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).
