The present investigation explores the variability of populations belonging to different regions. Variability among 74 genotypes for thirty-seven traits (29 quantitative and 8 qualitative) were studied to ascertain the population structure of the . Among the agro-morphological traits, wide range of variability was recorded in tuber shape, tuber colour, seed shape, seed colour, growth habit, leaf shape, leaf colour, umbel shape, umbel colour, plant height (22.90-96.52 cm), primary branches plant (1-6), umbel diameter of primary umbel (6.17 - 13.67 cm), number of primary umbels plant (1-12), umbels plant (8-40), seed yield per plant (0.55-13.10 g), essential oil content (3.2-9.3 %) etc. Significant and positive association was observed between number of seeds primary umbel (r = 0.91), plant height (r = 0.65), number of seeds primary umbel (0.52), number of seeds primary umbel (0.43), number of seeds secondary umbel (0.38) with number of umblets secondary umbel. Cluster analysis classified the genotypes with different geographical origin into two major clusters and sub-clusters. Cluster-I comprises of 50 genotypes and cluster - II of 24 genotypes while the genotype SRS-KZ-189 from Kargil population was separated as an individual sub-group. Principal component (PC1) and (PC2) harbors accounted 20.2% and 14% of total variation. Variability of Kalazeera genotypes would facilitate the plant breeders to implement and design various crop improvement programme in future.
本研究探讨了不同地区种群的变异性。研究了74个基因型在37个性状（29个数量性状和8个质量性状）上的变异性，以确定该种群的结构。在农艺形态性状中，块茎形状、块茎颜色、种子形状、种子颜色、生长习性、叶形、叶色、伞形、伞色、株高（22.90 - 96.52厘米）、主枝数（1 - 6）、主伞直径（6.17 - 13.67厘米）、主伞数（1 - 12）、伞数（8 - 40）、单株种子产量（0.55 - 13.10克）、精油含量（3.2 - 9.3%）等方面记录到了广泛的变异性。观察到主伞种子数（r = 0.91）、株高（r = 0.65）、主伞种子数（0.52）、主伞种子数（0.43）、次伞种子数（0.38）与次伞小穗数之间存在显著正相关。聚类分析将不同地理来源的基因型分为两个主要聚类和亚聚类。聚类I包含50个基因型，聚类II包含24个基因型，而来自卡吉尔种群的基因型SRS - KZ - 189被分离为一个单独的亚组。主成分（PC1）和（PC2）分别占总变异的20.2%和14%。卡拉泽拉基因型的变异性将有助于植物育种者在未来实施和设计各种作物改良计划。
