| چکیده | ||
| Line WB73-6 (Trompillo, CMB74A-432-25B-1Y-IB-1Y-OB) was first introduced in Iran through a nursery received from CIMMYT in 1989. It was selected in a preliminary experiment in Zabol research station among the genotypes of IBON in 1990. In other preliminary and advanced yield trails carried out in Zabol and other stations in southern provinces of Iran with warm climate in 1991-1997, line WB73-6 produced higher grain yield than other advanced lines and check cultivars and showed also good adaptability and yield stability. The global mean grain yield of this line in these experiments was 4902 kgha-1, which was 404 kgha-1 higher than that of the check cultivars. The most specifications of this line are geneal compatibility, high tolerance to loding and diseases, moderate tolerance to grain loss, tolerance to axis breaking, tolerance to drough and high temperature in late growth stages, high 1000 kw (42 g) and high seed protein contents (12%). In on-farm trials carried out in three locations in Zabol and two locations in Khuzestan province during 1999 and 2003 cropping seasons, its grain yield was 350-580 kgha-1 higher than the yield of check cultivars. This line was officially registered in Iran by the National Cultivar Release Committee of Agricultural, Education and Extension Organization with the name of Nimrooz in 2009. | ||
