Spectral assessment of varieties and breeding lines of winter wheat during the restoration of spring vegetation

The development of new and implementation existing methods field assessment winter wheat genotypes is one the key tasks modern breeding. use screening in breeding allows breeder to get a more objective assessment, as well increase volume studied samples several times. time spring vegetation recovery (TSVR) stages period wheat. Biometric spectral with onset TSVR establishing how plants certain genotype overwintered, state their growth before start second growing season. purpose this study was determine characteristics plant varieties promising lines V.M. Remeslo Myronivka Institute Wheat (MIP) from sowing restoration vegetation. hydrothermal conditions seedling-TSVR had diverse effects on reproductive process under study. According results, abnormally dry end autumn season 2019 adversely affected condition that were BBCH Phase 10-13, tillering did not take place. Regardless genotype, developed during first period. biometric parameters, at recovery, following turned out better than Podolyanka standard variety (NDVI = 0.52): MIP Dnipryanka 0.58), Lada 0.56), Balada Myronivska 0.56) Lutescens 37519 0.55) Erythrospermum 55023 0.58). During period, Dniprнanka 0.45) selection 0.44) 0.43) selected. an NDVI index value 0.43. react sensitively timing need longer accumulate matter pass rest
