Abstract:
【Objective】 To screen out the processed tomato varieties with excellent quality in Xinjiang.
【Methods】 In this study, 17 processed tomato varieties were taken the experimental materials and their changes of growth period, soluble solids, fruit hardness, fruit hanging time, decay rate and pressure tolerance of 17 early, middle and late ripening varieties were studied.
【Results】 The results showed that the varieties with different maturation stages were more concentrated, with a difference of 7-15 days. The time of hanging branches was inversely proportional to the rate of decay. The lower the rate of decay, the longer the time of hanging branches. The order of the length of hanging branches was: precocious variety > medium-maturing variety > late-maturing variety; The order of soluble solids content of fruit during the whole period of red ripening was: late-maturing variety > medium-maturing variety > precocious variety;The fruit hardness of all varieties decreased gradually. The hardness of Shifan 28 of precocious varieties was the best, the best of medium-maturing varieties was Henshi 3402 andYaxin, and the best of late-maturing varieties were Henshi 9780 and Kenfan 2.
【Conclusion】 Three high-quality precocious varieties, Heinz 2206, Shifan 15 and Shifan 28 were selected by comprehensive comparison;Two medium-maturing varieties that were selected were: Yaxin 8 and SF227;Three late-maturing varieties that were selected were: Henshi 9780, Kenfan 2 and Kenfan 5.
