What is The drought response of landraces of wheat from the northern Negev Desert in Israel about?

Diverse landraces of wheat, collected from the semi-arid (150 to 250 mm of total annual rainfall) Northern Negev desert in Israel were considered as a potential genetic resource of drought resistance for wheat breeding . These materials were therefore evaluated for their reponses to drought stress in agronomical and physiological terms . Up to 68 landraces, comprising of Triticum durum, T aestivum, and T compactum were tested in two field drought environments, in one favourable field environment, under post-anthesis chemical plant desiccation which revealed the capacity for grain filling from mobilized stem reserves, under a controlled drought stress in a rainout shelter and in the growth chamber under polyethylene glycol (PEG)induced water stress . Biomass, grain yield and its components, harvest index, plant phenology, canopy temperatures, kernel weight loss by chemical plant desiccation, growth reduction by PEG-induced drought stress and osmotic adjustment were evaluated in the various experiments . Landraces varied significantly for all parameters of drought response as measured in the different experiments, which was in accordance to their documented large morphological divers
