                                            F1 Hybrid Indeterminate Salad Tomato


OUTSTANDING QUALITIES
     STRONG ROOT SYSTEM
     VERY HEALTHY PRODUCTIVE PLANTS
     OUTSTANDING QUALITY AND FLAVOUR

Malory is an early maturing, indeterminate hybrid for
production under protection. The plants are vigorous with
good fruit set ability and an outstanding yield potential.
Fruit are uniform, of excellent quality and deep oblate in
shape. Fruit colour is uniform (no green shoulders) with
very good firmness and excellent shelf life. Malory has high
resistance to Verticillium wilt race 1 (Vd1), Fusarium wilt
race 1 and 2 (Fol1.2), Tomato mosaic virus (ToMV) and
Fusarium crown rot (For).

SPECIAL VARIETAL REQUIREMENTS
 It is advisable to protect against Bacterial wilt, bacterial
    canker and nematode when grown in soil
 Suggested for production under protection
 Do not over fertilise during the first 4 - 8 weeks after
    transplant
 Malory requires N at moderate levels and K and relatively
    high levels

Resistance: is the ability of a plant variety to restrict the growth and development of a specified pest or pathogen and/or the damage they cause when compared to susceptible
plant varieties under similar environmental conditions and pest or pathogen pressure. Resistant varieties may exhibit some disease symptoms or damage under heavy pest or
pathogen pressure. Resistant varieties may also exhibit disease symptoms under sustained stress inducing environmental conditions such as soil temperatures above 27 °C.
