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 .
