“…Bulb yield reduction might be due to reduction in leaf photosynthesis and the translocation process toward developing bulbs. In agreement with the results of this study, Lee et al [4] reported that the difference in maturity and environmental conditions can affect the bulb yield, rather than the variety. Lee et al [4] evaluated the performance of 55 intermediate-day onion cultivars and clustered the genotypes based on fresh bulb weight, bulb initiation, bulb maturity and marketable bulb In the diagrams, the coordinates of a given variety are the values of the first (V 1 ) and second (V 2 ) canonical variable, respectively.…”

Lee et al [4] evaluated the performance of 55 intermediate-day onion cultivars and clustered the genotypes based on fresh bulb weight, bulb initiation, bulb maturity and marketable bulb yield. Their results classified 55 cultivars into five clusters, with close distances in clusters among late-maturing cultivars.…”

“…Short-day onions initiate bulbs when daylength exceeds 11-12 h, intermediate-day types when day-length exceeds 12-14 h, and long-day types require more than 14 h [3]. Genetic divergence analysis estimates the extent of diversity present among the genotypes and these could help the plant breeder in selecting the diverse parents for purposeful hybridization [4]. During a previous study, the genetic diversity of thirty-eight onion accessions over two years under filed conditions was investigated by multivariate analysis [5].…”

Genetic variability and diversity of genotypes are very important for all living organisms. Knowledge of the genetic diversity is a potential tool for pre-breeding parental selection. The present experiment was conducted at two locations (Isfahan, Khuzestan) under field conditions during the 2017–2018 growing season, with fifteen short day onion genotypes which were evaluated by multivariate methods. Nine quantitative traits were studied. MANOVA showed that the locations, varieties and location×variety interaction were significantly different for all nine traits. Significant positive correlation observed for two locations for yield and single weight (0.85 in Khuzestan and 0.61 in Isfahan), yield and bulb height (0.52 in Khuzestan and 0.55 in Isfahan), bulb height and index shape (0.68 in Khuzestan and 0.70 in Isfahan) and bulb diameter and single weight (0.81 in Khuzestan and 0.66 in Isfahan). Further, yield was significantly correlated with dry matter: positively in Isfahan (0.62), and negatively in Khuzestan (–0.54). In Khuzestan, the first two canonical variants explained 79.19% of the total variation between the varieties; however, the greatest variation was found for the Saba and Behbahan improved population. The first two canonical variables explained 86.76% of the total variation between the varieties in Isfahan. Saba and Behbahan improved population varieties were the smallest, while Paliz and Early Super Select were the largest. The Saba and Behbahan improved population, as the most diverse genotypes, were recommended for further inclusion in future crop improvement programs.

“…Previous studies reported low level of heritability in shape and size in diameter and weight whereas, high heritability in height and shape and showed that bulb shape responds to selection but not size (Nakamura 1959;McCollum 1976;Dowker et al, 1984;Dowker, 2018). High genetic progress was reported for bulb weight (Lee et al, 2020). The shape of the bulb is determined by several genes and heritability values that range from moderate to high (Jones and Mann, 1963;McCollum, 1976).…”

Onion is a long-cultivated vegetable crop that originated in Central Asia. Almost everywhere in the world, onions are cultivated because of their culinary, nutritional, medicinal and health benefits. Using traditional breeding methods, breeders and farmers have been working to enhance onion yield for years. While it is currently difficult to meet growing customer demand and deal with unfavorable climate conditions. Due to its biennial life cycle, cross-pollination and inbreeding depression, it has been challenging to characterize significant traits. Consequently, the recently available onion genome sequence and the use of contemporary molecular breeding techniques will help researchers to overcome those challenges and speed up the development of the onion crop.

“…Onion is one of the oldest and most valuable cultures practiced in the world. Despite the high-cost investment, fund, price fluctuation, and the absence of sustainable income, onion remains the most cultivated culture on the planet [ 1 ]. It has a total cultivated area of 5.15 million hectares and an annual production of 99.5 million tons [ 2 ].…”

Allium cepa L. remains the most cultivated Allium species in Morocco and around the world. With the purpose of making the first biochemical characterization of Moroccan onions, several biochemical components have been measured in eleven onion ecotypes. Onions were collected as seeds from different geographical origins and cultivated in the same environment, to eliminate the influence of the environment on biochemical expression. Moisture, total phenols, flavonoids, antioxidant activity, total and reducing sugars, and sulfur dioxide were the biochemical properties of interest. Except for moisture, the eleven onion ecotypes revealed a highly significant variation in terms of the studied biochemical characters. The total phenol and flavonoid content ranged from 5.94 to 11.22 mg equivalent gallic acid/g dry weight and 0.67 to 1.52 mg equivalent quercetin/g dry weight, respectively. The antioxidant activity of the studied onions showed a strong correlation with the polyphenols ( R 2 = 0.7189 ), especially with the flavonoids ( R 2 = 0.8063 ). The sulfur dioxide content parted from 85.60 to 30.43 ppm when measured using the Monier-Williams distillation method. The current results show that there is no correlation between total sugars and reducing sugars. In conclusion, these findings present a clear biochemical profile of Moroccan onion ecotypes, as well as confirm, for the first time, the presence of a clear variation between the biochemical profiles of Moroccan onion ecotypes, which could be useful for future valorization programs.
