Studies of Oat-Maize Hybrids Tolerance to Soil Drought Stress

The ontogenesis and yield formation in crop plants are modified by environmental conditions. Due to climatic change detected over two decades, the harmful influence of abiotic factors is increasing. One most threatening issues reducing plant productivity drought stress. strength response water shortages could differ depending on stress, type crop, genetic background, presence additional stresses, stage development. There examples sexual hybridization between like oat (Avena sativa L.) maize (Zea mays with which stable fertile hybrids were generated. Additional chromosomes (oat × addition, OMA) often infer morphological physiological (e.g., PS II photosystem activity chlorophyll production) changes modulated interaction certain added genome. aim research was evaluate chosen physiological, biochemical, agronomic parameters OMA subjected soil drought. Analysis variance indicated that main effects genotype as well treatment significant for all traits studied (photosynthetic pigment content, selected PSII indices, mass stem, number grains/plant, grains/plant). Most examined lines severely reduced parameters, yield-related under results (9 78b) retained high yielding potential stress compared commercial cv. Bingo.
