الملخص الإنجليزي

This study was carried out in the semi- arid region of Al-Wasiah near to Rabba area, Al- Karak Governorate, Jordan to determine the effects of different water treatments on yield, yield components and some drought related traits in wheat.

Eight genotypes were tested under three treatments; rainfed condition (control= 262.8mm), partially supplementary irrigation (PSI= 220mm irrigation at anthesis stage+ 262.8mm rains) and continuous supplementary irrigation (CSI= 377.5mm continuous irrigation at 2-3 weeks intervals+ 262.8mm rains).

Seven durum wheat genotypes (Sham1, Omqais, Acsad65, Bani Suef6, Bani Suef4, Horani Nawawi, Dairalla6) and one bread wheat genotype (Ammon) were included in this study.

Yield, yield components and spike related traits, morphological, phenological traits and chlorophyll content were significantly increased by irrigation.

PSI treatment significantly increased grain yield by (50.2%), while CSI doubled grain yield (121%) when compared with the control treatment.

Considerable variations among genotypes were observed under different irrigation treatments.

The top yielding genotypes under CSI were Acsad65 (4716.7 kg ha-1), Dairalla6 (4586.7 kg ha-1), Bani Suef6 (4460 kg ha-1) and Omqais (4360 kg ha-1).

Under PSI, Sham1 (3303 kg ha-1) followed by Dairalla6 (3193.3 kg ha-1), Horani Nawawi (3130 kg ha-1) and Bani Suef6 (3026.7 kg ha-1) displayed maximum grain yield and longest grain filling period (35 days).

Under control treatment, Sham1 (2266.7 kg ha-1), Omqais (2253.3 kg ha-1) and Acsad65 (1963.3 kg ha-1) showed higher grain yield and they displayed low drought susceptibility index, implying their high genetic potential for drought tolerance.

In conclusion, irrigation improves yield components (number of kernels per spike, number of tillers and grain size), and thereby lead to substantial increase in grain yield.
