METHOD TO INCREASE THE EFFECTIVENESS OF IDENTIFYING VARIETIES OF WINTER SOFT WHEAT

摘要

A method to improve the effectiveness of identifying varieties of winter soft wheat includes determining a typical form for a variety and selecting, according to morphometrical traits, the main ear, a glume, the shoulder and the carinate tooth of a glume, a caryopsis. The determinations of a typical form and sizes of the main ear, from the middle third of the ear, of a lower glume, the shoulder and the carinate tooth of a lower glume, a caryopsis are carried out for a variety. Then, according to a complex of the traits listed, thorough selection of 100 ears is carried out from a competitive variety trial plot, a reproduction seed field or in foundation seeds fields for the further reproduction and maintaining the variety, for improving the accuracy of the selections in the fields, which are distinguished by their larger evenness, and for obtaining homogenous plants of the next generation with the stable manifestation of the traits of the shape and sizes of the main ear (a length of 8.74+- 0.91 cm), a lower glume (a length of 8.98+- 0.80 mm, a width of 6.73+- 0.48 mm), the shoulder (a width of 1.23+- 0.28 mm) and the carinate tooth of a lower glume (a length of 3.42+- 3.08 mm, in bearded ones 5.03+- 2.77 mm, in beardless ones 0.59+- 0.14 mm), a caryopsis (a length of 7.14+- 0.39 mm, a width of 3.31+- 0.18 mm, a thickness of 3.03+- 0.17 mm).
