Characterization of cocksfoot (Dactylis glomerata L.) population for growth traits and summer dormancy

Abstract

Cocksfoot is one of the four most important forages in the world, it is persistent and summer drought tolerant. Under Mediterranean climate, one way to produce without irrigation is to use plants resistant to drought, such as some perennial grasses as cocksfoot. The present work was conducted during 2011/2012 cropping season to evaluate some traits of progeny generated from a cross between a summer dormant genotype Kasbah cv and a summer active genotype from Medly cv under Mediterranean climate.The aim of this study was to gather hybrids pools according to common features with relation to summer dormancy. Measurements of dry matter yield, heading date, plant height, plant growth rate, senescence and summer dormancy were taken for the 229 F1 hybrids. Results showed a large variability between hybrids for all traits. 4% of hybrids were more dormant than the parent Kasbah, 35 % of hybrids yielded more than Medly, 73.8 % of progeny exceeded parents growth rate, 60 % had the greatest biovolume, more important than both parents. Significant correlations (P <0.0001) were found between all traits except heading date and senescence. Cluster analysis (CA) revealed eight groups and subgroups which showed 80 % of phenotypical similarities within hybrids and parents.

“…One more likely explanation is that only genetic characteristics differentiate these groups. Cluster analysis (CA) showed eight groupings and subgroups with 80% phenotypic similarity between hybrids and parents, according to the findings of Zhouri et al (2017), who categorized genotypes and parents graphically based on measured attributes.…”

“…During the season 2019, observations of morphological characteristics as follow were made: plant height (cm), leaf length (cm), leaf width (mm), length of peduncle(cm), node number (number), number of tillers per plant (number), panicle length (cm), number of spikelet per panicle (spikelet/panicle), 1000 seed weight (g) (Davis, 1985;Amirouche and Misset, 2007;Özköse and Tamkoc, 2014;L Zhouri et al, 2017;Zhouri et al, 2019).…”

“…Cocksfoot is one of the most important fodder crops in Europe and in the world [36,37]. It attains high yields and is disease-resistant [36], as well as highly resistant to drought [38]. Due to its high quality as fodder, it is used for production of hay and silage and for grazing [36].…”
