Some seed companies are now using harvestability as a measure of overall variety performance. The Canola Production Centre also measures the harvestability of certain varieties. As a producer, the best way to judge harvestability is to attend plot tours, dig out and look at individual plants from different varieties. This gives you a firm idea of the plant type you can expect to swath and combine in next year's crop. Green seed also affects producer returns.
Green seed relates back to the uniformity of the canola crop as it approaches maturity and harvest.
The more uniform the crop, the easier it is to decide when to swath. Earlier maturing varieties can also reduce the incidence of green seed. Most available seed performance data should provide both yield and green seed information. Disease resistance should also be considered in variety selection. There are now more varieties available with varying levels of Blackleg tolerance.
