Field trial
A total of eleven lines (Table 1) were subjected to a field trial within the growing season under well-irrigated conditions. The trial was held at the ARO located at Bet Dagan, Israel. Seeds that were propagated in the greenhouse were sown at March 7th, 2019, where each experimental unit was comprised of a 0.9m x 2m plot (Fig. S3). Raised beds were implemented and irrigation and fertilizer were applied using a dripping system. Most lines had between 3-5 replicate plots , except for the brown lines 53-1-B, 53-2-B and 53-3-B because their seed yield was insufficient for more than a single replication. Seeds for each plot were sown in a row alongside the dripping system in six rows. Seeds for each row were placed within a tube which was used to evenly distribute the seeds between rows. These seeds were weighed in advanced and were sown at a rate of 2.4 gr per 1.8m2 plot as a base line. Since AGW was different between lines, this proportion was used to standardize seeding rates (relative to the white cultivar) for each line. Express® herbicide was applied (0.1% with BB-5) 13 days after sowing (DAS), when the plants emerged .
