一、目前全省育种趋势和现有品种潜力据国内外专家分析,在提高单位面积产量的农业增产技术中,良种作用占20—30％,高的可达50％以上。“七五”期间,在省委、省府的关怀和支持下,我省六大作物育种攻关,共育成通过审定的新品种58个,其中稻、麦、玉、苕四大粮食作物新品种54个。目前已育成并正结束或即将结束省区试和生产示范,近年可提供审定使用的新品种有11个,其中水稻3个、玉米6个、小麦2个。育种进展总体趋势,从不同作物来看,大致可分成三个类型: 一是有显著进展的,主要是玉米、红苕新品种的选育。在产量水平、株型结构和抗性上有突破,已完
First, the current trend of the province’s breeding and the potential of existing varieties According to domestic and foreign experts analysis, in improving the yield per unit area of agricultural production technology, the role of seeds accounted for 20-30%, up to 50% or more. During the “Seventh Five-Year Plan” period, with the care and support of the provincial party committee and the provincial government, 58 breeding varieties passed the validation of new varieties of crops in the province, including the new varieties of rice, wheat, jade and jackal 54. At present, there have been 11 bureaus newly started and ending the trial and production demonstration in the provinces and autonomous regions. Three new rice varieties, 6 maize and 2 wheat, have been approved for use in recent years. The general trend of breeding progress, from different crops point of view, can be divided into three types: First, there have been significant progress, mainly corn, red bream new varieties of breeding. In the level of production, plant type structure and resistance on a breakthrough, has been completed
