Almonds (Prunus dulcis Mill.) are generally relative drought-resistant crops. In the present study, morphological and pomological characteristics of 84 non-irrigated seedling-originated trees were evaluated to identify the genotypes best adapted to drought. Based on the characters recorded, significant differences were observed among the genotypes. Spring frost resistance was high in 17 out of 84 genotypes due late-blooming time. Nut weight ranged between 1.40 and 12.90 g with an average of 5.76, while kernels weighted between 0.10 and 3.10 g with an average of 1.35. Principal component analysis (PCA) revealed that 74.76% of total variances were explained by 10 components and confirmed the appropriateness of applying pomological traits to select the superior genotypes. Unweighted pair group method of arithmetic average (UPGMA) method and Euclidean distances-based analysis on all the recorded characters divided the genotypes into two major clusters. Based on ideal values of commercially important characteristics such as fruit yield, nut weight, shell hardness, kernel shape, kernel weight, and kernel taste, 11 genotypes were promising and are recommended for cultivation under drought condition.

非灌溉杏仁 (Prunus dulcis Mill.) 树的表型和果树学特征以选择优良基因型

杏仁 ( Prunus dulcis )Mill.) 通常是相对抗旱的作物。在本研究中,评估了 84 棵非灌溉苗木的形态学和果树学特征,以确定最适合干旱的基因型。根据记录的特征,在基因型之间观察到显着差异。由于开花时间晚,84个基因型中有17个的春季抗冻性较高。坚果重量在 1.40 至 12.90 克之间,平均为 5.76,而仁重在 0.10 至 3.10 克之间,平均为 1.35。主成分分析 (PCA) 显示,74.76% 的总方差由 10 个成分解释,并证实了应用果树学性状选择优良基因型的适当性。对所有记录的性状进行算术平均(UPGMA)方法和基于欧几里得距离的非加权对组分析将基因型分为两大类。基于果实产量、坚果重量、壳硬度、粒形、粒重和粒味等商业重要特性的理想值,11个基因型是有前景的,被推荐用于干旱条件下的栽培。
