Abstract. The main goal of the study was to obtain hybrids having a heterositic effect using sterile lines of onions (Allium cepa L.) applicated to conditions of Azerbaijan. We used to study a valuable source material from the collection of the National Gene Bank of Azerbaijan. As a result of the combining ability evaluation of the sterile line and the pollinator, the most promising combinations (Arzamas S-1 × Hachmaz Mest, Luganskiy S-2 × Dusti, Arzamas S-2 × Ordubad-2, Luganskiy S-1 × Kaba, Arzamas S-2 × Sabir) were revealed the greatest heterosis efficiency of yield and shelf life quality were selected. The yield of hybrids obtained with the participation of varieties of Arzamas S-1 and Arzamas S-2 and paternal varieties, compared with the Strigunovsky variety, is 17.0–78.0 % higher on average for all the years of testing. The study of the keeping capacity of F1 hybrids showed that almost all of them have a higher keeping capacity than the original varieties. The keeping capacity of hybrids especially increases, the initial varieties of which do not have long-term storage sustainability. So, bulbs of varieties Dustu, Peshpazak, Sabir, Khachmaz mestniy, Ordubad-1 for 180-200 days of storage remained only 26-29 %. Hybrids, obtained with the participation of these varieties; by the end of the study period, the keeping capacity remained at 49.8-88.7 %, i.e. 1.9-3.1 times better. Many F1 hybrids perform heterosis and early maturation, the combinations Arzamas S-2 × Strigunovsky, Arzamas S-2 × Dusti, Arzamas S-1 × Strigunovsky, Lugansky S-2 × Vostochny, Lugansky S-2 × Dusti, Arzamas S-1 × Khachmaz mestniy, Luganskiy S-1 × Kabo were more early matured than the standard for 14-18 days.

Key words: cytoplasmic male sterility, hybrids, heterosis, yield, sterile line.
