Lodging resistance of modern domestic rice varieties

Lodging is a complex process that expresses the plant's response to environmental factors. The main direction of breeding grain crops increase yields and improve quality indicators. For plants form maximum yield, it necessary develop varieties with high potential for productivity quality, resistance biotic abiotic In this regard, 5 new rice domestic were studied in comparison large-grain standard Favorit on an optimal background mineral nutrition they evaluated traits lodging resistance. experiment was carried out 2019-2020 under conditions field experment irrigation system experimental production department (ROS OPO) "FSC Rice" (Federal Scientific Rice Centre), Krasnodar. A significant difference established between terms anatomical morphological - values diameter lower internode (0.80 0.78 cm) observed VNIIR 10275 10254, respectively; predominant ratio height straw (90.8 120.7) at 10254 Veles; genotypes showed reliably stem bending value (165.75 g). important structural elements determined excess some them over variety revealed: density panicle Romans 10279 (12.2 11.8 pcs / cm); has large caryopsis largest weight 1000 grains 14% moisture content (43.1 g); 10279, one growing day (100.4 110.4 kg ha day) agrophytocenosis (50.00 58.19 thousand pieces m2) established. close positive relationship revealed stem's (r = 0.930), as well negative correlation average degree mass -0.552) -0.530). Based data obtained, decided transfer (Dialog) 2021 State Variety Testing (SVT).
