Breeding and Cultivation of a New Rust-resistance Peanut Variety, Fuhua 6

In order to breed a new variety of peanuts with wide adaptability, high yield and high-quality for Fujian, Fuhua 6 was nurtured by the Institute of Crop Sciences, Fujian Academy of agricultural Sciences. It had a high yield with a high-oil content. The variety took part in the 2008-2009 provincial spring peanut regional tests, had a production experiment executed in the spring of 2010, and passed the field evaluation held by the peanut professional group of the non-major crop variety appraisal committee of Fujian province in August 2010. In 2008, its pod yield was 3 926.85 kghm-2, increasing 11.05% over the control, Quanhua 10. The kernel yield was 2 640.00 kghm-2, increasing 9.54% over the control. And, in 2009, the pod yield was 4 039.20 kghm-2, increasing 8.50% over the control, Quanhua 7. The kernel yield was 2 672.25 kghm-2, increasing 7.71% over the control. In the spring of 2010, the production experiment on Fuhua 6 was carried out. It passed the evaluation by the peanut professional group of Fujian Crop Variety Approval Committee in August, and was completed in December 2010. Fuhua 6 was examined and approved by the provincial government in February 2011. The kernels contained 54.04% crude fat, 24.48% protein. They were susceptible to bacterial wilt, had a medium resistance to leaf spot, but high resistances to rust, flood and lodging. The growth period of Fuhua 6 was about 129 days. The variety was suitable for sowing at the end of February to early April, and in late July to early August as well, from the southern to the northern regions in Fujian. The recommended planting density was 18 000-20 000 kghm-2in spring, and 20 000-22 000 kghm-2 in autumn. During its growth period 67.5-82.5 kghm-2 of N with the ratio of N∶ P∶K of 1.0∶0.8∶1.2 were needed. The base fertilizers included 50% of N fertilizer, 100% of P fertilizer and 70% of K fertilizer, and the remainder as top dressing.
