Abstract: | Most fenugreek, Trigonella foenum-graecum L. suitable for western Canada exhibit an indeterminate growth habit and take about 120 days to produce a good proportion
of high quality seed. Late maturity is a major inconvenience for seed producers in temperate climates prevalent in this region
where plants must mature within a much shorter growing season. The objective of this study was to develop early maturing fenugreek
mutants with a determinate growth habit to ensure uniform maturity within the 100 frost free days available on the Canadian
prairies. Seeds from Tristar Fenugreek, a forage cultivar developed for production in western Canada, were treated with 10–300 mM
ethyl methane sulfonate (EMS) for 2–24 h and plants were selected for determinate growth habit, early maturity and high seed
yield. This mutation breeding approach has detected new breeding material exhibiting early seed maturity coupled with high
seed yield, seed quality and determinate growth habit. Successful development of useful mutants in fenugreek was reported
before, but this is the first report on successful use of mutation breeding for improvement in quantitative traits in this
crop. |
