Abstract EN
Nine important agronomic traits were used to assess the genetic diversity of Tunisian tall fescue and to investigate the extent of genotype X environment (GE) interaction and its implications for breeding programs.
These traits were studied for three consecutive years in thirty-five spontaneous populations and three cultivars.
Panicle size contributed to seeds production, while the plant height at harvest and dry matter yield were selected for forage performance.
Analysis of variance demonstrated that population attitude depended on the year and environmental conditions.
Principal component analysis revealed significant similarities among some spontaneous populations and cultivars.
The relationship between environmental conditions and agronomic traits revealed the influence of altitude, soil texture and minimum temperature on forage production, seed yield, and the architecture of plants, respectively.
In addition, the local adapted ecotypes originating from Bizerte, Sidi Nsir, and Rass Rajel attained greater agronomic potentialities than control cultivars and were of considerable economic interest for the improvement of Tunisian tall fescue.
