INTRODUCTION
The botanical species of lettuce (Lactuca sativa L.)
belongs to the Asteraceae family. Its species Lactuca
sativa L. is divided into the following subspecies:
Lactuca sativa var. acephala - single leaf varieties;
Lactuca sativa var. capitata - varieties of lettuce with
different appearance (the leaves have an oily layer);
Lactuca sativa var. sapitata - cruciferous leaf, different
types of lettuce (ice salad); Lactuca sativa var. romana
(romaine salad - Roman salad) - head salad, head salad
with oblong-round leaves, half head forms are also
found; Lactuca sativa var. Angustana (asparagus salad)
[1; 2; 3; 4].
Vegetables include a group of green crops, particularly
cultivated lettuce. Green vegetables are crops that are
mainly eaten fresh. Among these lettuces, the main
lettuce is Lactuca sativa var. sapitata is a crop of great
importance in human health and agriculture [5; 6; 7; 8].

In the conditions of the Republic of Uzbekistan, it has
not been long since the cultivation of lettuce began.
Today, the agro-technologies used in the cultivation of
head salad in the republic are not fully scientifically
based, and conducting research in this regard is an
urgent issue and it is desirable to conduct research.
In the world, in recent years, comprehensive measures
and organizational activities have been carried out to
ensure food safety of the population, to fully satisfy
their needs for vegetable products, and to expand the
assortment of vegetable products. As a result, in
recent years, the introduction of non-traditional new
vegetable crops has been achieved, and the
agrotechnologies of their cultivation are being
improved.
RESEARCH RESULTS
Experiments In the conditions of the Republic of
Uzbekistan, the Tashkent experimental site of the
Scientific Research Institute of Vegetables, Pulses and
Potatoes has been conducting research on the
selection of varieties and F1 hybrids of lettuce (Lactuca
sativa var. capitata L.) and improving the elements of
cultivation technology since 2020.
In the experiments, the main lettuce variety
Krupnokochanniy and Barcelona F1, Madrid F1,
included in the State Register of agricultural crops
allowed to be planted on the territory of the Republic
of Uzbekistan, more than 10 samples of varieties
imported from other foreign countries will serve.
Here, varieties and hybrids from Russia (Great Lakes
659, Russkiy bogatyr, Salat iceberg, Ays quin, Russkiy
razmer, Alabama, Kolobok, Patritsiy), Spain (Barcelona
F1, Madrid F1) are being cultivated.
In the course of the study of lettuce variety samples,
their most important morphobiological characteristics
were evaluated and divided into groups, based on the
analysis of the conducted research and the
determination of the preliminary results.
Plant height, leaf length, leaf width, number of leaves,
weight of cabbage were measured.
During 2020-2022, as a result of observations of head
salad in the spring period, the following indicators
were recorded on the head weight and average 3-year
productivity of samples of varieties and hybrids.
In the standard Krupnokochanniy Variety, this figure
was equal to 492,3 grams.
A figure close to them (90,6-103,1%) was observed such
varieties as Kolobok , Alabama . Large cabbage head
weight (115,8
–
116,7%) compared to the standard
Krupnokochanniy variety was observed in the varieties
Patricia , Russky razmer , and the lower pointer to the
standard was in the varieties Gray likes 659 , Russky
Bogatir salad iceberg and Ays Kvin (45,0

In the second standard Barcelona F1 hybrid, the head
weight of cabbage was equal to 615.0 g. Compared to
him, the high pointer Robinson F1, Madrid F1 was
determined in hybrids (118,6
–
119,1%), and the Salad
Exrgess F1 was a low indicator (94,8%) compared to the
standard.
The average yield of varietal specimens by region was
as follows in 2020: the average yield of 9 varieties of
Russia is 18,7 tons per hectare; the average yield of
Barcelona F1, Salad Exrgess F1, Robinson F1, Madrid F1
hybrids amounted to an average of 29,3 tons per
hectare.
As you can see, the yield of hybrids compared to
varieties has become somewhat higher.
The yield of 2021 was 20,4 t/ha in the standard variety
Krupnokochanniy, and the indicator close to it
(among±10%) was observed in the varieties Kolobok,
Alabama.

32,1 t/ha), and the low yield Salad
Exrgess F1 was observed in a hybrid of 25,7 t/ha.
Three years (2020-2022) the average yield was 21,4 t/ha
in the standard variety Krupnokochanniy and the
hybrid standard Barcelona F1 27,0 t/ha. The yield
relative to the standard variety (19,2-20,1 t/ha) was
observed in the Kolobok, Alabama varieties and
thesalad Exrgess F1 hybrid, while the low yield was
observed in varieties (9,7
–
16,7
–
16,5
–
19,2
–
13,4 t/ha) was
observed in the varieties Grayt likes 659, Russky

yields of 116,8
–
118,6 percent compared to the standard
Barcelona F1 hybrid were obtained in the Robinson F1,
Madrid F1 hybrids.
CONCLUSION
According to the analysis and results of the tests
carried out in 2020-2022, the highest result of the head
cabbage weight and yield indicator in the varieties and
hybrids of the head salad was 574,6 grams of weight,
productivity (25,0 tons) in the Russky razmer variety.
Madrid F1 was recorded in 732.3 g, yield (32,0 tons),
hybrid, and the smallest cabbage head weight in
varietal specimens was 221.6 grams at Greyt likes 659,
while the yield was 9,7 tons.
