Tozer Seeds

Alliums

Leek

Tozer started breeding leeks in the 1970's when we first identified the male sterile character that makes hybrid production possible, however it was not until the 1990's that the method to use this character was determined.

The development of hybrid leeks has been a complex operation, but the expertise of our breeding staff has brought an increasing range of top quality hybrids to the marketplace.

The parent lines of all our hybrids have been carefully chosen to give excellent uniformity, vigour and good disease resistance, particularly to rust. We are pleased to offer a selection of our newest F1 varieties which are available to growers for the first time.

Salad Onion

Tozer Seeds are continuing to develop new Allium cepa salad onion varieties. The incorporation of winter hardiness into a traditional White Lisbon type was an early success. More recently Ramrod, a winter hardy variety with erect stiffer leaves was released, followed by Eiffel, an erect, stiff leaved, slow to bulb variety for summer use.

Our aim is to further develop A. cepa salad onions and improve our interspecific variety Guardsman. We are also active in developing improved A. fistulosum varieties such as Summer Isle.


Sow A. cepa A. fistulosum	February - June for summer/autumn crop July - Sept for winter/overwinter crop April - June for summer crop
Suggested Density	2,400,000 - 2,600,000 per hectare
