1995年,通过亚蔬中心耐热大白菜引种及其适应性研究,筛选出适合本市栽培和消费的早熟耐热大白菜良种2只。它们均具有耐热.株型矮小.生长期短(55天),叶色深绿、叶厚无毛,叶球筒形、叠抱、色泽黄白、结球紧实,质嫩、纤维少、品质佳,抗病毒病,对霜霉病、软腐病抗性较强等特点。其中,77M(2/3)—46:叶球重0.88公斤,净菜率76.5%,折666.7米~2产量1904.5公斤,比对照早熟5号增广28.0%:62:叶球重0.54公斤,净菜率70.5%,折666.7米~2产量1690.4公斤,比对照早熟5号增产13.6%。
In 1995, through the introduction and adaptability of heat-resistant Chinese cabbage in Asia Vegetable Center, we screened out 2 precocious heat-resistant Chinese cabbage suitable for cultivation and consumption in our city. They all have heat-resistant, short stature, short growth period (55 days), dark green leaves, glabrous leaves, cylindrical leaves, overlapping yellow and white, tight knots, Good quality, anti-virus disease, downy mildew, soft rot resistance and other characteristics. Among them, 77M (2/3) -46: leaf ball weight 0.88 kg, the net vegetable rate of 76.5%, folding 666.7 m ~ 2 yield 1904.5 kg, 28.0% more than the control precocious 5: 62: Rate 70.5%, fold 666.7 m ~ 2 yield 1690.4 kg, compared with the control precocious 5 increased 13.6%.
