abstract:
Recombinat lines cv. Mercia with day-length inensitive genes (Ppd-B1) and control lines day-length sensitive (ppd-B1) were investigated. Experiments were conducted in Experimental Farm in Czeslawice. Number of days from 1st May to full ear emergence, plant height, number of spikelets in spike, number of grains in spike, weight of grains in spike, 1000 grains weight, spikelet fertility, plot yield and disease resistant were investigated. Ppd-B1 genes significantly influenced acceleration of ear emergence in recombinat lines. On the basis of these investigations favourable pleiotropic effects on plot yield were shown. Values of other quantitative traits in lines with Ppd-B1 genes and their control form were similar.
