بررسی مقدماتی هیبریدهای کلزای جدید ایرانی در شرایط دیم نیمه گرمسیر

Present research was conducted to study on preliminary yield new rapeseed genotypes at semi warm rainfed conditions. This study was performed by 40 genotypes associated with Hyola401and Hyola308 as check at (2008-2009) in dry land Gachsaran agricultural research station. Each genotype was planted systematically in 5 rows in 4 meters length, 25 cm spacing from each other. During growth season, some agronomical and morpho- physiological traits were recorded such as stemming date, number of pod per plant, number of seed per pod, plant height, days to flowering and days to maturity and After harvesting, TKW and grain yield were measured. Finally due to design systematic, all of line only compare with check. Mean and range of days to maturity in genotypes was 160.5 and 156 - 167 days, respectively. Variation range was for number of pods per plant 15 (lines 31 and 38) - 95 (line 1), number of seeds per pod 17 - 25, and kernel thousand weight 2.1 (line 22) - 3.4 (line 7). The highest seed yield belonged to hybrid Hyola 401(503.8 Kg/ha). And to sever drought, yield of line were most low and for this reason any line not selected.
