GENETIC ANALYSIS OF FIBER QUALITY TRAITS IN F1 HYBRIDS DERIVED FROM MEXICAN AND US COTTON ACCESSIONS AND LOCAL VARIETIES
Abstract
One of the main tasks in the field of plant breeding in our country is to create new early-maturing varieties and initial forms of cotton that are adapted to the soil and climatic conditions of the Republic and have high fiber quality and yield. Therefore, selecting ecologically and geographically distant accessions—such as those from Mexico and the USA—based on valuable economic traits, and crossing them with local varieties to develop intensive, optimally structured, early-maturing, high-yielding forms with high fiber output and quality that meet international standards is a current and pressing issue. This article explores the fiber length, micronaire value, fiber strength, spinning coefficient (one of the indicators of fiber quality), and dominance (hp) degree in ecologically distant accessions, local varieties, and F1 hybrids, and evaluates whether the fiber quality meets international standards.
