Today the market of onion is presented with a large assortment of new quickly ripening varieties and hybrids F1. We carried out a test with the purpose to learn and estimate the new quickly ripening sorts of onion that most coveted by vegetable growers. The tests were carried out at the plot of variety study that is located at the breeding center "Gavrish" in the Krymsk district of Krasnodar Region in 2014-2015. The test was made in two replications. The spacing of plot registration is 10 m2. As the study subject were chosen the early ripening onion varieties (vegetation period is 100-105 days from sprouting till leaves lodgings). As a standard the early ripening hybrid F1 Centavr (breeding center "Gavrish"), Russia, was used. It is established that the most attractive appearance has the onion with brown color of dry glumes the Hybrids F1 Spanish medallion and F1 Centurion are marked by this index. For the mechanized cultivation we can use samples F1 Takmark having strong engagement and the the thick dry glumes and also samples of F1 Takstar, F1 Comandora and F1 Bonus with strong engagement and the glumes with middle thickness. Using such mark as weight we can separate out one sample of F1 Takmark that has the low the variability index, in other words the high uniformity (X=115,3�5,3 and CV =20,6%). As about crop yield the leaders are F1 Buffalo and F1 Camaro, their crop yield is 8,0 kg/m2 and 7,9 kg/m2. F1 Music is sweet, the general content of sugar is 6,2 %. Hybrids F1 Isi 30230 (11%), F1 Takstar (10,9%), F1 Takmark (10,5%), CRX 2313 (10%) have sharp flavor. High degree of safety have hybrids of F1 Takstar, F1 Bonus, F1 Takmark, F1 CRX 2313. Hybrid F1 Music also has high degree of safety despite of low content of sugar and thin glumes.
