In Vitro Propagation of Two Tomato Hybrids (Lycopersicon Esculentum Mill.) Via Tissue Culture Technique

In vitro flowering and fruiting in tomato (Lycopersicon esculentum Mill.)

In vitro flowering and fruiting were induced in plants regenerated from calli of leaf explants of Lycopersicon esculentum var. Pant 11. MS medium supplemented with 2 mg/l BAP displayed the best response followed by MS with 2 mg/l BAP, 1 mg/ l ABA and 0.5 mg/l IAA. Flower buds were developed both directly from callus and regenerated plantlets from leaf explants under 16 h (39.3 μmol m-2s-1) phot...

Tissue Culture Studies in Tomato (lycopersicon Esculentum) Var. Moneymaker

A protocol was developed for callus induction and regeneration in tomato (Lycopersicon esculentum) var. Moneymaker. Hypocotyl and leaf disc explants of tomato were used as a starting material for callus induction. Explants were cultured on MS medium having different concentrations of hormones. Maximum callogenesis from hypocotyls was obtained on MS medium supplemented with IAA (2 mg/l), NAA (2 ...

Effect of Genotype and Explant Type on in Vitro Shoot Regeneration of Tomato (lycopersicon Esculentum Mill.)

In order to select the best tomato cultivar for Agrobacterium mediated gene transformation studies, In vitro regeneration frequency of hypocotyls, leaf disc and shoot tip of five tomato cultivars (Lycopersicon esculentum) was investigated on a regeneration medium supplemented with 1 mg/l zeatin and 0.1 mg/l indole-3-acetic acid. Significant differences in regeneration capacity between genotypes...

The Inheritance of Self-Incompatibility in Hybrids of Lycopersicon Esculentum Mill. x L. Chilense Dun.

OTH self-fertile and self-incompatible species are found in the genus BLycopersicon (LAMM 1950). The self-incompatibility in L. peruuianum was shown to be of the Nicotiana or multiple-allelic gametophytic type by MCGUIRE and RICK (1954). Less extensive evidence suggested similar genetic control in L. hirsutum, L. glandulosum, and L. chilense (L. peruvianum f . dentatum) . I n addition, the inhe...
