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.
