Development of oil seed crops is the most important aim in our country to achieve self sufficiency. This study was conducted to assess the suitability of oil brassicas species in rain-fed warm areas of Iran. This research was performed for three years in Agricultural Research stations of Gonbad (Golestan). Twenty varieties and hybrids (B. napus, B. rapa, B. juncea ) were compared in RCBD with three replications under rain fed conditions. Each plot had 4 rows 5-meter long. Combined analysis results indicated that there were significant differences at 1% probability level among years and varieties for No. of days to maturity, No. of pod per plant, oil%, oil and seed yield. The highest seed yield was obtained in the 2nd year (2103.48 kg.ha), followed by the 1th and 3rd year (1771.50 and 1575.13 kg.ha, respectively). Namely, year environment factor had a significant effect on the rape seed product. j-98-102.51-5 (B. juncea), Alexandra and comet (Spring B. napus) showed the highest seed yield (2484, 2326 and 2290 Kg.ha, respectively). Regression analysis via step by step method explained that No. of pod per plant and oil percentage had significant positive effects (508.53 and 96.48 respectively) and No. of days to maturity significant negative effect (-78.63) on the seed yield. Factor analysis extracted four factors. Factor loading of the first three eigen values showed that the first three factors explained 98.794%, sum of variance. Rates of first, second and third factors were 45.575%, 36.816% and 16.403%, respectively. The first factor, second factor and third factor were named productivity factor (seed yield and oil yield), sink factor (No. of pod per plant), fixed capital factor (No. of day to maturity and plant height) respectively. Generally, j-98-102.51-5, Alexandra and comet varieties are advisable for Fall planting under rain fed conditions in Gonbad area because they had the highest seed yield and earliness. Also, we can introduce less No. of days to maturity (earliness) and more No. of pod per plant as select index under rain fed conditions in Gonbad.
