India is second largest producer of onion in the world after China. Onion (Allium cepa L.) is commercially cultivated and widely consumed as vegetable and as spices in India. About 73.23 million tons of onions are produced in the world from 3.65 million ha area. India, being major onion-producing country, produces 20.13 million tons from 1.19 million ha, with a very low productivity of 16.24 t/ha in comparison to Republic of Korea (64.58 t/ha), USA (54.47 t/ha), Spain (53.69 t/ha), Netherland (45.80 t/ha), Japan (42.46 t/ha), Germany (41.86 t/ha) and United Kingdom (41.15 t/ha). Lack of recommended or released variety of high yielding as well as good keeping quality in the country, it creates price fluctuation during off season arrival period. To meet out the domestic requirement and also to fulfill the export demand, selection of high yielding genotype under different agro-climatic conditions is necessary. The experiment was conducted at Nashik and Karnal during Rabi 2017-18. The trial conducted at Nashik, revealed that the highest gross yield (382.13 q/ha) and marketable yield (250.47 q/ha) were recorded in advance line-874 which was at par with line-827 in respect of marketable yield. Highest TSS (13.05%) and dry matter content (14.44%) were noted in line-830 and found at par with lines-562, 799, 823, 832, 865, 886 and Agrifound White, however at Karnal, the highest gross yield (290.28 q/ha) and marketable yield (258.82 q/ha) were recorded in lines-810 and 562, respectively, which were par with advance line-562 in respect of gross yield. The highest total soluble solids (14.40 %) were recorded in advance line-810. It is concluded that the above genotypes can be utilized for white onion breeding programme for develop a good quality variety for different agroclimatic condition.
