ABSTRACT 

In the article presents results of analysis of inheritance and variability of some agronomic valuable traits in hybrids 

obtained with participation of cotton varieties that differ sharply in origin. Studied plants Ғ1, it was found that 

complete dominance of unlimited type of branching in Ғ1, effect of heterosis, complete dominance and intermediate 

inheritance depending on the genotype of the parental forms according to traits of precocity and weight of 1000 

seeds. In the inheritance of fiber length in F2 hybrids, a wide range of variability was revealed and a markedly high 

variability in interspecific hybrids compared to simple hybrids. From F3Sultan x Surkhan-14 combination were selected 

and recommended families for breeding.

In the development of the country’s cotton growing, 

much attention is paid to the creation of early, 

productive, resistant to diseases and pests of cotton 

varieties with high rates of economically valuable traits 

and fiber quality. 

In cotton genetics, each method has its own 

advantages. Positive results can be obtained using 

both the intraspecific hybridization method and the 

use of interspecific hybridization.   

In enriching the genotype of created varieties with 

unique traits, interspecific hybridization involving wild 

and ruderal forms is one of the main methods of 

modern genetics and breeding [2,3].  

Each type of cotton has its own unique characteristics 

and properties. The effective use of these species 

makes it possible to combine unique traits in one 

genotype. So, in the studies of D.A. Musaev [5], M.F. 

Abzalov [1], the patterns of inheritance of economically 

valuable traits of cotton were studied and polygenic 

control of quantitative traits was established, and the 

possibility of combining positive traits in one genotype 

and the selection of forms with a combination of these 

features.  

RESEARCH METHODS 

The studies used methods of intraspecific and 

interspecific hybridization. Using these methods, 

hybrids were obtained with the participation of 

varieties of different origin and with a sharp difference 

from each other. The experiment, phenological 

observations and laboratory analysis were carried out 

according to the generally accepted methodology. 

Mathematical analysis of the obtained results was 

carried out according to B.A. Dospekhov [4]. 

Conditionally designated form K-28 isolated from a 

complex hybrid Ғ1(Ғ1G.thurberii Tod. х G.raimondii

RESEARCH RESULTS 

As you know, the productivity of a plant is a complex 

trait, consisting of a number of its constituent 

elements. The main elements of cotton productivity 

are such characteristics as the number of bolls per 

plant, the weight of raw cotton per bolus and the 

weight of 1000 seeds. Many scientists have studied 

inheritance, variability and the formation of these 

traits, in particular D.A. Musaev, (1979), M.F. Abzalov, 

(1991), S. Boboev (2017).  

In our studies, we studied the inheritance of the weight 

of raw cotton in one box and the weight of 1000 seeds 

in F1 hybrid combinations obtained with the 

participation of varieties and accessions with different 

genetic backgrounds.  

In terms of the weight of raw cotton in one box, the 

parental indicators were more than 6 g, families O-107-

12 (7.0 g), O-160-71 (6.8 g) and varieties “Baraka-79” 

had especially high rates. (6.6 g) and SP-1303 

(compressed form, 6.6 g). Only the L-282-85 line had a 

slightly lower indicator (5.0 g.). 

In F1 hybrids obtained with their participation, 

dominance and intermediate inheritance were noted. 

In the hybrid combinations F1 O-160-71 x Baraka-79 and 

F1 L-282-85 x L-1380, the average value of the trait was 

in the range of indicators of parental forms, i.e. 

intermediate inheritance is established. Average 

indicators of hybrids F1 SP-1303 x L-282-85 (6.8 g), F1 O-

107-12 x L-282-85 (7.3 g) and F1 O-87-91 x “Sakhovat” 

(7.4 g) were much higher than those of the parental 

forms, which indicates the manifestation of the effect 

of heterosis (hp=1.6; 1.3; 7.0, respectively) (Table 1).

Among the parental forms, the SP-1303 variety 

(compressed form) of 140 g had the highest average 

weight of 1000 seeds, and the L-282-85 line (118 g) had 

the lowest. Also high results were shown by families O-

107-12 (136 years old) and O-87-91 (134 years old).

combinations F1 O-107-12 x L-282-85 and F1 SP-1303 

(form 2) x “Baraka-79”, the dominance of the parental 

form with a high indicator of the trait was revealed, and 

positive heterosis was noted in the remaining 4 hybrid 

combinations. Hybrid combinations F1 L-282-85 x L-

1380 (hp=2.0) and F1 O-87-91 x “Sakhovat” (hp=5.0) 

exceeded the parental forms by 6-18 g. 

In general, F1 hybrid combinations according to the 

characteristics of the weight of raw cotton in one box 

and the weight of 1000 seeds have established 

intermediate inheritance, complete dominance and 

heterosis, depending on the genotype of the parental 

forms. The established patterns in the inheritance of 

these traits show the possibility of isolating 

recombinants that combine large boxes and a high 

mass of 1000 seeds. 

Fiber length. The length of the fiber is one of the most 

important features that determine the quality of the 

fiber. We studied the inheritance of this trait in 

intraspecific and interspecific hybrids F2 and F3 with 

the participation of species forms G.hirsutum L. and  

G.barbadense L. 

Among the parental forms, the variety “Surkhan-14” 

(37.8 mm) had the highest indicator of fiber length, and 

the lowest was the variety “Sultan” (34.0 mm). The 

fiber length of other parental forms was in the range of 

34.1-35.2 mm. The average fiber length in the 

intraspecific hybrid F2 “Jarkurgan” x “Omad” ranged 

from 34.5 mm, and in F2 “Sultan” x SP-1303 34.8 mm. 

Indicators of the coefficient of variability were V=7.34% 

and V=8.61%, respectively.  

The interspecific hybrid F2 “Sultan” x “Surkhan-14” had 

an average fiber length of 36.2 mm. It was noted that 

the location of plants in the middle and right classes of 

the variation series was influenced by the genotype of 

the paternal variety “Surkhan-14”. Plants with a fiber 

length of 39-41 mm were split off. In combinations F2 

(F1K-28) x C-4727 and F2 (F1K-28 type arbor.) x Omad, 

the average fiber lengths were 34.5; 34.6 mm 

respectively, i.e. were in the range of parental forms. 

Despite this, left-and right-sided transgressions were 

revealed in interspecific hybrids. The degree of 

variability of interspecific hybrids was V=10.18%, 

V=12.05% and V=13.6%, respectively, and was 

significantly higher than that of intraspecific hybrids. 

The fiber lengths of the intraspecific F3 hybrids were 

almost the same, i.e., 34.6; 34.7 mm. The plants of both 

hybrid combinations were located in 6 classes of the 

variation range, from 31.1-32.0 mm to 36.1-37.0 mm, the 

degree of variability was V=5.21 and V=5.89%, 

respectively (Table 2).

and 34.1 mm, respectively. 

CONCLUSION 

The results obtained make it possible to conclude that 

the genotypes of parental forms involved in 

intraspecific and interspecific crossings significantly 

affect the inheritance and variability of the fiber length 

trait. From the interspecific hybrid combination F3 

“Sultan” x “Surkhan-14” unique families with a fiber 

length close to the species G. barbadense L were 

isolated and recommended for breeding.
