Abstract

THE existing work aimed at evaluation of 58 old and modern durum wheat grown under south Mediterranean conditions. The experiment was conducted in a randomized complete block design at two locations (ITGC-AES of Setif and Khroub, Algeria) considered during two successive winter seasons of 2015/16 and 2016/17. Results indicated that, averaged across seasons and locations, modern varieties outperformed older varieties in terms of grain yield, spike number, spike weight, number of kernels per square meter, harvest index, spike fertility and stay green. Old varieties surpassed the modern ones in terms of straw yield, lateness, tallness and flag leaf area. Whereas, modern varieties were stress tolerant and more responsive to improved growth conditions, showing agronomic stability type. Old varieties were characterized by a minimal responsiveness to improved environmental conditions, stress tolerance, and biological stability type. Pearson's correlation coefficients and path analyses indicate that, in both sources of germoplasm, the strong influence of biomass, spike number, spike fertility and harvest index on grain yield. Physiological traits had negligible direct effects and small indirect effects via biomass, spike number and harvest index. Lastly, principal component analysis revealed that old varieties represent an important gene pool for important traits among which plant height and straw yield. Furthermore, the differences between both sources of germoplasm can be usefully used in breeding program (Gene-bank) to enhance yield potential, stability and resilience to changing climate of the future varieties.
