Abstract:

【Objective】 The main aim of this study was to explore the methods of evaluating shade-tolerance, analyze the shade-tolerance of peanut in different genotypes, screen suitable identification indexes of shade tolerance, and establish an evaluation model of shade tolerance, so as to provide some theoretical support for screening of shade-tolerance resources and variety breeding of peanut. 【Method】 Qiannuo 868 was selected as the corn variety, and under the conditions of corn-peanut intercropping system and net cropping peanut, thirty peanut cultivars (lines) were treated in the field experiment. Net photosynthetic rate (X13), stomatal conductance (X14), intercellular CO2 concentration (X15) and transpiration rate (X16) of peanut leaves were measured at the pod stage of peanut. The main stem height (X1), side branch length (X2), total branch number (X3), effective branch number (X4), plant pod number (X5), mature pods per plant number (X6) and yield per plant (X11) were measured in the peanut mature stage. The 100-pod weight (X7), kernel weight of 100 fruiting (X8), 100-kernel weight (X9), shelling percentage (X10) and plot yield (X12) were measured after harvesting and drying of peanut seed. 【Result】 The variation range of shade tolerance coefficient of each single index was different in different peanut varieties (lines). The 16 single indicators were converted into 5 independent comprehensive indicators through principal component analysis, and their contribution rates respectively were 33.860%, 26.666%, 11.176%, 8.471% and 6.954%, representing the information of 87.127% of all data. Through membership function, the largest membership function values of comprehensive indexes CI1-CI5 respectively were 6-2, Tianfu 29, 201150118A, 201240413 and Minhua 6. The thirty peanut varieties (lines) were divided into 3 categories: the first category was shade tolerance type, including 11 varieties (lines); the second category was moderate shade tolerance type, including 18 varieties (lines); the third category was sensitive type, including 1 variety (line). The optimal mathematical model of peanut shade tolerance evaluation was established, namely D=0.741+0.576X9+0.507X11+ 0.298X13+0.272X12+0.406X10 (R2=0.990), and its accuracy was higher than 93.18%. Then, 5 indexes for peanut shade tolerance identification were selected: 100-kernel weight, yield per plant, net photosynthetic rate, plot yield and the ratio of shelled. The shade tolerance type peanut had a higher net photosynthetic rate, higher 100-kernel weight, yield per plant, plot yield and shelling percentage, while the sensitive type peanut were the opposite. 【Conclusion】 It was relatively scientific to evaluate and analyze the shade tolerance of peanut by multivariate statistical analysis. 30 peanut varieties (lines) were divided into three categories: shade tolerance type, moderate shade tolerance type, and sensitive type. 100-kernel weight, shelling percentage, yield per plant, plot yield and net photosynthetic rate could be used as the indexes to identify the shade tolerance of peanut. The comprehensive evaluation value of shade tolerance could be calculated to predict peanut shade tolerance by measuring the five indexes under the same conditions.
