Abstract:
It was found that the half-seed method by setting the control field in
spring and then the wintering field in rosette stage (15-20 well-developed leaves)
can maintain the variety in the allowable variability. Starting from the wintering
plants in the rosette stage, the average seed quantity was 50.7 g/plant, while plants
that overwinter in the head stage was only 28.8 g/plant. In the first case, floral stems
are more vigorous, showing an average height of 127.6 cm to 118cm average height
of floral stem in the second case. In 2014 was achieved an average production/ha of
1 574.5 kg conditional seed, to 1008 kg in 2015. Under the program for the
conservative selection, by applying rigorous selection methods, this variety has been
maintained within the allowable variability.
