EFFICIENCY OF SELECTION ON HIGH TILLERING AT VARIOUS DENSITY OF PLANTING OF RICE PLANTS
06.00.00 Agricultural sciences
Description
In the article, the estimation of efficiency of selection on high tillering is given at various planting density. For the analysis used plants of variety Lampo with high tillering ability and varieties the Virazh and Ko-mandor - with weak tillering ability, and hybrid popu-lations F3 from their crossing, selected on traits high and low tillering from F2. Plants ¬ placed on plots in three variants: 2×15, 15×15, 30×30 cm. It is estab-lished that distinctions on tillering between “+” and “–” selection in following generation remain, though the value of given trait at hybrid plants decrease. Selection of highly tillering forms at usual density (2×15 cm) has shown high efficiency, because the tillering is caused by more influence of genetic factors, than environment in the given variant
