豫花4号(原郑7888)系河南省农科院经济作物研究所利用豫花一号作母本,南召不拖秧作父本,于1986年杂交选育而成的花生新品种。省区域试验和生产试验结果表明,该品种具有高产、优质、早熟、抗病等特点,是麦套夏播种植的良好接班品种。一、产量表现1987年该品种在全省区域预备试验中,籽仁亩产200公斤,比对照1徐州68—4增产16.3%,比同类型的对照2花28增产13.6%。1988—1989年省区域试验两年10点次平均亩产籽仁175公斤,比对照花28增产11.5%,10点次中,籽仁产量8处第1位,两处第2位。豫花4号1989年参加省生产试验,12 Yuhua 4 (formerly Zheng 7888) Department of Henan Province Academy of Agricultural Sciences Institute of Economic Crops on the 1st using Yuhua as a female parent, Nanzhao do not pull seedling as the father of the hybrid in 1986, a new breed of peanut. Provincial regional trials and production test results show that the varieties with high yield, high quality, early maturity, disease resistance and other characteristics of summer wheat planting is planted good succession varieties. First, the yield performance 1987 varieties of the region in the province to prepare the test, seed kernel yield 200 kg, 68-4 Xuzhou than the control 1 to increase 16.3%, 28 flowers than the same type of control 28 yield 13.6%. In 1988-1989, the provincial regional trial averaged 175 kg of seed kernel per mu at 10 o’clock in two years, which increased 11.5% compared with the control flower 28, and at 10 o’clock, the yield of seed kernel was the first in 8 places and the second in two places. Yuhua 4 in 1989 to participate in provincial production test, 12
