Abstract: This article presents mathematical analysis data on the correlations between root weight and several 
characteristics in simple and complex F3 sunflower hybrid families, including single plant productivity, plant 
height, basket diameter, and total leaf area. In this case, the correlation relationships in highly heterozygous 
hybrids changed in a positive direction, and the high indicators of two-three traits were concentrated in one 
genotype.

Introduction: Today, in the selection of agricultural 
crops, hybridization creates the possibility of changing 
heredity and the emergence of plastic genotypes 
adapted to a new environment based on simple and 
complex selection hybridization methods. 
Hybridization and selection are the main factors in 
creating new varieties and largely depend on the 
chosen crossbreeding methods and the genotype of 
the raw materials. In sunflower selection, the need to 
create varieties with stable hereditary traits using new 
breeding methods is increasing. 

In our republic, one of the urgent tasks is the study of 
the interrelationship of hybrid families with other traits 
of economically valuable traits in the creation of 
drought-resistant agricultural crops, in particular, 
sunflower varieties, which require less water and 
eliminate water shortages. 

L.J.Genjeeva [1] and others conducted research in the 
soil and climatic conditions of Karakalpakstan, as a 
result of studying the relationships between some 

valuable traits of third-generation hybrids obtained 
from simple and complex hybridization of sunflowers, 
they showed that a change in one trait leads to a 
correlative change in another trait. 

The product obtained from sunflower seeds is 
considered one of the main vegetable oils used for 
consumption by the world's population. The surface 
yield of sunflower is 23 million/ha, the average yield is 
14-15 c/ha, and the oil content in absolutely dry seeds 
is 55-56%. In advanced farms of some countries, 
sunflower yields reach 40-43 centners per hectare [2]. 

Based on the results of research conducted by several 
scientists on the study of new sunflower lines in the 
conditions of Karakalpakstan, they came to the 
following conclusions: in the conditions of natural 
salinization of Karakalpakstan, the yield of a new high-
yielding seed kernel from station variety trials proves 
its effectiveness in creating genotypes that meet world 
standards for sunflowers with relatively high indicators, 
and the possibility of transferring L-24, L-28, L-43, and

L-63 lines, which showed relatively high indicators 
compared to the standard variety for the main 
economically valuable traits from the studied lines in 
the small variety trial nursery, to the large competitive 
variety trial next year [3]. 

In the natural saline conditions of Karakalpakstan, 
station seed testing yields of new high-yielding kernels 
proved their effectiveness in creating genotypes that 
meet world standards for sunflowers with relatively 
high indicators, and the possibility of transferring the L-
24, L-28, L-43, and L-63 lines, which showed relatively 
high indicators compared to the standard variety in 
terms of key economically valuable traits, to major 
competitive variety testing next year was presented 
[3]. 

MATERIALS AND METHODS OF RESEARCH 

Our research was conducted in field and laboratory 
conditions according to the applied project of the 
Karakalpak Research Institute of Agriculture "Creation 
of new promising early-maturing, high-yielding, high-oil 
varieties of sunflower by simple and complex 
hybridization, adapted to the soil and climatic 
conditions of Karakalpakstan." All field observations 
were carried out according to the "Methods of 
Conducting Field Experiments," and genetic and 
breeding analyses of the obtained data were carried 
out according to Dospekhov's methods. 

ANALYSIS AND RESULTS 

In order to reduce the selection process of agricultural 
crops and obtain new raw materials and varieties with 
high indicators for most traits, it is advisable to fully 

study plant generations and gradually separate traits, 
as well as reduce the number of combinations created 
as a result of various hybridizations. 

In plants, correlative relationships between traits are of 
varying degrees, and from a genetic point of view, this 
is explained by the clustering of genes in one locus or 
the pleiotropic effect of genes. The relationship of 
characteristics is of two types, i.e., smooth-system and 
non-smooth-system. In a smooth correlation, an 
increase or decrease in the indicators of one trait leads 
to an increase or decrease in the indicators of another 
trait. In the first case, positive correlations arise, and in 
the second case, negative ones. When creating lines 
and varieties of sunflowers with positive main 
economically valuable traits, it is important to analyze 
the relationships of traits, that is, how one trait is in a 
strongly positive state and how it is related to other 
traits. 

In our study, a mathematical analysis was conducted to 
examine the correlations between root weight and 
various characteristics such as single plant productivity, 
plant height, head diameter, and total leaf area in 
simple and complex F3 hybrid families of the sunflower. 
Figure 1. 

In the studied 6 F3 simple hybrid families, there was a 
moderate and strong positive correlation between root 
weight and productivity, i.e., the correlation coefficient 
ranged from 0.57 for example, F3 (Sor Gollips x KK-1), 
to 0.69 for F3 (Tel's x KK-1), and in 3 complex hybrid 
families, a strong positive correlation was found from 
0.66 to 0.69. These indicators provide information 
about the aggregation of genes controlling these traits.

Among these traits, the highest positive correlation 
was observed in the families of the simple hybrid F3 
(Tels x KK-1), F3 (S-Alstor x KK-1), and F3 (Jant lower x 
KK-1), and the correlation coefficient was 0.63-0.69. In 
complex hybrids, the highest positive correlations were 
observed in the families F3 [F1 (S-NS-N-2011 x KK-1) x 
F1 (S-Alstor x KK-1) ], which showed 0.69, and F3 [F1 
(Sor Gollips x KK-1) x F1 (Tels x KK-1) ], which showed 
0.68. The root weight was also positively correlated 
with the plant height trait, that is, the correlation 
coefficient was 0.48-0.73 in simple hybrids and 0.62 to 
0.82 in complex hybrids. In sunflowers, root weight 
significantly influences plant growth and development. 
The developed root system of sunflower adsorbs a 
large amount of nutrients and water and directly 
affects the development of the plant. It was established 
that in the F3 simple and complex hybrid families, the 
correlation between root weight and basket diameter 
was moderately positive. In simple hybrids, it ranged 
from 0.36 to 0.52, and in complex hybrids - from 0.43 
to 0.56. It was established that the root weight is 
connected to varying degrees with the mark of the total 
leaf surface area. In simple and complex hybrids, the 
correlation coefficient was 0.4-0.5. In some hybrids, for 
example, in simple combinations F3 (S-Alstor x KK-1) 
and complex combinations F3[F1 (Sor Gollips x KK-1) x 
(F1 (Tels x KK-1) ], the correlation coefficient was higher 
than 0.6. 

CONCLUSION 

According to the above analysis, it can be concluded 
that the correlation relationships in highly 
heterozygous hybrids changed in a positive direction, 
and the high indicators of two-three traits were 
concentrated in one genotype. This leads to a 
significant acceleration of the breeding process.
