Pistacia atlantica Desf. subsp. mutica is widely distributed in the Zagros Mountains in Iran and its fruits are used as food. In the present study, the morphological and pomological variation of naturally grown male and female genotypes of this species was investigated. Considerable variations were observed among male and also among female genotypes studied based on the characters measured. Leaf length ranged from 11.03 to 17.67 cm in male genotypes and also from 11.98 to 16.14 cm in female genotypes. Furthermore, leaf width varied from 7.32 to 13.08 cm in male genotypes and from 9.18 to 13.31 cm in female genotypes. Inflorescence length ranged between 4.62 and 5.83 cm in male genotypes and between 5.05 and 9.04 cm in female genotypes. Also, 100-nut weight varied from 13.74 to 22.81 g with an average of 16.09, while 100-kernel weight ranged from 2.11 to 3.60 g with an average of 2.65 in female genotypes. Leaf length was significantly and positively correlated with leaf width. Furthermore, 100-kernel weight was positively and significantly correlated with leaf and nut dimensions. Principal component analysis showed that the characters measured accounted for 77.41% of the total variance in male genotypes and also 83.24% of the total variance in female genotypes. The genotypes studied showed high variation based on the characters recorded. The wide adaptation of P. atlantica Desf. subsp. mutica highlights its potential as a genetic resource for pistachio breeding for resistance to abiotic and biotic stresses such as drought. The current findings may be useful to select conservation strategies and genetic improvement of the species studied.

Pistacia atlantica Desf 雄性和雌性基因型的形态学和果树学特征。亚种 穆蒂卡

Pistacia atlantica Desf. 亚种 mutica广泛分布于伊朗的扎格罗斯山脉,其果实被用作食物。在本研究中,研究了该物种自然生长的雄性和雌性基因型的形态学和果树学变异。在基于测量的特征研究的男性和女性基因型之间观察到相当大的变化。雄性基因型的叶长范围为 11.03 至 17.67 厘米,雌性基因型的叶长范围为 11.98 至 16.14 厘米。此外,叶宽在雄性基因型中从 7.32 到 13.08 厘米不等,在雌性基因型中从 9.18 到 13.31 厘米不等。雄性基因型的花序长度介于 4.62 和 5.83 厘米之间,雌性基因型的花序长度介于 5.05 和 9.04 厘米之间。此外,100 粒的重量从 13.74 到 22.81 克不等,平均为 16.09,而 100 粒的重量在 2 之间。11 至 3.60 g,女性基因型平均为 2.65。叶长与叶宽呈显着正相关。此外,百粒重与叶片和坚果尺寸呈显着正相关。主成分分析表明,所测性状占男性基因型总方差的77.41%,占女性基因型总方差的83.24%。研究的基因型显示出基于记录的特征的高度变异。P. atlantica Desf 的广泛适应。亚种 mutica 突出了其作为开心果育种遗传资源的潜力,可抵抗干旱等非生物和生物胁迫。目前的发现可能有助于选择所研究物种的保护策略和遗传改良。65 在女性基因型中。叶长与叶宽呈显着正相关。此外,百粒重与叶片和坚果尺寸呈显着正相关。主成分分析表明,所测性状占男性基因型总方差的77.41%,占女性基因型总方差的83.24%。研究的基因型显示出基于记录的特征的高度变异。P. atlantica Desf 的广泛适应。亚种 mutica 突出了其作为开心果育种遗传资源的潜力,可抵抗干旱等非生物和生物胁迫。目前的发现可能有助于选择所研究物种的保护策略和遗传改良。65 在女性基因型中。叶长与叶宽呈显着正相关。此外,百粒重与叶片和坚果尺寸呈显着正相关。主成分分析表明,所测性状占男性基因型总方差的77.41%,占女性基因型总方差的83.24%。研究的基因型显示出基于记录的特征的高度变异。P. atlantica Desf 的广泛适应。亚种 mutica 突出了其作为开心果育种遗传资源的潜力,可抵抗干旱等非生物和生物胁迫。目前的发现可能有助于选择所研究物种的保护策略和遗传改良。百粒重与叶片和坚果尺寸呈显着正相关。主成分分析表明,所测性状占男性基因型总方差的77.41%,占女性基因型总方差的83.24%。研究的基因型显示出基于记录的特征的高度变异。P. atlantica Desf 的广泛适应。亚种 mutica 突出了其作为开心果育种遗传资源的潜力,可抵抗干旱等非生物和生物胁迫。目前的发现可能有助于选择所研究物种的保护策略和遗传改良。百粒重与叶片和坚果尺寸呈显着正相关。主成分分析表明,所测性状占男性基因型总方差的77.41%,占女性基因型总方差的83.24%。研究的基因型显示出基于记录的特征的高度变异。P. atlantica Desf 的广泛适应。亚种 mutica 突出了其作为开心果育种遗传资源的潜力,可抵抗干旱等非生物和生物胁迫。目前的发现可能有助于选择所研究物种的保护策略和遗传改良。男性基因型总变异的 41%,女性基因型总变异的 83.24%。研究的基因型显示出基于记录的特征的高度变异。P. atlantica Desf 的广泛适应。亚种 mutica 突出了其作为开心果育种遗传资源的潜力,可抵抗干旱等非生物和生物胁迫。目前的发现可能有助于选择所研究物种的保护策略和遗传改良。男性基因型总变异的 41%,女性基因型总变异的 83.24%。研究的基因型显示出基于记录的特征的高度变异。P. atlantica Desf 的广泛适应。亚种 mutica 突出了其作为开心果育种遗传资源的潜力,可抵抗干旱等非生物和生物胁迫。目前的发现可能有助于选择所研究物种的保护策略和遗传改良。
