Compare genetic differences between tomato varieties that are open pollinated, such as traditional heirloom varieties, and hybrid tomato varieties.
HEIR LOOM VARIETIES | HYBRID VARIETIES |
Isolated from other varieties in same plant species | Cross within the heirloom varieties of same species |
More pure in genetic line, true to type | Hybrid of two desired traits can be seen, not true to type |
Less costly, high storage ability, uniformity and characteristics more pertinent to the processing | Superior disease-resistant genetic line |
The growth rate is stable between 5-7 weeks | The growth rate is phenomenal, double the rate of open-pollinated varieties |
Detectable variations can be seen, deviated too much from the characteristics desired originally | Scope for organic farming |
