摘要
对11个番茄育种品系选取与单株产量有关的5个性状与单株产量的关系进行逐步回归分析,结果表明:两种果型番茄的单株产量构成因素不同,小果型番茄(var.cerasiforme)的单株产量与单果重、花序数和每花序果数关系密切,每花序果数是最重要的产量因素;大果型番茄(var.vulgare)的单株产量与每花序果数和单果重关系密切,单果重是最重要的产量因素。
The stepwise regression analysis was applied to study the relationship between the related 5 traits and the yield per plant, among 11 tomato breeding lines. The results showed that the law of yield per plant was different between the lines of vat. cerasiforme and vat. vulgate. The yield per plant of vat. cerasiforme had a close correlation with the average weight per fruit, the average number of inforescences per plant and the average number of fruits per inflorescence of these 3 traits, the average number of fruits per inflorescence is the most important factor of the yield per plant. The yield per plant of var. vulgare had a close correlation with the average number of fruits per inflorescence and the average weight per fruit of these 2 traits, the average weight per fruit was the most important/actor of the yield per plant.
