基于HIDAP系统的马铃薯高代品系多性状综合分析

Comprehensive analysis of potato high generation strains multiple traits based on HIDAP system

为了更便捷清楚地将马铃薯新品种选育中高代品系的多性状因子进行综合分析评价,本文利用国际马铃薯中心开发的高交互性数据分析育种软件(HIDAP),对参与2020年定西市马铃薯多点试验的14个高代品系在5个试点的产量、薯块数量、商品薯率表现情况利用AMMI模型、GGE双标图、Tai稳定性模型结合方差显著性分析、联合回归等方法进行分析筛选评价。在AMMI分析图中,高代品系0934-62的产量、单株薯块数、商品薯率在垂直方向上的IPCA绝对值较小且在水平方向靠近最右侧;结合GGE双标图,高代品系0934-62、1026-2、14137-20处于水平线以上较高位置,其中品系0934-62位于水平线以上最远距离;在Tai模型分析中,根据高代品系在产量、块茎数量、商品薯率中α与λ参数的分布范围,可知稳定性高的品系为0934-62、1026-2、1281-191。综合各分析结果可知,在参试的14个品系中,高代品系0934-62在产量、薯块数量、商品薯率中的稳定性与丰产性表现突出,高代品系1026-2、1281-191、14137-20表现良好,品系1205-5表现较差。HIDAP软件通过自身所具有的评价系统利用多个数据分析模型,能够有效管理大量育种材料信息进行分析筛选并及时淘汰无用信息,减少成本支出,节约试验资源。

The purpose of this study was to comprehensively analyze and evaluate the multi-trait factors of high generation varieties in aspect of new potato variety breeding.The breeding software(HIDAP)developed by the international potato center was used.The yield,total number of potato tubers and marketable tubers rate for 14 potato high generation strains of multi-point test in five sites of Dingxi City were analyzed using the analysis of variance significance,AMMI model,the GGE-biplot and Tai stability in 2020.In the AMMI analysis diagram,the IPCA absolute values of yield,the number of tubers per plant and marketable tubers rate of high-generation varieties 0934-62 in the vertical direction were small and close to the right in the horizontal direction.Combined with the GGE biplot,the high-generation varieties 0934-62,1026-2 and 14137-20 were in the higher position above the horizontal line,and the high-generation variety 0934-62 was the farthest distance above the horizontal line.In the Tai model analysis,theαandλparameter distribution range of yield,the total number of potato tubers and marketable tubers rate of high-generation varieties were combined,and the varieties with high stability were 0934-62,1026-2 and 1281-191.The results showed that among the 14 potato strains tested,the high generation variety 0934-62 had an outstanding performance in aspect of yield,the total number of potato tubers and marketable tubers rate.High generation varieties 1026-2,1281-191 and 14137-20 showed better performance,while the high generation variety 1205-5 showed poor yield and stability compared with other varieties.HIDAP software effectively helped breeders manage a large amount of breeding material information,conduct analysis and screening,and timely eliminate through its own evaluation system and use of multiple data analysis models,to reduce the costs and save experimental resources.
