ZiboCastor No.7

   
 ZiboCastor No.7 is a middle-maturing hybrid variety bred by Zibo Academy of Agricultural Sciences. It passed the national appraisal in Dec. 2005. It was certified by the Crop Variety Approval Committee of Shandong province in March 2010.

1. Yield: It was tested in the castor variety regional trial of Shandong province in 2008, the result indicated that its average yield was 4951.5kg/ha, which was 49.9% higher than that of Zibocastor No.2(CK). It was tested in the production test in 2009, the average yield was5020.5kg/ha, which was 59.1% higher than that of Zibocastor No.2(CK). The potential yield of one plant is more than 1000g.

2. Characteristics: For ZiboCastor No.7, it takes 120 days from seedlings emergence to the main fruit ears becoming ripe. It has the habit of indeterminate growth. The plant is 225cm high which has 4-5 first branches. The fruit ears look like pagodas and the main fruit ear is 65-95cm long. There are lots of thorns on the capsules. The seed is elliptical with some brown-red stripes on its coat.  The weight of 100 seeds is about 52g. Kernal rate (kernals /seeds ×100%) is 74.7%. The seed oil content is 50.08% and kernal oil content is 67.04%.
3. Key points of cultivation: It can be planted in wide regions. In China, it is suitable to be planted in such areas where the frost-free period is above 135 days. Sowing time: In middle regions of Shandong province, the spring sowing time is between the last ten-day period of March and the first ten-day period of April. To interplant in wheat fields, the sowing time is the first ten-day period of May. In such regions where the frost-free period is less than 135 days, growing seedlings and transplanting is available in castor cultivation. Cultivation density: In middle regions of Shandong province, the row spacing is 100-120cm, the spacing in the rows is 70-80cm, plants population is 10500-13500/ha. In such areas where the temperature difference is large and the sunshine is strong, such as Xinjiang Autonomous Region etc., the population of plants can be increased to 16500-18000/ha.
