Abstract
The phenotypic variability of rice Oryza sativa L. androgenic doubled haploids lines (DH), intended for lodging resistance breeding, was studied. The lines used were obtained from F2 hybrids of the combinations Kitaets×(VNIIR23×Kenzo) - K×V×K (plants No. 26 and No. 28) and Don 4237× (Szorvasii 70× Heilunjiang) - D×Z×H (plant No. 8). Variety Primorsky 29 served as the standard. In 2020, DH lines and parental forms were grown under the conditions of a culture room in plastic cups filled with soil (temperature 25 °C, illumination 5000 lux, day 16 hours). In 2021 the seed offspring of the previous year were sown on the growing area in vessels 360×60 cm in size, 0.65 m3 in volume, filled with field soil. Each sample was sown in two rows, 25 plants per row. According to the ANOVA results, the DH lines and parental forms differed from each other in all characteristics in both years (p
