筛选品质优良的新疆主栽加工番茄品种

【目的】 筛选出品质优良的新疆加工番茄品种。【方法】 以新疆主栽的17个加工番茄品种为材料,研究17个早、中、晚熟品种的生育期变化、可溶性固形物、果实硬度、果实挂枝时间、果实生长期间腐烂率、果实耐压力。【结果】 不同成熟期的品种成熟比较集中,早、中、晚成熟期相差7~15 d;挂枝时间与腐烂率成反比,腐烂率越低的品种挂枝时间越长,挂枝长短的顺序为早熟品种>中熟品种>晚熟品种;整个红熟期间果实的可溶性固形物含量顺序依次为晚熟品种>中熟品种>早熟品种;所有品种果实硬度都呈逐渐下降的趋势,早熟品种石番28硬度保持最好,中熟品种中亨氏3402、亚心8号最好,晚熟品种中亨氏9780、垦番2号硬度保持最好;早、中、晚熟品种中最耐压的分别是垦番3、SF227、石番35。【结论】 选出优质早熟品种3个,亨氏2206、石番15和石番28;中熟品种2个,亚心8号、SF227;晚熟品种3个,亨氏9780、垦番2号和垦番5号。

Selection of Main-Planted Tomato Varieties in Xinjiang

【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.
