以61个‘范艾斯汀’海棠（Malus spectabilis ‘Vans Eseltine’）自由授粉子代的2年生嫁接苗为实验材料，并以同年嫁接的母本‘范艾斯汀’海棠嫁接苗为对照，对‘范艾斯汀’海棠半同胞家系及母本苗期的生长、观赏和抗性指标进行观测，采用Gompertz模型拟合子代年生长过程，采用层次分析（AHP）法对‘范艾斯汀’海棠半同胞家系进行综合评价，旨在制定适宜的育苗措施，同时选育出生长迅速且表型优良的子代。结果显示：‘范艾斯汀’海棠半同胞家系的苗高和地径年生长均符合“S”型曲线，呈“慢—快—慢”的生长节律，反映了“生长前期（3月中至5月中）—速生期（4月初至9月初）—生长后期（5月中至11月中）”的生长过程，对各生长期应给予不同的育苗措施。‘范艾斯汀’海棠半同胞家系速生期可分为前期速生型（4月初至4月中）、中期速生型（4月中至5月初）和后期速生型（5月初至5月中）。不同个体苗高和地径速生期始末差异明显，呈现异速生长现象。其中，85%的子代苗高速生期属于前期、中期速生型，91%的子代地径速生期属于中期、后期速生型。V39、V49、V21、V27和V40 5个子代生长迅速，苗高（202.0～226.0 cm）和地径（18.96～22.04 mm）均高于母本（苗高和地径分别为197.9 cm和16.14 mm），分枝数（14～38）多于母本（9），新叶均为紫红色或棕红色，树皮光滑或较光滑。综上所述，Gompertz模型可预测‘范艾斯汀’海棠半同胞家系的苗期生长特性随时间的变化趋势，了解子代的年生长规律；V39、V49、V21、V27和V40 5个子代综合评价得分较高，是优良的‘范艾斯汀’海棠子代单株，今后可加强其观赏性评价，实现观赏与长势俱佳的育种目标。

 Taking 61 two-year-old grafted seedlings of free pollinated progenies of Malus spectabilis ‘Vans Eseltine’ as experimental materials, and grafted seedlings of the female parent M. spectabilis ‘Vans Eseltine’ grafted in the same year as the control, the growth, ornamental, and resistance indexes of the halfsib families and female parent of M. spectabilis ‘Vans Eseltine’ were observed during the seedling stage, the annual growth process of the progenies was fitted by using Gompertz model, and the halfsib families of M. spectabilis ‘Vans Eseltine’ were comprehensively evaluated by using analytic hierarchy process （AHP） method, the aim was to formulate an appropriate seedling cultivation measures and simultaneously select and breed progenies with rapid growth and excellent phenotypic traits. The results show that the annual growth of seedling height and ground diameter of the half-sib families of M. spectabilis ‘Vans Eseltine’ both conform. to a “S”-shaped curve, exhibiting a “slow-fast-slow” growth rhythm, this reflects the growth process of “early growth stage （from mid-March to mid-May）-fast-growing stage （from early April to early September）-late growth stage （from mid-May to mid-November）”, and different seedling cultivation measures should be implemented for each growth stage. The fast-growing stage of the half-sib families of M. spectabilis ‘Vans Eseltine’ can be divided into early fast-growing type （from early April to mid-April）, mid-term fast-growing type （from mid-April to early May）, and late fast-growing type （from early May to mid-May）. There are obvious differences in the initial and terminal fast-growing stage of seedling height and ground diameter between different individuals, showing an allometric growth phenomenon. Among them, 85% of the progenies belong to the early and mid-term fast-growing types in seedling height, while 91% of the progenies belong to the mid-term and late fast-growing types in ground diameter. The five progenies V39, V49, V21, V27, and V40 grow rapidly, and their seedling height (202.0-226.0 cm)  and ground diameter （18.96-22.04 mm) are both higher than those of the female parent （seedling height and ground diameter are 197.9 cm and 16.14 mm, respectively）, while the number of branches （14-38） is larger than that of the female parent （9）, their young leaves are all fuchsia or brownish red, and their barks are smooth or relatively smooth. In conclusion, the Gompertz model can predict the variation tendency of growth characteristics of the half-sib families of M. spectabilis ‘Vans Eseltine’ with time during seedling stage, and provide insights into the annual growth rules of the progenies; the comprehensive evaluation scores of five progenies V39, V49, V21, V27, and V40 are relatively high and are considered as excellent progeny individuals of M. spectabilis ‘Vans Eseltine’, and their ornamental evaluation can be further strengthened in the future to achieve the breeding goal of both excellent ornamental and growth characteristics.
