Abstract
This article analyzes the size of the surface of corn leaves in saline soils of the Syrdarya region and the degree of correlation between the traits associated with it in terms of genotypes. According to the results of the study, the leaf area for per plant was 1633.4 cm2 in Daulet, 1001.0 cm in Line 1 and 1300.3 cm2 in Line 2, while the dry matter content was respectively 32.78, 25.82 and 29.72 g. A strong (r => 0.7) correlation was noted between the fact that the size of the leaf surface depends more on its length and width. The same result was determined by the size of the leaf surface and the amount of dry matter. It has been found that high yields can be obtained from saline soil conditions from low-yielding lines of corn.
Keywords: Corn, Daulet, line, variety, morphology, correlation.
