本研究由美國引進13加工番茄機收品種及本省現行栽培品種二種計15品種進行品種一次採收產量及品質之評估,15品種中公頃產量達63噸以上者有UC-82B,UC-82,VF-6203-1,VF-9209及Poto-98等五品種,其中品種UC-82及Poto-98一次採收率分別為92.7%及96.7%,產量高,植株矮化緊密,著果集中性良好且極早生,品質符合加工要求,很適合一次機械採收;UC-82B,VF-6203-1及VF-9209等三品種一次採收率雖高達87.7%,98.5%及97.5%,但因著果集中性及早熟性表現不如UC-82及Poto-98,利用為一次採收品種尚有待進一步觀察評估。其他引進品種如Heinz-2653等一次採收率雖高,果實硬度亦佳,但產量不高,且植株開張性大,較不適合本省採用;本省加工番茄品種TK-70及TNS-2一次採收率分別為40.6%及61.7%,一次採收公頃產量僅為28.4噸及41.5噸,均不適合做為一次採收用品種。

Studies on the Techniques for Once-over Harvesting of Processing Tomato

1. Screening of processing Tomato Cultivars

S. L. Hwang

Summary

Experiments were conducted in the field to evaluate quality of the 13 processing tomato cultivars newly introduced from the U.S.A. and the 2 local cultivars for once-over harvesting purposes. Five cultivars i.e. UC-82B, UC-82, VF-6203-1, VF-9209, and Peto-98 outyielded 63 m.t./ha of fresh fruits. Due to their high yielding potential, high once-over harvesting percentage (92.7% and 96.7%, respectively), bush type plant, early maturity and concentrated fruit setting, cultivars UC-82 and Peto-82 and Peto-98 were suitable for once-over harvesting. Cultivars UC-82B, VF-6203-1 and VF-9209 also were with had high once-over harvesting percentage (87.7%, 98.5% and 97.5%, respectively), but they were not as good as UC-82 and Peto-98 in early maturing, concentrated fruit setting and other horticultural characteristics. Advanced observations and evaluations of the promising lines are needed in the future. Rest of the introduced cultivars such as Heinz-2653 was with good firm fruit and high percentage of once-over harvesting, but they produced fewer yields with open plant type. Therefore, they were not suitable for once-over harvesting in Taiwan. The once-over harvesting percentages and yield of the 2 local cultivars TK-70 and TNS-2 were only 40.6%, and 28.4 m.t./ha, 61.7%, and 41.5 m.t./ha, respectively. They were also not suitable for once-over harvesting.
