INHERITANCE OF MORPHO-ECONOMIC TRAITS AND COMBINING ABILITY ANALYSIS IN INTRASPECIFIC HYBRIDS OF GOSSYPIUM BARBADENSE L.

In intraspecific F1 diallel hybrids of Gossypium barbadense L., the inheritance study traits plant height, boll weight, productivity, and 1000-seed with combining ability analysis took place in 2020–2022 at Institute Genetics Plant Experimental Biology, Academy Sciences, Uzbekistan. These polygenic traits’ showed different ways fine-fiber cotton hybrids. The height trait’s overdominance intermediate level high/low-performance cultivars. weight trait was mainly negative incomplete dominance low-performance cultivar. seed yield had positive main control, while overdominance. According to analysis, highest general effects resulted cultivars Surkhan-14 (ĝi = 8.71) Bo'ston =1.86) for Guzor 0.12) genotypes Marvarid 2.44) 2.95) 2.3) 2.8) weight. × Surkhan-14, Bo'ston, desirable specific yield. Results concluded that Marvarid, can benefit as initial breeding material selecting high-yielding
