Abstract

Grafting experiment between the three commercial varieties of tomato (UPCA Selection #2029, Marglobe and Ace) susceptible to bacterial wilt and four different resistant rootstocks (UPCA Selection #1169, Hawaii #2, eggplant and pepper) was done in the vegetable Crops Section, Division of Horticulture, Department of Agronomy primarily to determine their graft affinities and the effects of grafting on the horticultural characteristics of these solanaceous vegetables.

All the susceptible tomato section exhibited a high degree of graft affinity when grafted on eggplant (UPCA Selection #64-43-36) and UPCA Selection #1169 Hawaii #2 tomatoes. In all cases, pepper (DP1) stock showed a very poor graft affinity to any of the susceptible scions. With good union between the graft components, the three susceptible scions expressed their horticultural characteristics as if grown on their own root system. UPCA Selection #2029 significantly had the most leaves and flower clusters, the tallest plants. The earliest flowering and the only scion that set fruits.

The observation suggests that the production of more flower clusters and fruits in rainy season UPCA selection #2029 is not due to the rootsystem but due to the vegetative parts.
