Study of tomato breeding forms based on a complex of biological and economic characteristics

In Dagestan, there are local varieties of tomatoes that have valuable economic and biological characteristics: good yield, excellent taste qualities fruits, high technological qualities, etc. this regard, the Apple variety is interest. However, uneven represents a motley population. There deviations – low-yielding, weak-leaved, strongly exposed to sunburn, with different fruit shapes from rounded flat. Fruit ripening also occurs at times. Some plants bear early, others-late. The research was carried out in order improve by method intra-variety family selection. forms meet set goals highlighted. These include numbers 22.43 56 early–maturing group, mid–late - 1a, 3, 3a, 6a. Early–ripening 22, 43 had an advantage over control yield 4.0 12.4 t/ha, i.e. 7.1 22.1%, commercial fruits 5.9 -14.4t/ha or 11.6 -28.5%, early 1.4 3.7 t/ha. Mid-late 6a, higher 5.0 11.3 t/ha 10 -11.3%, 6.8 -12.8 13.4 25.3% more than control. According harvest, number 6a stood out. Its harvest for first collections obtained above 7.8 t / ha.
