“…sub-cluster-IIa) and few nodes in sub-cluster IVa had genotypes particular to maturity group such as sub-cluster IIa (KT-17, KT-13-01, KT-25 and KT-22 of late group) and three nodes of sub-cluster IVa (one, DC-321, DC-310, DC-385, DC-309; two: DC-402, CCM � HR and DC-3023-2; three: DC-522, DC -383, DC-325 and DC-308), (iii) in one subcluster, the genotypes of mid-late and late group were placed together, and (iv) the genotypes of broccoli and cabbage were grouped alongwith cauliflower and they could not make separate clusters. Similar results were earlier reported by Vanlalneihi et al [44] while studying genetic diversity using 26 SSR markers in 48 genotypes of three maturity groups of Indian cauliflower. The SSR markers could corroborate the agro-morphological grouping to some extent with PLOS ONE respect to Indian and Snowball cauliflower only.…”

“…The SSR markers have been well employed in understanding the genetic variations Brassica species for diversity studies [20,23,41,42]. Earlier, RAPD, ISSR and SSR markers have been used for linkage analysis in cauliflower for characterization of self-incompatible lines [43], genetic diversity analysis [44] and linkage analysis with downy mildew [45,46] and black rot [47]. The SSRs with high polymorphism are useful for parent selection, mapping of specific traits and their introgression.…”

The present study analysed the molecular and agro-morphological diversity in a set of 92 diverse cauliflower genotypes and two each of cabbage and broccoli. Field evaluation of the genotypes was done in randomized block design (RBD) at two locations (i.e. IARI, New Delhi and ICAR-RC-NEH Region, Barapani) during Rabi2019-20. Genotypes showed variation for all the eight observed traits at both locations and, the differences in early and snowball groups were distinct. Pusa Meghna, DC-33-8, Pusa Kartiki and CC-14 were earliest for curd initiation. Genotypes showed higher values for curd traits at Delhi. Molecular diversity was detected with 90 polymorphic simple sequence repeats (SSR). Number of alleles ranged from 1 to 9 with mean value of 2.16 and the highest polymorphic information content (PIC) value was observed for primer BoGMS0742 (0.68) with a mean value of 0.18. Cluster analysis using agro-morphological traits substantiated classification of the genotypes for maturity groups. However, SSR analysis revealed four clusters and with a composite pattern of genotype distribution. STRUCTURE analysis also supported the admixture and four subpopulations. The studyindicates for introgression of genetic fragments across the maturity groups, thereby, potential for use in further genetic improvement and heterosis breeding.

“…In sub-cluster (A 2 ), genotypes of mid-late group (e.g., DPCaY-7 and DPCAY-9) were placed together while certain sub- clusters had genotypes particular to late maturity group as depicted in sub-cluster B 2 (Pusa Snowball K-1 and Pusa Snowball K-25) . Vanlalneihi et al [ 49 ] and Rakshita et al [ 46 ] also observed agro-morphological and molecular diversity in diverse set of genotypes from different maturity groups of Indian cauliflower. Cauliflower genotypes have vast ecological distribution, strong environmental adaption, capacity to survive, and evolutionary consequences all contribute to its expanded genetic diversity [ 50 ] on account of its sensitivity to temperature for curding and thereby, distribution of genotypes to different maturity groups.…”

Genetic diversity is the prerequisite for the success of crop improvement programmes. Keeping in view, the current investigation was undertaken to assess the agro-morphological and molecular diversity involving 36 diverse mid-late and late cauliflower genotypes following α-RBD design during winter season 2021–22. Six morphological descriptors predicted as polymorphic using Shannon diversity index with maximum for leaf margin (0.94). The genotypes grouped into nine clusters based on D2 analysis with four as monogenotypic and gross plant weight (32.38%) revealed maximum contribution towards the genetic diversity. Molecular diversity analysis revealed 2–7 alleles among 36 polymorphic simple sequence repeats (SSR) with average of 4.22. Primer BoESSR492 (0.77) showed maximum polymorphic information content (PIC) with mean of 0.58. SSR analysis revealed two clusters each with two subclusters with a composite pattern of genotype distribution. STRUCTURE analysis showed homogenous mixture with least amount of gene pool introgression within the genotypes. Thus, based on morphological and molecular studies, the diverse genotypes namely, DPCaCMS-1, DPCaf-W4, DPCaf-US, DPCaf-W131W, DPCaf-S121, DPCaf-18, DPCaf-13, DPCaf-29 and DPCaf-CMS5 can be utilized in hybridization to isolate potential transgressive segregants to broaden the genetic base of cauliflower or involve them to exploit heterosis.
