This article presents the results of studies on the analysis of the stability of morpho-biological and physiological indicators of phenotypes under water stress during the growing season of a population of recombinant inbred lines (RIL), obtained by crossing hybrids of cotton varieties Namangan-77, which belongs to the medium fiber types of the cotton (Gossypium hirsutum L.) and the Zangi-Ota, which also belongs to the G.hirsutum L. type bat is sufficiently resistant to water deficiency compared to the Namangan-77 variety. To determine the stability, artificial irrigation regimes of two types were created - conditionally called optimal and dry background, and in these two different background regimes cotton plants of the RIL population were grown. A comparative analysis of the data of two background groups was carried out by comparing the values of the indicators of the phenotypes of the growing season of these groups using the software procedures of parametric and non-parametric mathematical statistics, such as exploratory analysis, Student's t-test for independent two groups and the Mann-Whitney Utest of the SPSS 21 statistics package. The results obtained showed the presence of a statistically significant difference between the main indicators of the phenotypes of the studied groups belonging to different background irrigation regimes. |
