| description | The current paper has presented the study results on estimating the effect of the upper leaves’ area of winter bread wheat samples on productivity and its elements. There have been tested nine winter bread wheat varieties of intensive type developed in the FSBSI “Agricultural Research Center “Donskoy”. The current study has identified that the largest upper leaves’ area under insufficient moisture supply during the periods of head formation and flowering was produced by the variety “Etyud” (31 cm2 in a heading period; 29.4 cm2 in a flowering period). During the period of milky kernel ripening, the variety “Shef” has also shown the largest upper leaves’ area under insufficient moisture supply (17.7 cm2). The variety “Yubiley Dona” has shown a minimal decrease in the upper leaves area to milky kernel ripeness (40%). The evaluation results of productivity and its structure have shown that the largest value of the number of productive stems per 1 m2 in arid conditions was identified in the varieties “Etyud” (261 pcs.) and “Shef” (254 pcs.). According to the number of kernels per main head, the variety “Donskaya Step” was the best with 32 pcs. Large kernel weight per main head was identified in the varieties “Donskaya Step” (0.72 g), “Shef” and “Etyud” (0.67 g), and according to 1000 kernel weight the varieties “Etyud” (25.9 g) and “Zodiak” (25.2 g) were the best ones. The varieties “Etyud” (163.7 g/m2) and “Shef” (168.6 g/m2) have produced the maximum yields, that means the best functioning of all productive systems of winter bread wheat. The estimation of the samples according to the correlation between photosynthesis efficiency of the upper leaves’ area and kernel percentage (ZFL) has identified the samples “Donskaya Step”, “1005/14”, “Univer”. According to the correlation between photosynthesis efficiency of the upper leaves’ area and kernel weight per head (MFFL) the variety “Donskaya Step” showed the best results. The conducted study ad obtained results made it possible to identify the varieties “Shef”, “Etyud” and “Donskaya Step”. The identified varieties have been proposed for further use in the breeding process. |
