Ease of management

Builder has a vigorous growth habit which aids rapid establishment and resilience to pest attack.

It is medium tall, combining a higher biomass characteristic than the older hybrids which helps to build its high yields. It flowers early and benefits from medium-early maturity allowing the full development of its high oil content before a reasonably timed harvest.

It has shown consistent performance over several years of testing in official trials. 

Red = Low: 1–4 Orange = Medium: 5–6 Green =  High 7–9
