The effect of the elements of structure on productivity of the lines of leafless peas

Abstract

One of the reasons of peas sowings decrease are the shortcomings of its cultivation, especially its wrong harvesting that together with its biologic peculiarities makes its cultivation rather difficult. Wrong technologies of cultivation result in peas fall and its severe lodging that largely reduces its yield and in climatic unfavourable years leads to the loss of it. The varieties of leafless peas which form a hard stand and do not lodge play a significant part in the solution of the problem. The article gives the results of the effect of the elements of structure on productivity of leafless peas. Nine peas lines of the competitive variety testing have been studied. The characteristics according to the main economic-valuable traits, i.e. productivity, a number of beans per plant, a number of seeds per bean, a number of nods and 1000-seed weight, has been given. The line ‘SarmatxAksaysky Usaty10’ with the maximum productivity of 2.3 t/ha is of greatest interest. The line ‘Aksaysky Usaty10xSarmat’ possesses the largest 1000-seed weight (177.4g). The line ‘Aksaysky Usaty7xSarmat’ possesses the largest number of bean per plant (4.1 pieces). The lines ‘Flagman 7xZernogradsky9’, ‘PriazovskyxSarmat’ and ‘SarmatxAksaysky Usaty55’ possess the largest number of seeds per bean (4.5; 4.2; 4.2 pieces respectively).
