英国东茂林农业试验站经过十年的努力,已培育出一种没有分枝的苹果树。这种苹果树具有大量花或果实的极短果枝的长枝。它是六十年代在英国Colombie被发现的:是一红色苹果Wijcik演变的后代,Wijcik的主干具有只发生极短枝而不发生分枝的特性。通过Wijcik和多种鲜食苹果品种杂交,它们的后代中一半以上的群体是没有分枝的。目前已经选择了四个品种正在进行推广,观察和繁殖:一个绿色的早熟品种,一个红色和一个绿色的中熟品种以及一个红色的晚熟品种。
After ten years of hard work, the British East Maolin Agricultural Experiment Station has developed an apple tree without branches. This apple tree has long branches of very short fruiting branches with large numbers of flowers or fruits. It was discovered in the 1960s in Colombie, England: a descendant of the evolution of a red Apple Wijcik, whose backbone has the characteristic of having only very short branches without branching. By crossing Wijcik with a variety of fresh apple varieties, more than half of their offspring are unbranched. Four varieties are currently being selected for promotion, observation and breeding: a green precocious variety, a red and a green medium maturing variety and a red late maturing variety.
