Initial material for selection of calendula (Calendula L.) for suitability to mechanical harvesting of racemes

Abstract

The purpose. To determine initial material for creating grades of calendula, suitable for mechanical harvesting. Methods. Field, laboratory, mathematical and statistical. Results Characteristics of gene pool of samples of calendula are resulted according to their fitness for mechanical harvesting. Conclusions. Collection samples are arranged on a branchiness in 3 groups. The 3-rd group is fixed as perspective for further selection operation. Samples C.o.-99-3 and grade Radio are determined as the most perspective ones.
