THE BREEDING OF TOMATOES FOR PEELING
Because in several areas at the maximum fruit colour corrispond a pH value and a ratio sugar/acidity too high, some possibilities are indicated to improve the fruit colour through genes modifying the fruit colour directly or indirectly by a better leaf/fruit ratio.
The quality parametere are greatly influenced by environments, so that different scoring systems must be used in the breeding programmes in the different areas.
The influence of the maturational effects on the main characters of the peeling tomatoes are shown; also at the harvesting time in varieties with a concentrated fruit-set there is still an intra-plant variability among apparentely similar fruits. The consequences of such influences on the breeding programmes are indicated, as regards an adequate sampling and the selection procedure in the early generations.
