前言我省低温、少雨、无霜期短,白菜粮食都是一年一作,白菜生产与粮争地。白菜是冬季的主要蔬菜,储藏达6个月之久,尤其广大的农村冬季不能由外调菜,对白菜更为需要。农村粪肥多用在粮田上,而白菜则粪少,栽培条件差,因此要求具有早熟,能与麦茬复种,高产、质优、耐贮、耐旱、耐瘠薄等特性的白菜新品种。但是白菜有些特性连锁遗传很强,如;质优不抗病;早熟不耐贮;早熟不高产等。用一般的选育方法很难
Preface Our province low temperature, less rain, frost-free period is short, cabbage food is a year, cabbage production and grain dispute. Cabbage is the main winter vegetables, storage up to 6 months, especially in the vast rural winter can not be changed by the dishes, cabbage is more needed. Rural manure is more used in the grain field, while cabbage is less manure, poor cultivation conditions, requiring a precocious, with stubble, high yield, high quality, storage, drought, barren and other characteristics of the new cabbage varieties. However, some characteristics of cabbage genetic inheritance is strong, such as; quality is not resistant to disease; precocious stale storage; early maturity is not high yield and so on. With the general breeding method is difficult
