Abstract

The Amin wheat cultivar, with the pedigree "KAUZ/LUCO-M//PVN/STAR/3/ Yaco/2*Parus/4/Pishtaz", was developed through a national irrigated bread wheat breeding program for the temperate climate of Iran. Initial and advanced crosses were conducted at the Seed and Plant Improvement Institute in Karaj, Iran, while the evaluation and selection of segregating generations (F2-F6) carried out at the Zarghan Research Station in Fars Province. Selected lines, including M-94-14, advanced to both preliminary and advanced yield trials. Under optimal irrigation conditions in temperate climate adaptation trials, the M-94-14 line (Amin cultivar) achieved an average grain yield of 6950 kgha-1, representing a 3.9% and 5.7% yield advantage over the control cultivars Parsi and Baharan, which yielded 6688 and 6574 kgha-1, respectively. This line exhibited desirable baking quality traits, including favorable grain protein content, Zeleny sedimentation volume, bread loaf volume, grain hardness index, and SDS sedimentation height. Additionally, it demonstrated acceptable resistance to yellow and leaf rusts. On-farm trials across various regions showed that the Amin cultivar achieved a grain yield of 6820 kgha-1 under optimal irrigation conditions, outperforming the average grain yield of control cultivars, which was 6609 kgha-1. Given the superior performance of this line compared to existing cultivars in temperate climate of Iran, the M-94-14 line was officially released as the Amin cultivar in 2019.
