Comparison the yield, yield component of canola varieties and relative resistance in south salinity soil of Khouzestan province

Resistance or adaptability of varieties for cultivation are used due to more efficiency in salinity soil. This trails was carried out in randomized complete block design with four replications، 12 canola varieties، in salinity soil with 11. 2 ds. m-1 and without salinity soil limitation in two years during 2004-2005 and 2005-2006 in Khouzestan agricultural research center. Two years compound analysis results were showed significant difference in yield and yield component in each location for all varieties. Salinity limitation were reduced germination 6. 5 percent، 2. 9 day flowering duration، 2. 5 day maturity، 45. 6 centimeter plant height، 23. 8 pod per plant، 2. 1 seed per pod، 0. 95 gram thousands seed weight، 1174. 9 and 433. 7 Kilogram seed and oil yield per hectare. All canola’s varieties were sensitive to salinity based on Fischer index except option500 and pp-401/15E. In spit of this results، the Hyola Hybrids were recommended four two both environmental conditions، according theories high yield potential and early maturity and in other hand RGS003 verity was recommended for salinity soil of south Khouzestan.
