Abstract:

The new variety nurtured by sexual hybridization and mixed pedigree selection method, Quanhua 327 as female parent and the International Institute for the Semi-Arid ICGV94449A as male parent in autumn 2001, 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 281.02kg, increases 12.33% compared to the control and per-mu yield seeds 189.65kg, increases 12.65% compared to the control. The seeds have 51.56% crude fat content, protein content 29.08% and susceptibility to the bacterial wilt. The growth period of the Fuhua 4 is about 125 days. Fuhua 4 has moderate amount of flowers, centralized flowering season and high effective flower rate. LAI of the seedling stage and pod setting stage lower than the control, and the etceteras high compared to the control. The NAR of Seedling stage, bearing pod stage and yield-forming stage is higher than the control. The flowering and pegging stage and vegetative growth appear at the same time, when reproductive growth has been relatively strong. Dry matter accumulation and more rapid transfer to the pod in bearing pod stage. Maintains certain percentage of dry matter accumulation and the high economical coefficient is a high production important physiological foundation. There have the big sink and source、the great ratio of sink/source and the good coordination between the sink and source, thus Fuhua 4 has the high yield.
