties marked by “a” were selected as appropriate ones for the region, and within them those with trait mean equal to or larger than that of all appropriate ones were selected as the most appropriate varieties. If more significant differences between varieties were detected, the varieties whose trait mean was larger than the total average would be regarded as the appropriate ones. As a result, the most appropriate varieties were PVH1452, Yunyan208, Yunyan105 for the region of Yunnan Plateau Basin; Yunyan116, Yunyan119 for the region of Yunnan Low Latitude Valley; Yunyan208, Yunyan105, Yunyan110, Yunyan119 for the region of Wumeng Mountain; Yunyan208, Yunyan97 for the region of West Fujian Wuyishan.Results on variety stability showed that location effects were the main sources of total variation, and as high as 70%-99% of the total variation could be explained by location effects. It suggested that Fen-flavor tobacco’s economic characteristics are not stable across different planting areas. |
