%X Four new F1 hybrids which incorporate the ripening inhibitor (rin) tomato mutation were compared with standard commercial tomato cultivars, including Flora-Dade, for the fresh market in New South Wales and Victoria. The rin gene, in the heterozygous condition, delayed the start of ripening by a few days, increased the interval between breaker and full ripe from 5 to 7 days compared with commercial cultivars, and increased the storage life of ripe fruits from 28 to 40 days at 20¦C. There were no significant differences between the level of red colour developed by the rin hybrids and reference tomatoes; however, the rin hybrid fruits took 4 days longer to reach full red colour. The fruits of rin hybrid were as firm as the reference tomatoes when picked at breaker and stored at 20¦C for 6 days. However, rin hybrid fruits were significantly (P<0.05) firmer than those of reference tomatoes when harvested at a full ripe stage. Of the 4 rin hybrids tested, HRAS 87-70, which showed the most promise, was released in February 1990 as 'Red Centre'.
