An experiment was laid out at farm of Spices Research Sub-Centre (SRSC), Bangladesh Agricultural Research Institute (BARI), Faridpur, Bangladesh during the winter season of 2021-2022. The study comprised 3 new varieties viz. BARI Piaz-4, BARI Piaz-6 and LalTeer King, while BARI Piaz-1 was used in the study as check. The trial was conducted to explore potentialities of new developed varieties for getting higher yield and quality of onion in set to bulb method. The experiment was carried out in randomized complete block design with three replications. The finding depicted that the varieties responded significantly on the parameters studied except days to maturity of bulb and disease rating. The variety BARI Piaz-4 and LalTeer King showed the best performance on the basis of incidence of bolting, split bulb, diameter of bulb, individual bulb weight and yield of onion. On the other hand, BARI Piaz-1 had the highest dry matter content and total soluble solid content against other varieties. Finally, new developed varieties such as BARI Piaz-4 and LalTeer King would be used for getting higher yield of early green onions in set to bulb method.

“…The variation in yield might have due to their differences in bulb weight along with their inherited wealth. The similar result was also provided by Walle et al [7], Dwivedi et al [16] and Lancaster et al (14). Besides, the reason for lower yield from BARI Piaz-1 might be due to producing higher bolting in BARI Piaz-1.…”

“…in different climatic areas. Onion cultivar trials have been performed worldwide because of important information for growers, researchers, seed companies and so on (Azoom et al 2014;Boyhan et al 2005;Cramer 2001; Dangji et al 2018;Lancaster et al 1995;Shock et al 2000;Tesfaendrias et al 2010).

“…1 Maximum, mean and minimum daily air temperatures measured at 10-day intervals during the onion growing seasons resistance, bolt incidence, storability, etc. Bulb maturity, bulb yield and bolting, unlike skin quality and number of centers were significantly affected by seasonal differences which depends on climatic conditions (Lancaster et al 1995). Shock et al (2005) evaluated long-day onions to select cultivars with high percentage of bulbs functionally single-centered for processing uses.…”

We evaluated and classified forty five onion cultivars according to bulb initiation, bulb and scale characteristics, minerals and organic compounds contents, and storage quality in South Korea during 2016/2017 and 2017/2018 growing seasons. Field experiment was conducted in randomized block design with three replications. Bulb initiation ranged from 153 days after transplanting (DAT, April 2) to 177 DAT (April 26). Fresh bulb weight (FBW) and bulb index (BI) were 285.5 ± 18.5 g/ individual, 0.93 ± 0.05, respectively. Number of scales (NS), number of center (NC), and scale thickness (ST) were 7.6 ± 0.2, 2.3 ± 0.2, and 5.5 ± 0.2 mm/scale, respectively. Chroma and Lightness of bulb skin were 27.1 ± 1.9, 61.2 ± 2.3, respectively. Storage loss (SL) on December 12 was 19.4 ± 5.9%. Nitrogen (N), Carbon (C) and sulfur (S) contents were 1.36 ± 0.14, 37.9 ± 3.2 and 0.40 ± 0.06 mg kg −1 on a fresh weight basis. Total soluble solids (TSS) and total phenolics content (TPC) were 8.6 ± 0.6 °Bx, 164.8 ± 15.6 mg GE kg −1 on a fresh weight basis. Days from transplanting to bulb initiation was significantly positively correlated with bulb height, NC, dry matter, N, C, S, TSS, TPC, total flavonoids content (TFC) etc., while it was negatively correlated with rot loss and SL. Dry matter content was significantly positively correlated with N, C, S, TSS, TPC, TFC etc., while it was negatively correlated with SL. Storage loss was negatively correlated with N, S, Potassium and TSS. Dendrogram of agglomerative hierarchical clustering for the forty five cultivars based on bulb initiation, bulb and scale characteristics, and bulb minerals and organic compounds contents classified five cultivar groups. Cluster 1 featured the earliest bulb initiation and the greatest SL. Cluster 2 featured the fewest NS and NR, and the thickest ST. Cluster 3 featured the greatest FBW, and the most NS and NC. Cluster 4 featured the greatest BI and the thinnest ST. Cluster 5 featured the lowest SL, and the highest minerals and antioxidant compounds contents. This information should be helpful for onion growers to decide onion cultivar and for onion breeders to promote new cultivars depending on their purpose.

“…Traditional breeding methods may not be sufficient to allow New Zealand cultivars to adapt quickly to these trends for two reasons : New Zealand cultivars do not contain the characteristics required to develop such onions and cultivars from overseas are not suited to the New Zealand climate (Lancaster et al 1995). In addition to these local breeding problems are the inherent difficulties of onion breeding.…”

This review outlines the potential for developing a reliable transformation system for onions (Allium cepa). A summary of the onion tissue culture literature is presented along with descriptions of the gene transfer systems available. The most suitable regulatory sequences and selective genes that could be used for onion transformation are described, together with the problems which may be encountered following the integration into the particularly large genome of onion. The review proposes likely routes by which transformation and regeneration may be achieved, and suggests possible characteristics of onions which may be altered using such a technique.
