GREEN SEED COAT COLOUR RETENTION IN LENTIL - University ...

The tester set that was included in the study fell into two groups relative to
the distribution of the RILs (Figure 4.1 and Table 4.9). 1294M-23 was the most
desired green genotype from the tester set with an index score of 5.21 (Table 4.9).
All of the other members of the tester set except CDC Viceroy had index scores of
6.45 or higher. This makes the majority of the tester set similar to the less desirable
RILs. The least desired green line was CDC Sedley which had an index score of
7.64 when all sites and years were combined. CDC Viceroy had a mean index score
of 5.49. This shows that up until now there has been relatively little genetic
diversity for this trait in currently registered Canadian lentils. In the breeding
program much more genetic variation for better green seed coat appearance is now
available based on the fact that 1294M-23 has been used as a parent for the past five
years.
