“…Besides, another gene (AcFT7) was also reported which showed highly conserved region with AcFT6 and yet another (comp106231) with low similarity to MFT protein, but containing a PEBP domain. Rashid et al (2016) did not detect AcFT2 and observed that AcFT3 shared 83% identity with AcFT5 and concluded that FT-like protein 1 and FTlike protein 2 genes, similar to AcFT6 and AcFT5, might have influence on bulb formation. In short day onion, Dalvi et al (2016) reported that AcFT6 expression level was high during bulb initiation stage and suggested that it might be involved in bulb initiation.…”

The present study was carried out with the objective of studying the expression of FLOWERING LOCUS T (FT) genes responsible for bulbing in onion. Six AcFT genes were used for expression studies at prebulbing (45 DAT), bulbing (60 DAT) and post bulbing (75 DAT) stage. Two varieties viz., Brown Spanish (long day) and Pusa Riddhi (short day) were used. It was observed that out of the reported six AcFT primers, four were able to amplify. Two new primers exhibiting amplification of AcFT1 and AcFT6 are reported. In short day onion variety, Pusa Riddhi, expression of five out of six genes studied (AcFT1, AcFT3, AcFT4, AcFT5 and AcFT6) were highest at the bulbing stage (60 DAT) suggesting their role in bulbing. In long day variety, Brown Spanish, expression of all the six genes except AcFT1 was very low at bulbing stage (60 DAT). This signifies that specific photoperiod conditions for gene expression were not achieved under Delhi conditions in long day onion. More studies towards understanding of the genes need to be addressed to understand the basic molecular process of bulbing in short day onion.

“…Temperate onions require long days (LD) for bulbing whereas tropical onions will form bulbs in short days (SD) (Rashid et al, 2016). The life cycle of onion can be divided into three main stages, namely seedling growth and bulb formation in the first year and, following overwintering, flowering in the second year (Brewster, 1990).…”

“…The long-day onion cv. Renate requires at least 14 h of light to initiate bulbing (Rashid et al, 2016), whereas Hojem, a short-day cultivar requires at least 10 h to enable bulbing.…”

“…Onion (Allium cepa L.) belonging to the family Alliaceae, is one of the most important and popular vegetable and spice crops cultivated worldwide (Mishra et al, 2013). It is famous for its characteristics flavour and it is widely used to increase the taste of foods like gravies, soups, stew stuffing, fried fish and meat (Rashid et al, 2016). Onion is consumed as a vegetable and condiment.…”

An experiment was conducted to evaluate the efficacy of micronutrients on performance of Onion cv. Sukhsagar at Nadia, West Bengal during 2017-2018.The experiment was laid out in RBD having four replication with six treatments each having FYM @ 20 t ha -1 , viz. T 1 (RDF + soil application of Zinc Sulphate @ 10.0 kg ha -1 ), T 2 (RDF+ foliar application of Zinc Sulphate @ 0.5% at 30 & 45 days after planting (DAP), T 3 (RDF+ soil application of Borax @ 10.0 kg ha -1 ), T 4 (RDF+ foliar application of Borax @ 0.25% at 30 & 45 DAP), T 5 (RDF+ Foliar application of Micronutrient Mixture i.e. iron-2.5%, boron-0.5%,zinc -3%, copper -1%and manganese-1% @ 0.5% at 30 & 45 DAP) and T 6 (control). Highest plant height (63.72 cm), number of leaves/plant (12.71), polar diameter (58.62 mm), equatorial diameter (46.88 mm), average weight (61.72 g) of bulb, yield ha -1 (266.80 q) and highest % (29.82
