Abstract:
Line N-78-14 with the pedigree of SHA4/CHIL CM91099-25Y-OM-3N-1Y-OYZ-O10M-OY-3M-O10 was obtained from CIMMYT, Mexico in 1996 through High Rainfall Wheat Screening Nursery. Preliminary evaluation of the genotypes in International Nursery in Gorgan and Sari Research Stations during 1996-97 cropping season, resulted in selection of this line as one of the most high yielding genotypes. Selected lines were evaluated in preliminary regional wheat yield trials of north warm and humid climate in 1997-98 in four locations of Gorgan, Sari, Gonbad and Moghan. Line N-78-14 together with other selected lines were tested then in advanced regional wheat yiled trial (ARWYT-N) in 1998-79, and later in ellite regional wheat yield trials (ERWYT-N) for three years in four locations. In all these experiments line N-78-14 was the most high yielding line compared to the check cultivar and other lines. Evaluation of line N-78-14 for resistance to different diseases in special disease nurseries in different locations under artifical inoculations indicated that in most locations, this line was resistant or moderately resistant to yellow rust and leaf rust while tolerated well fusarium head blight and septoria leaf blotch diseases. Line N-78-14 has been evaluated as a good baking quality wheat containing high molecular weight glutenine allels 2*, 7+9 and 5+10. Due to high yield, yield stability and compatibility, resistance to diseases and good baking quality, this line was introduced as Darya in 2006 for cultivation in warm humid climate regions of Khazar, Iran.
