摘要
为了提高番茄杂交组合育种选育效率和筛选出适宜宁夏地区露地栽培的综合性状优良的大果番茄杂交组合,以62个露地大果番茄杂交组合为材料,以2个当地主栽品种丰收128(CK1)和美粉869(CK2)为对照,采用变异分析法和主成分分析法对28个表型性状数据进行分析,并对62个杂交组合和对照品种进行综合评价。结果表明,11个植物学性状中叶片长的变异系数最小,为7.73%,萼片形状的变异系数最大,为46.74%;17个果实性状中果形指数的变异系数最小,为6.31%,裂果性的变异系数最大,为43.38%;利用主成分分析法提取到的前10个主成分累积方差贡献率为73.31%,包含了杂交组合表型性状的大部分遗传信息。基于主成分分析与隶属函数法相结合的策略对62个番茄杂交组合进行综合评价,筛选出综合评价值比2个对照品种高的4个番茄杂交组合为AF07、AF46、AF44和AF55。研究结果为宁夏地区越夏露地大果番茄品种选育奠定了理论基础。
In order to improve the efficiency of tomato hybrid combination breeding and screen for large fruit tomato hybrid combinations with excellent comprehensive traits suitable for open field cultivation in Ningxia region.62 hybrid combinations of open field large fruit tomatoes were used as materials,with two main varieties Fengshou 128(CK1)and Meifen 869(CK2)as controls.The data of 28 phenotypic traits were processed and analyzed using variation analysis and principal component analysis.A comprehensive evaluation was conducted on 62 hybrid combinations and control varieties.The results showed that among the 11 botanical traits,the variation coefficient of the leaf length was the smallest,at 7.73%,and the variation coefficient of sepal shape was the largest,at 46.74%.Among the 17 fruit traits,the variation coefficient of fruit shape index is the smallest,at 6.31%,and the variation coefficient of fruit cracking is the largest,at 43.38%.The cumulative variance contribution rate of the top 10 principal components extracted using principal component analysis is 73.31%,which includes most of the genetic information of the phenotypic traits in hybrid combinations.Based on the combination of principal component analysis and membership function method,a comprehensive evaluation was conducted on 62 tomato hybrid combinations.Four tomato hybrid combinations with higher comprehensive evaluation values than the two control varieties were selected as AF07,AF46,AF44 and AF55,with comprehensive evaluation values of 0.76,0.74,0.69,and 0.68,respectively.This study provides a theoretical basis for the breeding of large fruit tomato varieties in the summer open field of Ningxia region.
