The results showed that the variety of Tunhe No.8 followed by Shifan No.27 was most suitable for tomato concentrate and juice processing due to the superior processing characteristics like high conversion permu yield, TSS, and lycopene content. Liger 87-5 was the most suitable variety according to the requirement stipulated in the Chinese national standard QB/T 1394-91 for whole canned tomato while Tunhe No.8 was the best among the 6 varieties for canned pieces tomato due to easy peeling.
