摘要:

【目的】通过对山西谷子种质资源进行系统耐瘠性鉴定与综合评价,筛选优异耐瘠种质,建立评价模型,筛选鉴定指标,为谷子耐瘠品种的高效选育提供理论依据与方法支撑。【方法】以617份山西谷子地方品种为试验材料,于2023—2024年分别在太原(23TY,24TY,瘠薄胁迫)和东阳(23DY,24DY,正常肥力)种植,测定节数、茎粗、穗粗、株高、颈长、穗长、叶长、叶宽、穗重、穗粒重、千粒重11个指标,通过正态分布检验、耐瘠薄系数差异分析、相关性分析、聚类分析和回归分析等方法,对谷子种质资源的耐瘠性进行综合评价鉴定。【结果】各农艺性状的变异幅度存在差异,变异系数为9.23%—48.05%,其中,23TY叶宽的变异系数最小,为9.23%;24TY穗粒重的变异系数最大,为48.05%。K-S检验结果表明,除了节数、穗长、叶宽和穗重之外,其他性状在不同环境中均存在不同程度的正态性分布(P>0.05)。通过对两年两点4个环境中测量的表型值进行相关性分析,穗重和穗粒重呈显著正相关,且相关系数最大,其次是节数与株高、穗长与叶长。此外,颈长与节数在23TY、23DY呈显著负相关;叶长与株高、节数在23TY呈显著负相关;颈长与穗粗在23TY呈显著负相关;颈长与株高在23DY呈显著负相关。主成分分析结果表明,将11个表型性状转化为2个综合指标,累积解释率达到59.68%。利用隶属函数法计算综合耐瘠薄评价值(D值),进行聚类分析,按照耐瘠薄强弱分为3种类型,第Ⅰ类不耐瘠品种有13个,D值为0.09—0.28;第Ⅱ类中度耐瘠品种包括595个,D值为0.40—0.81;第Ⅲ类耐瘠品种有9个,D值为0.84—0.93,其中,来源于阳泉市的毛软谷为耐瘠性最强的品种。采用多元回归分析方法,建立耐瘠薄预测评价模型Y=-0.031+0.129X9+0.167X10+0.141X6+0.233X8+0.205X4R2=0.951,P<0.001)。【结论】采用多元统计分析方法可有效评价与预测谷子种质的耐瘠薄性,筛选出株高、穗长、叶宽、穗重、穗粒重5个表型性状作为耐瘠薄鉴定评价指标,鉴定到阳泉市的毛软谷为耐瘠性最强的种质。

Abstract:

【Objective】This study aimed to select superior barren-tolerant germplasm, establish an evaluation model, and identify diagnostic indicators in foxtail millet germplasm resources from Shanxi, so as to provide the theoretical basis and methodological support for the efficient breeding of barren-tolerant foxtail millet varieties. 【Method】617 local foxtail millet varieties were used as experimental materials. Trials were carried out under low-fertility stress in Taiyuan (23TY, 24TY) and under normal fertility conditions in Dongyang (23DY, 24DY) from 2023 to 2024. Eleven indicators were measured, including stem node number (SNN), stem diameter (SD), panicle diameter (PD), plant height (PH), peduncle length (PeL), panicle length (PaL), leaf length (LL), leaf width (LW), spike weight per plant (SWP), grain weight per plant (GWP), and thousand-grain weight (TGW). A comprehensive evaluation and identification were carried out using multiple analytical methods, such as normal distribution test, barren tolerance coefficient difference analysis, correlation analysis, cluster analysis, and regression analysis. 【Result】The results showed significant differences in agronomic traits, with coefficients of variation ranging from 9.23% to 48.05%. Specifically, the coefficient of variation for LW in 23TY was the smallest (9.23%), while the coefficient for GWP in 24TY was the largest (48.05%). K-S test results indicated that, except for SNN, PaL, LW, and SWP, other traits showed varying degrees of normal distribution in different environments (P>0.05). Correlation analysis showed that SWP and GWP exhibited a significant positive correlation with the highest correlation coefficient, followed by SNN with PH, PaL with LL. In addition, PeL and SNN showed a significant negative correlation in 23TY and 23DY; LL and PH, LL and SNN, PeL and PD had a significant negative correlation in 23TY; and PeL was significantly negatively correlated with PH in 23DY. Principal component analysis results revealed that 11 phenotypic traits were converted into 2 comprehensive indices, with a cumulative explanation rate of 59.68%. Using the membership function method calculated the barren tolerance (D value), and cluster analysis was performed. The varieties were classified into three categories: Class I included 13 barren-sensitive varieties with D values ranging from 0.09 to 0.28; Class Ⅱ included 595 moderately barren-tolerant varieties with D values ranging from 0.40 to 0.81; Class Ⅲ included 9 barren-tolerant varieties with D values ranging from 0.84 to 0.93. Maorangu was the most barren-tolerant variety from Yangquan city. Through multiple regression analysis, a predictive evaluation model for barren tolerance was established: Y=-0.031+0.129X9+0.167X10+0.141X6+0.233X8+ 0.205X4 (R2=0.951, P<0.001). 【Conclusion】Using multivariate statistical analysis methods, it is reliable to evaluate and predict the barren tolerance of foxtail millet germplasm. Five phenotypic traits are selected as evaluation indicators for barren tolerance: plant height, panicle length, leaf width, spike weight per plant, grain weight per plant. The Maorangu variety from Yangquan city was the strongest barren tolerance.
