三、搞好油莱县繁种子基地的关键性技术措施 (一)选准品种。选准品种是建立油菜县繁种子基地的前提条件。品种选择应立足于原有基础兼顾发展要求。但品种的性状,特别是属于数量遗传、易受环境因素影响的经济性状,常是由其内在的基因型同与之相适应的外界条件相互作用结果而构成的表现型,反应出一定的生产力和适应性。因此即使在一个县的范围内也还存在品种的合理布局问题,应根据其自然条件,耕作制度和生产特点,通过良种区域化鉴定和生产调查,确定不同生态区域的适宜油菜品种。并要以繁殖当家品种为主,照顾搭配品种。
Third, to do a good job in the base of oil seedling rapeseed key technical measures (A) selected varieties. Selection of prospective varieties is the establishment of rapeseed county seed base of prerequisites. Variety selection should be based on the original basis of both development requirements. However, the traits of breeds, especially the economic traits that are genetically inherited and susceptible to environmental factors, are often phenotypes formed by the interaction between their intrinsic genotypes and the external conditions that are compatible with them, reflecting a certain productivity And adaptability. Therefore, even within the scope of one county, there is still the problem of rational distribution of varieties. According to their natural conditions, farming system and production characteristics, the appropriate rapeseed varieties in different ecological regions should be identified through the identification and production survey of fine varieties. And to breed the main varieties, take care of with varieties.
