PAJ, New Iranian Triticale Suitable for Cultivation in Low- Input Lands of Moderate Region of Iran

Due to increasing of marginal and low yield lands in Khorasan Razavi and Jonoobi provinces like most parts of Iran that are not suitable for cultivation of wheat or barley, therefor triticale is more suitable for cultivation in such areas. These investigations were carried out for introducing new triticale cultivar during 8 years in Khorasan Razavi and Jonoobi and SPII. Promising line ET-84-17 derived from 34th ITYN (International Triticale Yield Nursery), PRTYT (Preliminary Regional Triticale Yield Trial) and ARTYT (Advanced Regional Triticale Yield Trial) in Mashhad, Karaj, Birjand and Moghan in 2002-03, 2003-04 and 2004-05, respectively. This line was selected based on grain yield superiority, better performance and morphological characteristics. Finally this advanced line evaluated in ERTYT (Elite Regional Triticale Yield Trial) in Mashhad and Birjand agricultural research stations during 2005-06 and 2006-07 years. Results showed that mean grain yield of this selected line (ET-84-17) was 7269 kg.ha-1 which was more than Juanillo 92 as check (6354 kg.ha-1) and had superiority in grain yield by about 14%, 4-6 day earlier heading and thousands grain weight about 2 g. Also superiority of ET-84-17 line in comparison with the checks in on-farm research was observed. Mean grain yield of ET-84-17 line, Juanillo 92 and Sanabad (checks) in Research-Extension trials were 6772, 5168 and 6005 kg.ha-1, with 31% and 12.8% superiority, respectively and ET-84-17 line was more suitable for cultivation in low yeilding lands (Khorasan Jonoobi).Therefore ET-84-17 triticale line with high yielding and better agronomic characteristics such as moderate early maturity was released as Paj cultivar. Total gross value benefits of substituting of this cultivar was 54482 Rials during 7 years.
