In order to isolate valuable forms for practical use, we studied diploid collection samples species G. herbaceum L. and G. arboreum L. from the germplasm of the Research Institute of Soil Science and Agriculture. As a result of observations , samples with high indicators main household signs in two directions. First, for the textile industry - samples with a length of more than 28.0 mm. O they serve as raw materials for textile industry for elastic yarn. The second one is for other purposes (fiber yield 37.5-43.2% ).
Based on sample 0546, which distinguished himself yours heterogeneous properties Based on traits, the T-1980 line was developed through analytical selection . It has a diploid chromosome set and high levels of agronomic traits. The line is completely resistant to verticillium wilt and sucking pests, is high-yielding, early-maturing, and has a high fiber yield. High fiber hygroscopicity and tolerance to water stress were also determined for this line.
