All the latest news on Starke Ayres’ vegetable seed varieties, and the success that commercial vegetable seed farmers have achieved using them.

This page will also be updated with new seed variety releases and other commercial seed industry news.


Clearly visible is the growth of INVINCIBLE white pumpkin production in the Western Cape. INVINCIBLE is very tolerant of sunburn, has great internal quality and stores exceptionally well. White pumpkin production in South Africa has been given an INVINCIBLE boost by the introduction of a new variety featuring the concept of “Easy to Cut, Easy to Peel” with great taste. This unique variety is called INVINCIBLE and combines the quality characteristics of a grey pumpkin BUT with a white skin colour.

The advantage of the white skin colour is the improved tolerance to sunburn and this reduces grower risk significantly. Particularly important in areas where pumpkins are grown with vines, this tolerance allows a crop to remain on the land while grapes are harvested. INVINCIBLE also stores exceptionally well because discoloration of the white skin colour is much slower than with many grey pumpkins.

INVINCIBLE has a semi-bush growth habit with deep-flat shaped fruits and a thin, smooth skin. The flesh is much thicker and seed cavity smaller than most grey pumpkins. These features give INVINCIBLE an excellent size to weight ratio. This is one of the key aspects that attracted Preiss Visser of the farm Vorentoe to INVINCIBLE. Preiss has limited land available for pumpkin production and INVINCIBLE delivered for him a second year in a row. Preiss harvested 170 bins per hectare with an average weight of 5kg per fruit. Average fruit diameter was 28cm. Congratulations again Preiss with this excellent achievement.
