Off season phenotyping and line segregation
The subjected Teff lines were propagated in 10L pots in the greenhouse
off-season. Each line originated from a single panicle of a single
plant. The initial collected seed set AGW (0.23-0.60 mg) as well as AGW
scored from the greenhouse (0.22-0.50 mg) are presented in Table 1. MPH
ranged from 147 to 200 cm. The white cultivar and the pure brown
cultivar 44A-163-B presented similar heights. The white cultivar had
more stems per pot and panicle emergence was about a week earlier than
the rest of the lines under these condition.
Three lines that had mixed color seeds were separated as detailed in
Table 1. The proportion between the brown to white seeds was tripled
from 0.021 to 0.064 within a generation of prorogation. Whereas in 53-2
and 53-3 no dark brown seed were detected upon collection. However,
after second round of propagation in the field dark brown seed were
found in those lines (0.105 and 0.015 for 53-2 and 53-3 respectively).
