The method of seeds development for soybean breeding with in-creased resistance to charcoal rot and fusarium wilt

In article the description of a new method of seeds creation for soybean breeding with increased resistance to pathogenic agent of Charcoal rot (M. phaseolina) and Fusarium wilt (Fusarium spp.) is resulted. The method is based on an estimation of cellular sap' osmotic pressure (CAOP) in plant tissues during the critical periods of pod formation and seed filling, allowing to allocate forms of plants with osmotic pressure being in a range of values between 670 and 930 kPa. The bottom limit of CAOP in soybean should exceed critical value of this parameter (670 kPa) for the pathogenic agent of Fusarium wilt, leading degradations and destructions of its mycelium in host plant. Simultaneously CAOP shouldn't exceed the top limit of a range (930 kPa), being critical for the pathogenic agent of Charcoal rot and leading to mass formation of this fungi microsclerotium, corking spending soybean vascular system. Pressing out of cellular sap from the main stem tissues on the top part of shoots, and also in tissues of lateral shoots and rachis of composite leaves allow keeping on unique hybrid plants of a soybean the maximum amount of beans and seeds.
