序言本文将以提高总产量为前提论述英国小麦育种的方针与展望。三十年来,英国小麦单产增加了一倍。1978年亩产超过666.7斤(农业部关于渔业和食物统计资料,1979)。平均增长率为8.5斤/亩(Austin,1978)。除在1968年和1976年出现低于8斤/亩和在1962、19741978年出现高于8斤/亩的增长率外,这些年均为直线增长。小麦的播种面积也有所增加,因此总产量增加近二倍。在收成最好的1978年,估计总产量可达6.59万吨。食用、饲用小麦自给率述到71%。 Preface This article will be based on the premise of raising the total output of the British wheat breeding guidelines and prospects. For three decades, wheat yields in the United Kingdom have doubled. In 1978 more than 666.7 kg per mu (Ministry of Agriculture on Fisheries and Food Statistics, 1979). The average growth rate was 8.5 kg / mu (Austin, 1978). Except for the below 8 kg / acre in 1968 and 1976 and the increase of more than 8 kg / acre in 1962 and 1974-1978, these years all showed a linear increase. The area planted to wheat has also increased, so total output has nearly tripled. In 1978, the best crop, an estimated total production of 65 900 tons. Edible, feed wheat self-sufficiency rate is reported to 71%.
