Initial material for breeding heterotic early ripening tomato hybrids for open ground
The analysis of hybrid combinations created with the aim of obtaining early ripening, productive tomato hybrids for open ground, capable of giving a high yield in a short growing season in the Republic of Dagestan with the least loss in case of late blight disease. Evaluation of the studied hybrid material showed that the parental lines: Otradny, Gift, (Vihren x Yamal), (Topaz x Otradny), (Pamir x Marty), L 43/2 fruits do not crack, are able to set fruits at high temperatures. The hybrid combinations identified by us differed in yield, early maturity, shape, color, fruit weight, plant type, and resistance to late blight. This material will be used in further breeding work to create early maturing and productive hybrids.
