Aims. Installing the correlation between the main indicator productivity — seed weight per plant and other quantitative
 traits of soybean; study the effectiveness of selection on one of the selective traits in hybrids F3
 –F5
 of soybeans.
 Methods. The study was conducted in hybrid and breeding nurseries of soybean of Institute of irrigated agriculture
 NAAS for 2007–2009, growing technology is common for irrigation conditions of southern Ukraine. The generalization
 of correlation coeffi cients quantitative traits was performed by the method of J. William Snedekor; bonding force was
 determined by B. Dospyehov. Results. We have analyze a correlations between weight of seeds per plant (the basic index
 of productiveness) and other quantitative trait of soybean; selection effectiveness for productivity of soybean hybrid
 populations F3
 –F5
 by number of productive nodes from plant. There are the characteristics of new soybean varieties that
 had made by improved method of selection in the article. We have received the positive average correlation between
 weight of seeds per plant and stem thickness, stem bottom thickness, quantity of branches on the plant and number of
 productive nodes on a main stem. We have obtained strong correlation between weight of seeds per plant and number of
 productive nodes on branches, productive nodes on a plant, bean’s quantity per plant, quantity of seeds per plant, plant
 weight and weight of beans. Conclusions. Signs that had a strong positive correlation with seed weight per plant, we can
 assume factorial and apply in the selection to improve productivity of soybean. Selection on the number of productive
 nodes on the plant are most effective for increasing seed mass per plant.
