The genus Ocimum is very complicated due to the presence of huge morphological variability along with genetic diversity. Basil (Ocimum basilicum L.) has pharmacological properties to treat headaches, coughs, diarrhea, constipation, warts, worms, and kidney malfunction and potential as a therapeutic agent in treating various age‐related diseases. In this study, a total of 74 genotypes were used in 2017 and 61 genotypes were adapted. Among the 61 genotypes, 50 genotypes were sown in 2018. The present investigation composed of basil genotypes was undertaken to characterize the genotypes based on morphological and phenological features, herbs, and essential oil yield of genotypes. A wide range of variations for traits like days to first cutting (56.92–101.6 d), plant height (13.67–71.90 cm), branch number (3.28–19.43 plant−1), fresh herb yields (12.94–274.11 g plant−1), and essential oil yield (0.04–1.71%) were observed and can be useful for breeding purposes. PI 652070 and PI 296391 were found superior with the highest herbs yield as compared with other genotypes. Overall, PI 358469 and Ames 32309 genotypes exhibited the highest essential oil content. A constellation analysis was conducted to investigate the genetic diversity of basil genotypes. According to the constellation plot analysis, 46 basil genotypes and four cultivars were evaluated according to morphological, yield, and International Association for the Protection of New Plant Varieties (UPOV) properties, and most of the basil genotypes and one cultivar (Midnight) were located in the same group. As a result of the constellation plot analysis, Moonlight and Dino cultivars were located in the same group with PI 141198 (Maryland, USA) and genotypes originated from Georgia, Iran, Afghanistan, Ethiopia, and Hungary located in the same main group. Other genotypes of the same origin were found in a different main group.

甜罗勒基因型用于育种的农业形态和表型变异

罗勒非常由于遗传多样性以及复杂庞大的形态差异的存在。罗勒(罗勒罗勒L.)具有治疗头痛,咳嗽,腹泻,便秘,疣,蠕虫和肾功能不全的药理特性,并具有作为治疗各种年龄相关疾病的治疗剂的潜力。在这项研究中,2017年共使用了74种基因型,并对61种基因型进行了改编。在61种基因型中,2018年播种了50种基因型。本研究由罗勒基因型组成,根据基因型,物候特征,草药和基因型的精油产量对基因型进行表征。各种性状的变异范围很广,例如初剪的天数(56.92–101.6 d),株高(13.67–71.90 cm),枝数(3.28–19.43植物-1),新鲜药草产量(12.94–274.11 g植物-1),并观察到精油收率(0.04–1.71%),可用于育种目的。发现PI 652070和PI 296391与其他基因型相比具有更高的草药产量,具有更高的药效。总体而言,PI 358469和Ames 32309基因型表现出最高的精油含量。进行星座分析以研究罗勒基因型的遗传多样性。根据星座图分析,根据形态,产量和国际植物新品种保护协会(UPOV)特性,评估了46种罗勒基因型和4个品种,并且找到了大多数罗勒基因型和1个品种(Midnight)。在同一组中。作为星座图分析的结果,Moonlight和Dino品种与PI 141198位于同一组(马里兰州,美国)和基因型分别来自同一主要群体中的格鲁吉亚,伊朗,阿富汗,埃塞俄比亚和匈牙利。在不同的主要人群中发现了相同起源的其他基因型。
