THE QUALITY OF SUGAR BEET SEEDS AND THE WAYS OF ITS INCREASE - Ecological Consequences of Increasing Crop Productivity - page 180

In the variant of 50 percent of the plants of O-type minting and 100 percent plants
of its sterile analogue (MS component), there was a negligible deviation of variation
of the number of fl owers of the two components that makes 115.1-667.0 pc./plant for
a O-type and 162.5-750.8 pc./plant for the CMS component (Figure 18.2(c)).
Thus, minting of both plants of the O-type and of both components of breeding has
provided the synchrony of fl ower formation and their fl owering. Without the minting,
the fl owering of seed plants of O-type began and was fi nished in 2.1 times earlier, and
it took place more intensively at the beginning of fl owering and 1.3 times at the end of
fl owering, than that of the CMS component seed plants, that is, the fl owering of mat-
ing components was not synchronous (Figure 18.3(a)).

without—control, (b) under 50 percent of the plants of O-type, and (c) under 50 percent of
plants of O-type and 100 percent of plants of CMS component.
The minting of 50 percent of the plants of O-type has ensured the extension of its
fl owering term and more synchronous fl owering of the components (Figure 18.3(b)).
The fl owering of O-type was only in 0.64-1.03 times more intensively. Both at the
beginning of fl owering and its completion, the number of fl owers of CMS component
and O-type were almost the same. Thus, by the last date of accounting, the number of
