THE PHENOTYPIC CORRELATION OF FIBER LENGTH WITH VALUABLE ECONOMIC SIGNS IN THE FIRST F1, SECOND F2 AND ORDINARY-GENERATION HYBRIDS OF COTTON GENETIC COLLECTING LINE
Abstract: The article examines the problems of changing the hybrids of the genetic lines of the collection of cotton economic signs Ghirsutum LF1 and F2 to the best side during their crossing. Keywords: variational changes, combination, introgressive lines, recombinant.
Cotton-plant is one of the most important agricultural crops for humanity, because the product of cotton - fibers and seeds provides a very large number of secondary products. Increasing the productivity of cabbage is a very complex task and requires a complex approach to solving it. It is well known that the proper selection of the method of coagulation, taking into account the genetic variation of the marks in achieving good success in the selection of plants. The correct choice of the method of chatting is one of the most important features of the type of cotton that is related to the fact that the primary parent forms used by breeders contain high positive signs.
The relevance of the topic. The quality of cotton fiber is characterized by its length, elasticity, thinness (metric number), elasticity, elasticity, and flexibility. Generating varieties of this
kind is fundamental in genetically and selectively. The genetic expression ofthe character correlation is a subtropic effect ofgenes or their agility. The polygens that control the quantitative characteristic may be present in the same group of combinations and in most cases act in opposite grafts. Therefore, selection of only one character may lead to a decline in the characteristic characteristic of the population and, in some cases, to a halt [1; 2].
The analysis of correlation relationships with fibers of fiber length, index and 1000 seed weight in the first F1, second F2 generations (Table-1) shows that interconnectedness of fibers with glucose was different at baseline. Correlation of fiber length with glucose output at line L-620, L-4112 and L-39 was found to be significant (r = 0.33; -0.24 and -0.39 respectively).

The correlation coefficient L-39 showed a negative correlation between the mean (Table 6), and the t-criterion (-) of 1.7 was equal to that of Table (2.11), which indicates that the connection between the fiber length of the fiber length in the line at the 0.95 probability is unscrupulous. However, the
index value (-) at the 0.1-magnitude level is 1.74, there is a weak negative link at the 0.9-point range and the coefficient of determinate (R-square) is 0.152. This means that the length of the fiber length on line L-39 is about 15% depending on the gum index (Table-2).

L-489 X L-608 combination correlation between gall-blad output is equivalent to the first F1, second F2 generations -0.14 and -0.28 (their t-criteria = -0.9; -3.1), the effect of line L-489 on the second F2 generation in the hybrids [3].
The combination of L-489 X L-607 is the first F1, and the second F2 generation is correlated with correlation coefficients of 0.03; -0.16 was appropriate.
The combination of L-608 and L-4112 in the first F1 and second F2 generation hybrids is corrosive, correlation coefficients -0.15; -0.17 was equally good.
The combination of L-608 X L-39 in the first F1 and second F2 generations corresponds to -0.08 and -0.33 (their t-criteria = -0.5; -3.2), the effect of line L-39 on the second F2 generation hybrids, (Table 1).
In the combination of L-608 and L-39, the correlation coefficient in the maternal line was r = -0.14 and in the paternity, r = -0.39. Correlation of these markers in the first pair of F1 generations of this combination is insignificant and the coefficient r is 0.08. Secondary F2 generation hypertension showed moderate negative correlation (r= -0.33). The t-criterion of Student was equal to -3.2, indicating that the interdependence between the fiber length of the line fiber was 0.95 in the range of 0.05 (-) 2.11 and the determinant coefficient (R square) was 0.110 that the length of the fiber length depends on the glucose output of about 11%.
The combination of L-4112 X L-39 in the first F1 and second F2 generations corresponded to 0.06 and -0.36 (their t-criteria = 0.4; -3.6), and the effect of the line L-39 was significantly lower than the second F2 generation hybrids.
The coefficient of correlation coefficient L-39 of this combination is r = -0.39, indicating a moderate negative attitude and its analysis is given above. The correlation of these markers in the first Fx generation hybrids of this combination is insignificant and the coefficient r is 0.06.
Secondary F2 generation hypertension showed moderate negative correlation (r = -0.36). Stuudent's t-criterion (-) was equal to 3.6, indicating that the value of the table (-) at the point of 0.05 (-) greater than 2.00 indicates that the relationship between the fiber length of the line fiber was 0.95 and the coefficient of determining (R-squared) was 0.128 that the length of the fiber structure is about 13% of the gum emission mark. In the combinations with lines L-608, L-620 and L-4112 of the line 607, the correlation coefficient between the fiber length and fiber output of the first F1, second F2 generation hybrids was impractical and ranged from -0.22 to 0.20.
The combination of L-607 and L-39 is the first correlation coefficient of F1, second F2 generation hybrids (-) 0.17; 0.24, their t-criteria (-) 0.4; 2.5 is equally equally valid, and the impact of the L-39 line has been shown to be strong even in the second F2 generation hybrids.
Thus, the analysis of the correlation counts with the glucose output signal indicates that the L-489 linear interconnect line has a positive intermediate level of 0.05, ie the probability of 95%, and L-39 and L-620, 0.1 at a critical level, ie, a median negative response of 90%.
Correlation of fiber length with fibrillation marks in almost all first F1 generation hybrids was unreliably negatively negative or positive. But in the second F2 generation hybrids, this connection was negative and the correlative relationships of the starting line had its effect. Of the 10 combinations studied, four of the second F2 generation hybrids were found to have a moderate correlation. It should be noted that among these four combinations there were lines with significant correlation indicators, and their effect was in the second F2 generation hybrids. For example, F2 L-489 x L-608, F2 L-608 x x L-39, F2 L-4112 x L-39 and F2 L-607 x L-39, the length and output correlation of the fiber length is 0.05, A moderate negative correlation was found to be 95%. The correlational correlation between fiber length and fiber output in all remaining lines and hybrids was negative.
The relationship between fiber length and fiber index marks in normal hybrids.The correlation of the correlation counts with the fiber index index of the fiber length in the first F1, second F2 genera of normal hybrids indicates that (5), the association of the fiber length with the index of fiber was different in the baseline. Correlation of fiber length to fiber index in line L-489, L-620 and L-39 was found to be moderate (r = 0.56; 0.35 and -0.36 respectively).
Similar to the interdependence between signs of femur length and fiber output, the correlation between the fiber length and the fiber index in almost all first F1 generation hybrids was unreliably negatively negative or positive. But in the second F2 generation hybrids, this connection was negative and the correlative relationships of the starting line had its effect. Although three of the 10 combinations studied were reliable in the second F2 generation hybrids, significant correlation was also observed (Table 1). For example, the correlation coefficients in the second hybrid hybrids F2 L-489 x x L-607, F2 L-4112 x L-39 and F2 L-607 x L-620 (-) 0.23; (-) 0.22 and (-) 0.30, their t-criteria are (-) 2.5; (-) 2.1va (-) 2.5 is equivalent.
The link between the length of the fiber and the weights of 1,000 pounds in normal hybrids.The analysis of correlational correlation indicators with the index of fiber size 1000 pounds in the first F1, second F2 generic normal hybrids shows that (5 tables), the interconnection of the fiber length signage to 1000 pounds of seeds varied in the baseline. The correlation between fiber lines in the line L-489 and L-608 at the line 6 of the parent 6 lines was reliably moderate (r = 0.58 and 0.32, corresponding to T-criteria 2.1 and 2.3).
In the first F1, second F2 generations of normal hybrids, the correlation relation with the value of the fiber length of 1,000 pounds was extremely weak. This correlation was fairly moderate (r = -0.37 and 0.37, according to T-criteria 2.3 and 3.6) in hybrids of F1 L-489 x L-607 and F2 L-608 x L-39 exceptional.
The combination of L-15 and L-607 showed that the correlation coefficients between fiber length and fiber index in parent, first F1, second F2 generation hybrids were negligible and ranged from 0.03 to 0.13.
L-489 and L-15 combination correlation coefficients between fiber length and fiber index in the first F1, second F2 generation hybrids 0.04; 0.01 is in good condition. In the L-489 line only, this correlation is 0.56 and its t-clause is 2.0 and the coefficient of determination (R-square) is 0.314, which means that the length of the fiber is about 31% of the fiber index.
Thus, the third group - the analysis of correlation relations with normal fertility, index fertility and index of 1.000 seeds in normal parents, first F1, second F2 generations, shows that correlation with fibers with glucose and index indices is almost equal to all first F1 in the hybrids ofthe generation unreliable or negative or positive. However, these dependencies were negative in the second F2 generation hybrids and in some combinations there was a relatively moderate correlation. It is possible to assume that the correlation of the starting line has been influenced by this.
The coagulation of the length of the fibers with a sign of 1000 pounds of cotton is characterized by the fact that the correlation of the fiber length to the fiber and the index indices was very low and insignificant compared to the 1000 pound weight. This phenomenon can be explained by negative or negative correlation, known to the marker of the gum output, of 1.000 pounds ofweight.
