Abstract: The new variety, Fuhua 3 nurtured by sexual hybridization and mixed pedigree selection method, Wuyou 7 as female parent and the middle of the breeding material 9817-36-2 breeded by us as male parent in spring 2002, has the high-yielding, drought-tolerant and adaptive extensive characters. The variety takes part in the province in 2007-2008 spring peanut regional tests, and carries on the production experiment in 2009 spring, and field acceptance passed by peanut professional group of the non-major crop variety appraisal committee of Fujian Province in July the same year. Pod per-mu yield 266.63kg, increases 6.58% compared to the control and per-mu yield seeds 174.3kg, increases 3.54% compared to the control. The seeds have 52.26% crude fat content, protein content 28.34% and middle resistance to the bacterial wilt. The growth period of the Fuhua 4 is about 129 days. Fuhua 3 has big number of flower in earlier period, and percentage of formed pegs and the number of full pods higher the the control. The LAI of flowering and pegging stage, bearing pod stage and pod setting stage is all higher then the control, except the Seedling stage. The NAR of Seedling stage, bearing pod stage and yield-forming stage 、accumulation rate in pod setting stage and economical coefficient of yield-forming are higher than the control. Maintains certain percentage of dry matter accumulation and the high economical coefficient is a high production important physiological foundation. Many dry materials enrich the sink, and the good coordination between the sink and source, thus the output is high.
