رخشان، رقم جدید گندم نان آبی با پتانسیل عملکرد بالا، مقاوم به زنگ های گندم، با کیفیت نانوایی خوب و مناسب برای کشت در مزارع آبی مناطق معتدل ایران

A breeding hexaploid wheat line named later Rakhshan was introduced to Iran through the CIMMYT ۴۱th-IBWSN international nursery with pedigree of " SHARP/۳/PRL/SARA//TSI/VEE#۵/۵/VEE/LIRA//BOW/۳/BCN/۴/KAUZ " in ۲۰۰۸. This line showed average grain yield of ۹۰۱۹ kg/ha compared to check cultivars Pishtaz, Shiraz, Marvdasht and Bahar average with ۹۰۶۰ kg/ha in Karaj, Kermanshah and Zarghan during ۲۰۰۸-۰۹ crop season. This genotype showed grain yield of ۸۷۱۰ kg/ha compared to ۷۹۱۰ kg/ha of four check cultivars: Parsi, Sivand, Bahar and Pishtaz in Karaj, Zarghan, Neishabour, Isfahan and Islam Abad-Gharb during ۲۰۰۹-۱۰. This line was tested in advanced and replicated trials over same ۵ locations at ۲۰۱۰-۲۰۱۱ with recorded grain yield of more than ۷ t/ha and measured good bread making quality. The adaptation and stability of this line was evaluated in a ۲ years' experiment tested over ۸ stations during ۲۰۱۱-۱۳ period which recorded grain yield of ۷.۶۹۵ t/ha against ۷.۵۸۲ of Parsi and ۷.۵۴۷ t/ha of Sivand. During testing of this variety under on-farm and demonstrational trials in farmer fields during ۲۰۱۳-۱۵ over several locations of temperate zone under normal irrigation conditions, average grain yield of ۸.۲۳۳ t/ha against ۷.۷۳۴ t/ha of Parsi cultivar was recorded. It showed also potential of ۱۰.۱۱۶ and ۱۱.۲۹۰ t/ha grain yields in Kermanshah and Alborz provinces respectively. According to the final investigations, reaction of Rakhshan to yellow rust and leaf rust was recorded as ۰ to ۳۰MS in the inoculated nurseries. In case of stem rust race Ug۹۹ reaction was ۴۰MR in Kenya. Bread making quality of this variety is good and it is relatively an early maturity variety.
