Abstract EN
Climate change models predict frequent and intense droughts in the world.
Development of drought-tolerant species and cultivars is necessary to cope with such changes.
Forage grass species are affected, especially in the Mediterranean region.
The aim of the present study was to investigate the diversity for drought survival, summer dormancy, and productivity within a cocksfoot population.
The study was conducted in Morocco, under field conditions from 2011 to 2013.
283 genotypes of cocksfoot and parents were tested, characterized for dry matter yield, heading date, plant height, senescence, summer dormancy, and drought survival.
Results exhibited a large variability between traits.
79% of the population had survived after severe drought summer while 57% yielded more than both parents.
Also, 63% of the progeny had an intermediate score of summer dormancy estimated by senescence score.
Large variability was also noticed for heading date and plant height.
Several accessions combined a high yield and persistence under severe summer drought.
Which explain the significant correlation (r = 0.18, P < 0.005) founded between total dry matter accumulated in 2013 and plant survival.
Accordingly, our results showed that we can rise persistent and resilient genotypes among population with a good level of biomass
