Comprehensive evaluation and analysis of rape regional test varieties in Henan Province
Abstract: It is vitally important to study the high yielding varieties, stability and adaptability of different area in the rape regional test. This study which used the test data of rape regional of Henan province in 2011 and 2012 , was set 13 good testing varieties of rape and one control rape as the research material, the annual testing varieties test points one set of experiment.The research material was analyced in the method of balance for crop variety regional test data , and through analysis for one year more variance and F test by DPS data processing system to each point summary data, then analysis resault of the varieties of yield and its components of variance components was got, and we got the stability testing varieties at the same time. The results showed that in the qualities area, oil content of double rape 092 reached 46.60%, belonging to high oil variety; As tooil production, the production of miscellaneous 2803 is the highest; what's more, miscellaneous 2803 has advantage in agronomic traits.All in All,the miscellaneous is outstanding in the high yielding varieties, stability and adaptability of different area in the rape regional test.

河南省油菜区域试验品种的综合评价分析引言
随着我国杂交油菜育种进程的加快，对我国油菜区域试验品种进行遗传多样性的分析，可以使我们对现有的油菜品种遗传结构有一个清醒的认识，为评估基因资源的开发前景提供重要的数据信息，同时可以对优良品种的培育提供帮助。油菜育种发展迅速,新的品种不断被推出，每年都有上百个油菜新品种参加审定推广，因此品种鉴定与评价分析显得至关重要。
品种区域试验是指通过统一规范的要求进行试验，是对农作物品种的丰产性、适应性、抗逆性、稳产性和品质进行全面鉴定的重要手段。根据品种在区域试验中的表现，结合各种性状鉴定和品质结果，对品种进行综合评价。作物品种的许多性状都存在基因与环境的互作，这是品种性状稳定性差异的根源。任何作物及其任何品种都具有区域的适应性，在丰产性好的前提下, 稳定性好的品种适应性广，可推广的范围就大；而稳定性不理想的品种则只能在其适应的区域和生产条件下推广应用。品种区域试验是评价品种的科学依据，也是品种审定推广以及品种科学布局的重要依据。本文对河南省油菜区试中的品种进行高产稳产性分析，以及品质及主要农艺性状的表现，为筛选高产优良油菜育种品种提供依据[1]。
