Abstract

‘Ohio 8243’ is a main season tomato (Lycopersicon esculentum Mill.) adapted for machine harvest and bulk handling and exhibits processing quality especially suitable for the production of peeled, coreless whole-canned tomatoes (whole-pack), as well as for juice and sauce. Extensive test acreages have been grown by the mid-western and eastern U.S. and Canadian tomato processing industries. The new cultivar has been well received by growers and processors and its use is increasing.

Abstract

Efficiency of somaclone production was examined using 10 processing tomato cultivars and 18 growth regulator treatments. Although zeatin has been reported to induce shoot development most readily, a combination of IAA (5.7 µmol·liter–1) and kinetin (4.7 µmol·liter–1) was found to be equal to zeatin in shoot regeneration efficiency and reduced the time required for shoot production. Rooting was achieved by transplanting the in vitro-produced shoots to Pro-Mix under intermittent mist in a greenhouse. Chemical names used: (E)-2-methyl-4-(1H-purin-6-ylamino)-2-buten-1-ol (zeatin); 1H-indole-3-acetic acid (IAA); N-1-furanyImethyl)-1-H-purin-6-amine (kinetin).
