AbstractAiming to evaluate the CIMMYT durum wheat (Triticum turgidum var. durum) cultivars, yield trials for 49 entries (International nursery 29IDYT) IN comparison with the local Gerardo cultivar were conducted at al-Latifyia Experimental Station during 1997/1998-1999/ 2000. Alpha lattice design with tow replictions for the 1st season and a randomized complete block design with three replications for the 2nd and 3rd seasons were used. Pooled analysis for the three seasons was practiced.
Results revealed that days to heading, plant height, weight of 1000 kernel, and grain yield were affected significantly by the different cultivars under investigtion. No significant effect for the different sowing seasons yield only, whereas, the cultivars x sowing seasons interactions showed significant effects for almost all traits under investigation. In general, days to heading, plant height, and weight of 1000 kernel were ranged between 105-113.7 days, 84.4-101.0 cm., and 37.6-48.1 g, respectively. These results reflect the expanded variation in grain yield among cultivars. All entries out yielded 3446 to 5067 kg/ha. Twenty-one. 12, and 18 CIMMYT introduved durum wheat cultivars were exceeded in early heading, short plant height, and high grain weight over the local cultivar, respetively.
The CIMMYT entries 2 and 28 (Yavaros 79 CM9799-126M-1M-5Y-0M and MINIMUS/COMB DUCK 2//CHAM 3 D98225-A-3Y-04M=040YRC-6M-0Y), respectively of the mentioned nursery gave the highest grain yield. Which was over than 5 t/ha with an increase of 25% over the local cultivar.
