The results in hybrid populations garden pea (Pisum sativum L.) by the number of vegetative nodes

Анотація

The main method of selection garden pea is currently the hybridization followed by individual and mass selection. Hybridization involves crossing a specially selected varieties to obtain better form. Under these conditions, the crossing of two varieties breeder is important to know the limits and nature of variability in F₂ and how the transition to full hybrid populations.

During the breeding necessary condition for the selection of new varieties. Its effects in populations check the original parental varieties, selected progeny plants, hybrids of different generations. Therefore, it is important to find methods of reasonably estimating received distinctions. The availability of such data is necessary for the proper operation of hybrid populations.

Many researchers in different crops based quantify the parameters that characterize the types of action and interaction of genes in the inheritance of quantitative traits and considering the ratio of dominant and recessive genes, was made the forecast efficiency of selection on major quantitative traits.

The aim of our study was to verify the forecast for garden pea.

Thus, two shot selection for "number of vegetative nodes" in early hybrid populations F₂ and F₃ in combination garden pea varieties №7019 / Alpha was achieved positive results. The coefficient of variation indicates a low level of variability of 8.0%. It was lower in relation to the population F₂ 14,2, F₃ - by 7.8%. Therefore, to achieve selective effect and steady, uniform of its manifestation, just one or two selections.
