Abstract:

Drought is the major environmental factor limiting wheat production worldwide.

Developing novel cultivars with greater drought tolerance is the most viable solution to ensure

sustainable agricultural production and alleviating threats to food-security. Here we established a

core-collection of landraces and modern durum wheat cultivars (WheatME, n = 36), from the Middle

East region (Jordan, Palestine and Israel) aiming at unlocking the genetic and morpho-physiological

adaptation to semi-arid environment conditions. Interestingly, genetic analysis of the WheatME

core-collection could not distinguish the landraces according to their country of origin. Field-based

evaluation of the core-collection conducted across range of contrasting environmental conditions:

Til-Palestine, Bet-Dagan-Israel and Irbid-Jordan with annual precipitation of 500 mm, 360 mm and

315 mm, respectively. The Til environment showed highest grain yield while the Irbid environment

showed the lowest values. Analysis of variance showed a significant Genotype Environment

interaction for plant phenology traits (plant height and heading date) and productivity traits

(1000-kernel weight, and grain yield). Principal component analysis showed three main cultivar

groups: High yielding lines (modern durum cultivars, and landraces), tall late flowering landraces,

and landraces with high grain weight. This knowledge could serve as basis for future breeding efforts

to develop new elite cultivars adapted to the Mediterranean Basin’s semi-arid conditions.
