基于层次分析法和GGE双标图对引进马铃薯种质资源的综合评价

基于层次分析法和GGE双标图法对引进于国际马铃薯中心的97份马铃薯种质资源的主要农艺性状以及适应性、稳定性、丰产性等方面进行综合分析,筛选与鉴定优良可利用种质资源,同时为构建马铃薯种质资源的综合评价体系提供理论依据。结果表明,农艺性状、产量性状和品质性状所占权重大小为0.075、0.70和0.23,其中农艺性状中株高和茎粗所占权重为0.38和0.29,产量性状中产量权重为0.73,品质性状中干物质含量和蛋白质含量权重分别为0.4和0.2。C77和C51适合在甘肃省白银市景泰地区推广种植,C116、C89、C27、C66和C98在甘肃省定西市地区适应性强;参试品系稳定性大小为C49C46C116C112C93;丰产性为C89C116C93C97C112C49C46C67。层次分析法与GGE双标图综合分析可知:C46、C49、C112、C116综合表现较好,可以作为优良品系参加品种审定试验,也可以作为亲本材料。层次分析法和GGE双标图相结合可以作为引进马铃薯种质资源综合评价体系的标准。

Comprehensive Evaluation of Introduced Potato Germplasms Resources Based on the Analytical Hierarchy Process and GGE-Biplot

97 potatoes germplasms resources that were introduced from International Potato Center.Their main agronomic traits were evaluated based on analytical hierarchy process analysis and adaptability,stability and mean were analysed using GGE-biplot (genotype and genotype × environment) analysis.This study is to screen potato germplasm resources that are suitable for planting in Gansu Province and provide theoretical foundations for establishing an evaluation system for introduced potato germplasm resources.The results showed that agronomic traits,yield traits and quality traits weight of 0.075,0.70 and 0.23,respectively,while plant height and stem diameter weight of 0.38 and 0.29 in agronomic traits,respectively.Yield weight of 0.73 in yield traits,dry matter and protein content weight of 0.40 and 0.20 in quality traits,respectively.C77 and C51 were suitable for planting in Jingtai,Baiyin,Gansu Province.C116,C89,C27,C66 and C98 had a strong adaptability in Dingxi,Gansu Province.The stability of potato germplasm resources were C49 ＞ C46 ＞ C116 ＞ C112 ＞ C93.The mean of potato germplasm resources were C89 ＞ C116 ＞ C93 ＞ C97 ＞ C112 ＞ C49 ＞ CA6 ＞ C67.C46,C49,C112 and C116 could participate in regional trials and be useful for selecting hybrid parents by using analytical hierarchy process and GGE-biplot analysis.Analytical hierarchy process and GGE-biplot analysis could be regarded as standards for evaluating introduced potato germplasm resources.
