春夏秋冬一年四季,上海市民都能吃到新鲜的甘蓝。甘蓝周年生产、周年供应的目标已经达到了。这一目标的实现,凝集了科研工作者的心血,上海市农业科学院园艺所副研究员施维钧和她的甘蓝育种课题组,为此奋斗了20余年,作出了重要的贡献。从70年代起她们相继育成了11月至翌年2月上市的寒光甘蓝;4至5月上市的争春甘蓝;6月上市的105×黄苗甘蓝;7至11月上市的夏光甘蓝,基本完成了甘蓝周年生产的杂优品种配套。1992年施维钧和她的甘蓝育种课题组又成功地选育出初春和超夏两个甘蓝新品种(已通过专家验收)。初春甘蓝耐寒性特强,2至3月份上市,比常规品种四月慢甘蓝增产40％以上;超夏甘蓝耐热性超过夏光甘蓝,增产效果极为显著,是夏光甘蓝的更新换代品种。
Spring, summer, autumn and winter all year round, Shanghai citizens can eat fresh cabbage. Cabbage anniversary production, the annual supply target has been reached. The realization of this goal has brought together the scientific and technological workers’ efforts. Shi Weijun, an associate researcher at the Horticultural Institute of Shanghai Academy of Agricultural Sciences, and her team of cabbage breeding have fought for more than 20 years and made important contributions. From the 70s onwards, they have successively cultivated the cold shrooms marketed from November to February of the following year; the spring cabbage marketed from April to May; the 105 × yellow sprouts marketed in June; the summer broccoli marketed from July to November, Completed the annual production of miscellaneous varieties of cabbage matching. In 1992, Schweitzer and her team of cabbage breeding successfully bred two new varieties of cabbage in early spring and super summer (which have passed the acceptance of experts). Early spring cabbage cold tolerance exceptionally strong, listed from March to March, than the conventional varieties in April more than 40% of slow-growing cabbage; super-summer cabbage heat-resistant than the summer broccoli, yield is extremely significant, is the replacement of summer cabbage varieties.
