“…Another study reported that the number of leaves required to induce curd initiation was less than nine in tropical cauliflower at temperatures of 18 to 30℃ (Wurr, Fellows, & Fuller, 2004). For the conventional varieties of cauliflower, the optimum temperature for young seedlings is around 25℃ which at later growing stage drops to 20℃ for curd formation (Chatterjee & Mahanta, 2013;Kindo & Singh, 2018). However, if the temperature remains high (higher than required for curd formation), the plant will continue to remain in vegetative phase without forming any curd (Lin et al, 2019).…”

“…Based on temperature requirement, they are classified into early, mid and late season groups. Early varieties of cauliflower require higher temperature (20-25°C) for curd formation, while late varieties require lower temperature of 10-16°C (Chatterjee & Mahanta, 2013). The temperature above 25°C adversely affects the formation of curd that results in poor qualities or defective curds in the late varieties (Aleem et al, 2021;Swiader, Ware, & McCollum, 1992).…”

There is a shortage of cauliflower in the domestic market during monsoon and early autumn seasons in Bhutan due to the absence of suitable cultivars for cultivation in subtropical region during these seasons. This study was conducted to assess the genotypic variability in yield of different cultivars of cauliflower under heat and rain (flood) stresses in the subtropical region. Four F1 hybrid varieties of cauliflower from the Takii Seeds, Japan (KSB-12.179, KSB-12.180, KSB-18.297 and KSB-20.320) and three F1 hybrid varieties from Syngenta Seeds, India (C-6099, CFL-1522 and Monsoon Queen) were evaluated in August 2022 in open field at ARDC Samtenling. The experiment was laid out in a RCDB design with three replications using Snow Mystique as the check variety. The objective of the study was to identify short duration, rain and heat tolerant varieties of cauliflower for cultivation in the monsoon season (July-August) in the subtropical region of Bhutan. In addition, all the cultivars were further assessed in September, and five cultivars that performed well in monsoon planting were evaluated in November 2022 as the second and third staggered planting trials to find out their performance in late monsoon and main seasons (September-November) respectively. The results from three staggered trials showed that Monsoon Queen matured in 53 days after transplanting (DAT), 56 DAT and 35 DAT in the first, second and third staggered planting trials with the mean head of 462 g, 376 g and 211 g respectively. In comparison, the check variety matured in 142 DAT, 114 DAT and 77 DAT in the first, second and third staggered planting trials with the mean head of 658 g, 403 g and 767 g, respectively. Monsoon Queen was the earliest maturing variety with good head weight and curd quality among the eight cauliflower varieties when transplanted in August 2022. However, both the head yield and curd quality of this cultivar declined in later plantings, indicating that this variety is not suitable for main season (autumn) planting. With the identification of Monsoon Queen as the heat and rain tolerant cultivar in this study, cauliflower can now be grown even in the monsoon season in the subtropical region of Bhutan.

“…Cluster V (16.51) showed significant heterogeneity with maximum intra-cluster distance followed by cluster IV (15.42). Clusters II and IX were most divergent as depicted from maximum intercluster distance (39.71), suggesting to involve genotypes from these diverse clusters in hybridization to obtain transgressive segregants [38][39][40][41]. The clusters VII and VIII were found to be the most divergent based on cluster means for majority of the valuable traits (curd and plant parameters) that had direct impact on marketable curd weight [34] and can be successfully applied for the selection and identification of various parents for hybridization [38,39,42].…”

“…The introgression of genes (major/minor) during the isolation of new genotypes alter the performance of different attributes for their adaptability and consumer acceptance. The researchers reported wide diversity in various maturity groups of cauliflower viz., early [ 12 ], mid group [ 13 ], and snowball type [ 14 – 16 ] using morphological descriptors. However, the traits across groups are sensitive to environmental conditions and thereby, these observations do not satisfactorily reproduce degree of variation in the genotypes for use in breeding.…”

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.

“…The correlation of agronomic traits with yield and even the correlation between each other and environmental influences on the expression of various features was significant in choosing a selection strategy (Chatterjee et al, 2018;Roy et al, 2019). Path analysis helps determine which attributes have more potential and are better used as benchmark traits in selection assessments (Amas et al, 2021).…”

The enhancement in cayenne pepper (Capsicum frutescens L.) productivity is intently needed due to the ever-increasing demand, considered a vital vegetable commodity with complete nutrition and high economic value in Indonesia. Conventional plant breeding is one of the strategies to produce superior cultivars with increased yield. Thus, the latest research aimed to identify genetic diversity and gene inheritance patterns for selecting high-yielding F2 populations of cayenne pepper made through double and three-way crosses. The said research employed an augmented design combined with a randomized complete block design as an environmental design. The research factors consisted of non-repeating cayenne pepper (Capsicum frutescens L.) lines with a limited number of seeds originating from 10 parental populations. The resulting 100 and 52 F22 individual populations, obtained from double and three-way crosses, respectively, were evaluated in comparison with four control cultivars, i.e., Bara, Dewata, Ungara, and Katokkon. The non-repeated rows, divided into five blocks, included the control cultivars planted repeatedly in each block. The results indicated that almost all traits have high genetic diversity and heritability and have potential use as selection criteria. The traits plant habitus (0.135), stem diameter (0.202), number of productive branches (0.359), and fruit weight (0.171) have a direct utmost influence on yield compared with other traits; thus, these promising traits can serve as selection criteria along with yield.
