ЎРТА ТОЛАЛИ “ПОРЛОҚ-4” ҒЎЗА НАВИНИНГ МОРФО-ХЎЖАЛИК белгилари ВА ТОЛАСИНИНГ СИФАТ КЎРСАТКИЧЛАРИ

It is known that the reflectance coefficient and the degree of yellowness of cotton fiber are important in determining the quality of fiber and its value as fiber length, strength, and micronaire. The higher the light reflection coefficient and the lower the yellowing degree, considered the better cotton fiber. Therefore, scientists pay special attention to the whiteness of the fiber when selecting genotypes with high fiber quality. Results showed that the degree of reflectance coefficient (Rd) and the degree of yellowness in the cotton fiber of the «Porloq-4» variety were higher 0.1 and 1.0% than in the control variety, respectively.All fiber quality traits were higher in the cotton variety «Porloq-4» than the control genotype.
