Summary: The general data of the three-year study shows that the varieties of cotton that showed high ACS, when they are re-studied, even with a slightly different composition of pollinators in crossings, basically confirm their potential.
Some fluctuations in the manifestation of ACS over the years of research are noted in the case when linear material is involved in crossing. This apparently is due to the heterogeneity of the linear material.
From the above, it follows that to conduct studies on the study of the combinative ability of cotton varieties, it is better to involve more mature varieties in the cross.
Key words: Cotton variety, combinative ability, viticulture, yield, growth and development, fiber quality.
