Validation No.: Shanghai Agricultural Products Inspection Rape (2006) 001
Breeding Unit: Shanghai Academy of Agricultural Sciences
Variety sources: Hybrids [(78A×LB03)CA×HF03] prepared from homozygous two-type line 78AB, lineage line LB03, and restore line HF03 were selected in 1999.
Characteristics: The whole growth period is about 237 days. Seedling growth potential, compact plant type, plant height 154 cm, effective branch 41 cm, 9 branches once, secondary branches 5, the number of effective fruit pods per plant is about 391, each grain number 17 tablets, a thousand grain weight 3.4 g; erucic acid content 0.67%, glucosinolates 18.59 μmol/g, oil content 40.5%. Sclerotinia-resistant disease is weak; the incidence of viral disease is lighter than that of “Hangyou 50†and heavier than “Huyou 15â€. Loose resistance is good, cold resistance is general.
Production performance: In the urban and rural areas in 2002 and 2003, the average yield per year was 118.2 kg, an increase of 27.2% over the control “Reserve Oil 50â€, reaching a very significant level and an increase of 3.0% over the control “Huyou 15â€; The performance of the production test in 2004 was poor. In 2005, the production test yielded an average of 151.6 kilograms per mu, an increase of 17.6% over the control “Huiyou 50†and an increase of 6.2% over the control “Huyou 15â€.
Cultivation points: 1, timely sowing, cultivating the strong quail: sowing at the end of September, three true leaf spray 150ppm paclobutrazol to prevent excessive growth. 2, pay attention to impurities: in the seedlings to remove the strains. 2, timely transplanting, appropriate thinning: suitable for the age of about 40 days, should not be too long, in November, mid-to-middle-day clearing transplanting density of 8000 per acre is appropriate. 3, scientific fertilization: wax fertilizer to be early and heavier, convulsions should not be more than fertilization, especially nitrogen fertilizer. 4. Disease prevention and pest management: The prevention and control of aphids, green worms, and diamondback moths are performed during the seedling stage. Do a good job of prevention and treatment of sclerotinia at flowering stage, spray and prevent disease 1 or 2 times.
Suitable areas for planting: Shanghai and surrounding areas.
