Selection of sources with superior agronomic traits from F3 hybrid generation soybean genotypes

This study investigated the selection of promising lines with valuable agronomic traits from F3 hybrid generation plants of soybean (Glycine max (L.) Merr.). Eight different hybrid combinations were evaluated based on morphological and yield-related traits. According to the results, the ♀Ehtiyoj × Nena♂ combination showed the highest performance in terms of number of pods (183.5 ± 13.01), number of seeds (370.3 ± 35.76), and seed weight (61.81 ± 4.99 g). Additionally, the “Tezpishar” line derived from the Sochilmas × Genetik-1 hybrid was notable for maturing within 70 days, which is significant for the development of early-maturing varieties. The results are consistent with data reported in international literature and confirm the potential for developing high-yielding and climate-adapted new cultivars under the conditions of Uzbekistan. The selected lines are recommended as promising genetic material for further improvement to cultivar level and enrichment through molecular breeding techniques.
