Microevolution of elements productivity of shoot spring soft wheat of the saratov selection

Authors: Gagarinsky E. L., Signaevskiy V. D.

The structure of elements of efficiency of runaway of summer soft wheat of the different grades created from the beginning of the XX-th century is analysed. Various tendencies in development of length of a stalk, number of spikelets and kernels an ear, weight kernels are revealed.

Structure of elements productivity introgression cultivarsand lines of spring soft wheat of the Saratov selection

Authors: Ilyin N. S., Gagarinsky E. L.

Within two years differing on weather conditions, the structure of a crop of spring soft wheat was studied. Comparison introgression grades and lines with genetically homogeneous grades has shown their approximate similarity on number of lateral shoot. The length of a stalk made on years of vegetation of plants from 469 to 605 mm, length of an ear − from 63 to 90 mm. The share of an ear from length of shoot varied from 10.9 to 14.6 %. The number of cones of an ear on the average for 2 years of studying made from 12.4 to 14.4 pieces.
