Abstract:Abstract [Objective] In order to understand the diversity of the fruit and seed traits (FSTs) of Phoenix dactylifera, and primarily to determine superior individual plants in the introduced P. dactylifera population in Yuanjiang, Yunnan Province, with to further study and provide a basis for breeding high-quality varieties of the species, the FSTs of the 32 P. dactylifera plants introduced in Yuanjiang were analyzed. [Methods] The 11 parameters of the 32 P. dactylifera plants were measured and calculated. The methods of variance analysis, Shannon?Wiener index, correlation analysis and principal component analysis were employed to interpret the diversity, stability of the parameters involved correlation between the parameters and comprehensive scores of the FSTs. [Results] The mean transverse and longitudinal diameters (TDs and LDs), single fruit dry mass (SFDMs), and edible rates of individual fruit (ERIF) of the 32 P. dactylifera plants were 1.9-2.7, 2.9-4.2 cm, 1.9-5.6 g/fruit, and 77.8%-94.9%, respectively; wherein, the coefficient of variation (CV) for fresh seed weight (FSW) was the highest (29.9%), followed by single fruit dry mass(SFDM; 29.7%), and the CV of the ERIF was the lowest (5.3%) in this study, showing relative stability; the SFDM was significantly positively correlated with fruit shape and seed shape index (P<0.05), and positively correlated with other parameters (P<0.01). The edible rate was significantly negatively correlated with fruit moisture content, the TD and LD, seed fresh weight, and seed moisture content (R= -0.635? -0.207, P<0.01).; A comprehensive score of ≥1.000 was identified as the breeding standard for improved varieties, with a total of 5 plants selected from 32 individual study plants, which accounting for 15.6% of the total number of plants. [Conclusion] The diversity of individual P. dactylifera FST was extremely rich, and it had a basis of selecting and breeding superior individual plant; wherein, numbers 1~4 and 11 could be objects as superior individual plant selection for further continuous observation and analysis, ultimately determining the stability of their superior traits. The proportion of superior individual P. dactylifera plant in the population was relatively low, and the breeding of superior varieties is of great significance for improving their yield and output value.
