Abstract:
This scientific article mainly provides information on the study and propagation of potato collection
variety samples, their growth and development, and yield. The research was conducted in the experimental fields
of the Karakalpak Research Institute of Agriculture in 2024. Today, potatoes are planted on more than 21.5 million
hectares in more than 160 countries of the world, and more than 351 million tons of potatoes are harvested
annually.
Keywords
: Potato, collection, variety sample, germination, budding, flowering, number of stems, plant height,
yield.
Introduction:
Today, potatoes are the second largest
agricultural crop in the world after wheat, rice, and
corn in terms of area, and second in importance. That's
why they call potatoes second bread. Potatoes are a
source of proteins, starch, various vitamins, elements,
and mineral salts that are important for humans.
The biochemical composition of potato tubers consists
of 75% water and 25% dry matter. Starch constitutes
70-80% of the dry matter, and its content in the tubers
is 13-20%, protein 2-3%, fiber 1%, oil 0.2-0.3%, sugar
1%, and ash 0.8-1.0%. In addition, potato tubers
contain vitamins (C, B1-B6, PP, K, and carotenoids).
Mineral elements (calcium, iron, iodine, sulfur,
phosphorus, potassium, etc.) in nodules play an
important role in strengthening bones and muscles in
the div of a growing person. Potato protein is rich in
essential amino acids (like lysine, leucine, valine,
tyrosine, isoleucine, methionine, tryptophan) and
surpasses other crop proteins in its biological
significance.
The countries with developed potato cultivation are
Russia (4.4 million ha), China (4 million ha), Poland (2.2
million ha), Germany (0.7 million ha), the USA (0.5
million ha). [4;5].
Potatoes are grown on very large areas in the USA,
Canada, Holland, Finland, Germany, France, Italy,
England, India, Poland, Czechoslovakia, Russia, Belarus,
China, Japan. [5, 6].
METHODS
It was conducted in 2024 in the experimental fields of
the Karakalpak Research Institute of Agriculture. In the
study, 16 potato varieties, included in the state register
created by the Research Institute of Vegetable, Melon
Crops and Potato Growing, were planted in 2 rows at a

RESULTS AND DISCUSSION
Variety samples of early-season potatoes, imported
from the Research Institute of Vegetable, Melon Crops
and Potato Growing and sown for the purpose of
studying and selecting local varieties in the conditions
of the Republic of Karakalpakstan:
SPE AND KITI's
Aqrob, Diyora, Toshkent Yertagisi,
Uzbekistan Qizili, Umid, Pitek, Evolyushen, Kaya, Zerve,
Hamkor-1150, Ultraeshim, Arizona, Quvonch-1656,
Bardoshli-3, Yaroqli-2010. In the experimental field of
local Santa varieties, samples of each variety were
sown according to the 70×25 cm scheme in 5 meters in
2 rows, 1 repetition.
In the experimental variant, 16 varietal samples were
sown. Phenological observations and biometric
measurements were carried out on the potato
collection planted in the selection garden. After sowing
every 10 varieties, the Sante variety was planted as a
control. In the top ten, the varieties Aqrob, Diyora,
Toshkent ertagisi, Uzbekistan qizili, Umid, Pitek,
Evolyushen, Kaya, Zerve, Hamkor-1150 were compared
with the control Santa variety. If the control variety
Sante germinated 10% in 18 days and 75% in 29 days,
then compared to it, the lines Diyora, Uzbekistan qizili,
Umid, Arizona, Evolyushen germinated 10-75% of
seedlings 3-4 days earlier than the control variety. In
the budding and flowering period, Uzbekistan red,
Evolyushen, Khamkor-1150, Ultrayeshim, Quvonch-
1656, Yaroqli-2010 samples were observed 1-7 days
earlier compared to the St. Sante variety.

According to the research results, in the control variety
Sante, it took 18-29 days for 10-75% of potato seedlings
to germinate, while in some potato samples, including
the Diyora, Uzbekistan qizili, Umid, Arizona, and
Evolyushen lines, germination was observed 3-4 days
earlier.
Among the studied potato varieties, the yield of some
varieties was higher than in the control variant. Among
the collection varieties, the yield of the Uzb kizili variety
was higher than the control variant by 3.4 tons or
29.0%, Evolyushen by 21.9 tons, 187.1%, Ultrayeshim
by 15.4 tons, 131.6%, Bardoshli-3 by 29.8 tons, 254.7%.
CONCLUSIONS
Samples of 15 collections from the Research Institute
of Vegetable, Melon Crops and Potatoes were studied.
As a result of the research work, 5 varieties with good
phenological and economically valuable traits, early-
ripening, high-yielding, were selected in the selection
kindergarten and will be used for research in the
following year.
