“…However, analysis of seasonal and yearly variations might be useful for gathering information for stable production. The wide variability in both qualitative and quantitative traits found in this study might be useful for identifying genotypes and might be required for the genetic improvement of crops [23,42]. The genetic analyses showed that the differential expression of a number of genes located in chromosomes 1, 2, and 7 are responsible for the differences in root characteristics of carrots [43,44].…”

“…Both qualitative and quantitative morphological characteristics are useful for germplasm studies. Generally, qualitative parameters are useful for varietal identification, while quantitative parameters are required for the development of new varieties [23]. Although there are some reports about the morphological traits of carrots, they are limited to a few germplasms [24,25].…”

Carrot (Daucus carota), one of the most economically important root vegetables, shows a wide range of morphological and biochemical diversity. However, there is a lack of simultaneous systematic study regarding the biochemical composition and morphological characteristics in carrot genetic resources, which is crucial for crop improvement. For this reason, the morphological characteristics, carotenoids, and free sugar content of 180 carrot genetic resources grown in open field conditions from March to June 2020 were accessed to select the lines for a potential breeding program. Altogether, 15 qualitative and 4 quantitative agronomical characteristics were evaluated and grouped into four categories based on root color (orange, yellow, white, and purple). Three carotenoids (lutein, α-carotene, and β-carotene) and three free sugars (fructose, glucose, and sucrose) were also analyzed. The results revealed wide genetic variation in both qualitative and quantitative traits. Most of the genetic resources were orange (n = 142), followed by white (n = 16), yellow (n = 14), and purple (n = 8). Carotenoid profile and content were highly dependent on root color and showed wide genetic variability, while sugar content and profile were independent of the root color. Alpha- and β- carotene were the major carotenoids in orange carrots representing 43.3 and 41.0% of total carotenoids. In contrast, lutein was most dominant in other colored carrots (79.7–98.6% of total carotenoids). In most of the genetic resources, sucrose was the most dominant free sugar, followed by glucose and fructose. The results of this study showed that some genetic resources elevated carotenoid and sugar content. The morphological and biochemical diversity observed in this study might be useful for improving the agronomic traits and biochemical content of carrot lines for breeding programs.

Parsnip (Pastinaca sativa L.) is an edible root that has long been used in cooking and preparing baby food and livestock. The present study was performed to evaluate the phenotypic diversity of 69 accessions of this species to select superiors in terms of root quality in Paykan village, Isfahan province, Iran, in the year 2022. There were significant differences among the accessions investigated (ANOVA, p < .01). Coefficient of variation (CV) was more than 20.00% in the majority of measured characters (64 out of 66 characters), indicating high diversity among the accessions. Foliage width (crown) ranged from 10 to 55 cm with an average of 32.32 cm. Root shape was tapering (33), obtriangular (10), narrow oblong (5), wide oblong (5), obovate (13), and fusiform (3). Root length ranged from 81.2 to 294 mm with an average of 166.44 mm. Root diameter at its middle point ranged from 15.58 to 125.12 mm with an average of 51.83 mm. Root weight ranged from 15 to 1200 g with an average of 315.36 g. Inner core (xylem) pigmentation/color was cream yellow (11 accessions), light yellow (12), yellow (42), dark yellow (2), and yellow–light orange (2). In the cluster analysis based on Ward's method, the accessions were divided into two main clusters according to morphological traits. This is despite the fact that parsnip is part of the medicinal plant native and valuable in most farms in tropical cities. Compared with carrots, parsnip plants are more adaptable to different environmental conditions. The accessions studied here showed high phenotypic diversity. Based on ideal values of the important and commercial characters of parsnip, such as root length, root weight, inner core (xylem) pigmentation/color, root shape, flesh color intensity, flesh palatability, and total soluble solids, 14 genotypes, including Parsnip‐3, Parsnip‐9, Parsnip‐24, Parsnip‐32, Parsnip‐32, Parsnip‐48, Parsnip‐51, Parsnip‐52, Parsnip‐58, Parsnip‐60, Parsnip‐62, Parsnip‐65, Parsnip‐67, and Parsnip‐69, were promising and are recommended for cultivation.

“…Morphological characterization based on qualitative traits of crops is a very crucial and essential first step in any crop improvement and breeding programme [14], [15]. The immense phenotypic diversity has helped to develop a high yielding variety and morphological or phenotypic characterization is considered as the important step in the description and classification of germplasm [16], [17]. Meanwhile, studies on morphological characterization of the collected genotypes have been widely used for the assessment of genetic diversity, breeding value and yield potential of the crop [18]- [21].…”

Sweet pepper is one of the most important nutritious vegetable and its demand is increasing day by day in Bangladesh indicating need to characterize and assess morphological variability for varietal improvement programme. Twenty-one sweet pepper genotypes from native and alien sources were characterized for twenty-six morphological traits using vegetative and reproductive appearances at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh from October 2018 to March 2019. Marked variation was exhibited among twenty-six qualitative traits (26) studied. Twenty-two (22) characters showed undeniable variation among the genotypes. The presence of higher percentage (61.90%) of light purple color at node were observed indicated high amount of anthocyanin content. Leaf shape is used as genotypes identifier at vegetative stage and herein three types of leaves were found with dark green color (76.19%) that is highly correlates with yield. In case of flower, same level of stigma exertion (61.90%) with 100% white color corolla indicates higher number of fruit sett were exhibited. Entire genotypes exerted one or more exclusive characters especially fruit shape and color in Bangladesh perspective which could be used as an important breeding tools. Fruit color was observed in various categories at intermediate and mature stage as for instance yellow, green, purple, orange, red etc. in addition higher percentage of blocky fruit shape (38.09%) were observed and these are the consumer fascinating attributes of sweet pepper. However, selection of genotypes with desirable morphological trait can be used for their exploitation of future breeding programme.
