Abstract: In the development of early-maturing, high fiber-yielding, long-fiber, high-yield, and disease- and pest-
resistant cotton varieties, as well as in the identification of hybrids, it is essential to focus on studying their 
morphobiological and agronomic characteristics. In this regard, the effective use of hybridization methods in 
research is required.  

 

Keywords: Cotton, early-maturing, variety, hybrid, morphological, cotton weight per boll, weight of 1000 seeds. 

 
Introduction: After the independence of our country, 

significant attention has been given to the selection of 

agricultural crops. 

Currently, all focus is directed toward the creation of 

early-maturing, high-yielding, high-quality fiber, 

disease- and pest-resistant cotton varieties. As a result, 

while maintaining high productivity, the areas allocated 

for cotton cultivation have been reduced, and plans are 

in place to plant other crops. 

In cotton genetics and breeding, it is crucial to utilize 

forms that differ from each other based on their origin, 

productivity, and other valuable agronomic traits. This 

approach has been confirmed in the scientific research 

of many scholars. 

S. Mirakhmedov identified that the resistance of wild 

Mexican cotton to verticillium wilt is inherited in its 

hybrid offspring. As a result of his research, early-

maturing cotton varieties with high yield and fiber 

quality, as well as resistance to wilt, were developed. 

When creating Tashkent varieties, the Mexicanum 

subspecies, which had brown-colored fibers, was used 

for hybridization. In the offspring of these hybrids, 

biotypes with white fibers were identified. It was also 

established that the Mexicanum subspecies of cotton is 

not only resistant to wilt, but also has high yield, 

drought resistance, high fiber output, and fiber quality 

[7]. 

The analysis showed that in the C-6524 variety of 

cotton, 57-89% of the weight of cotton per boll is 

determined by genes, and 11-43% is influenced by

external factors [6]. 

In the experiment, by using topcross hybridization, the 

inheritance of major agronomic traits in F1 hybrids 

from both the parental lines and varieties, as well as the 

general and specific combining abilities of the parental 

lines, were observed to differ from each other. 

The analysis of the dispersion of the inheritance of 

valuable traits, such as the number of bolls, the period 

from germination to maturity, the cotton weight per 

boll, fiber yield, fiber length, and plant height in the F1 

hybrids, was conducted. The results of this analysis 

were clearly identified [1]. 

According to the analysis of the results, in the second 

generation, many agronomic traits deviated from the 

indicators of the parent forms, thus expanding the 

selection potential [2]. 

In research conducted by Akhmedov J.Kh. and 

Mirzarasulov M., it was found that in the F2 hybrid 

population, cotton yield was associated with boll 

weight, number of bolls per plant, fiber yield, and fiber 

length. It was determined that the yield was related to 

the number of bolls per plant and boll weight. This 

finding emphasizes the need to intensify breeding 

research aimed at creating varieties with high boll 

aggregation and large boll size. However, since the 

correlation between yield and fiber output and length 

was low, it was demonstrated that these traits 

inherited independently in the F2 hybrids [3]. 

At the same time, it was established that fine-fibered 

cotton is slower to mature, yields less, has rounder 

bolls, and is more demanding in terms of temperature, 

irrigation, and fertilization requirements compared to 

medium-fibered cotton. Furthermore, it was found to 

be more resistant to biological stresses, including 

verticillium wilt, aphids, and thrips [3].In the research 

by M.D. Nosirova, it was found that in fields where 

mung beans were cultivated, cotton yield, along with 

fiber yield, increased by 0.7–1.0%, and fiber length 

increased by 0.6–1.6 mm compared to the control 

variety. 

After mung bean cultivation, cotton planting led to a 

reduction in the incidence of wilt, and improvements 

were observed in the technological quality indicators of 

the fiber [4]. 

CONCLUSION 

In summary of the literature review, it can be stated 

that the new cotton varieties being developed today 

are not only high-yielding, early-maturing, and 

resistant to diseases, pests, and adverse environmental 

factors, but also exhibit high fiber yield. Furthermore, 

the fiber quality, including micronaire value, must meet 

the requirements of the textile industry.
