ABSTRACT
During the years of independence in our republic, based on the creation of a number of new varieties of medium and
fine fibers with a complex of valuable economic characteristics of cotton, concrete results are achieved in the creation
and introduction into production of sustainable medium and fine fiber varieties of cotton, genetically enriched to the
impact of various extreme factors of cotton growing.

INTRODUCTION
In our conditions, early ripening determines the
amount of harvest, the quality of cotton and fiber. In
particular, after flowering, especially during the
flowering period, the growth and development of
cotton accelerates.
According to the literature, the duration of the
growing season in F1 plants crossbred G. barbadense L.
varieties with G. darwini Watt was found to be
inherited
in
dominant,
super-dominant
and
intermediate states [1].
Boboev S.G'., Namazov Sh.E., Kholmurodova G.R., in
their research on improving early ripening in hybrids
involving several wild and cultivated types of cotton,
mentioned that the involvement of early maturing
varieties as fathers gives good results [2].
When studied by G.A.Dusmatova, I.T.Kakhorov, the
level of heredity of the coat hair color indicators of
interspecies (G. hirsutum L. x G. barbadense L.) and
hybrid seeds obtained by cross-breeding is different, in
most cases, reciprocal differentiation was determined,
and the degree of heritability was shown to be related
to the origin and genotype of their parental forms and
the direct interaction of non-allelic genes [3].
In research, when ecologically distant forms of a
species are interbred, their traits are inherited
according to the same law as in ordinary hybridization.
In this case, there is more opportunity to choose, and
the varieties formed in very different conditions are
expected to have some valuable traits (such as disease
resistance, high fiber quality, large pods) that are not
characteristic of local varieties [4].
The Main Findings and Results
According to scientists’ research, the plant height of
the Marvarid cotton variety in the optimal water
regime is 100.7 cm, the number of bolls in one plant is
37.2 pieces, the biological maturity is 124.3 days, the
weight of cotton in one boll is 3.5 g, the September
cotton yield is 59.0 g/plant, the fiber length is 38.5 mm,
1000 the weight of the seed is 115.0 g, and 94.7 cm in
water shortage, respectively; 36.5 units; 121.9 days; 3.2
g.; 60.6 g/plant; It was 37.7 mm and 110.1 g. The fiber of
the variety belongs to the I-type, and its micronaire is
3.8-4.0. The variety is resistant to drought, pests
(spider mite, bollworm, autumn nightworm) and is
distinguished by rapid opening of bolls. In addition to
the southern regions of our republic, it is also
recommended for planting in regions with a water
shortage and a temperate climate [5].
Kadyrov Sh.Yu. and others to study the correct
selection of parental pairs when 7 varieties (Niyat,
Hurma, Rakhmad, Darkham, AN-519, Davr, Khorezm-
127) and 2 ridges (L-86, L-14) were crossed with
incomplete diallel , it was observed that plants with
high ripening speed, pod opening speed and high
productivity were obtained from hybrid populations
[6].
A.A. Mamaroziev and others show that early ripening
and fiber yielding traits of cotton are inherited in
dominant and intermediate cases [7], Rafieva F.U. and
Rizaeva S.M. when they analyzed the inheritance of the
sign of requirement for day length in interspecies G.
mustelinum x “Beshkhahramon” hybrid combinations,
F1 hybrids showed a wide range of variation in
flowering, flowering and fruiting under long day
conditions, and in F2 hybrids under long day conditions
[8].
Scientists have identified 10 promising G.barbadense L.
species CCB-5, CCB-11, CCB-17, CCB-26, CCB-27, CCB-28,
CCB-29, CCB-30, CCB-33 and CCB-36 those who
evaluated their genotypes positively according to
speed. Among them, 3 genotypes CCB-5, CCB-29 and
CCB-36 were found to ripen faster in terms of the lower
location of the first crop branch, the shorter period
until the first flower and the first bud opening [9].

and in hybrids, it was inherited in a state of negative
extreme dominance.
CONCLUSION
In short, it has been established that the inheritance of
the time from sowing to flowering occurs in cases of
negative extreme dominance and negative incomplete
dominance, and the first flower opens in shorter
periods in hybrids compared to parental forms. In
particular, the flowers of interspecific hybrids Iolatan-
14 x UzFA-703 and Iolatan-14 x L-20 (67.4 days) opened
the earliest. The flowering period of UzFA-703 variety
was the longest, i.e. 75.4 days on average, when this
variety was taken as a maternal form in interspecies
hybrids, and in stand hybrids, the flowering period was
longer.
