Influence study of the seed germination multigerm pollinators of the sugar beet on their productivity

Abstract

Goal. Studies conducted on Verhnyachskoy experienced-selection stations. Purpose of the studies was define the influence hereditary conditioned sign seeds germination new candidate in multigerm pollinators (МP) of the sugar beet on productive quality of the material. Conduct the selection perspective number posterity F1 and define efficiency of the selection on their improvement.
 Methods. Initial materials (IM) have served recombination (rk) МP foreign gene plasma productive rk БЗ4, БЗ5 БЗ6 БЗ7 and individual elections of their hybrids — synthetic, are received in result pollinate cross and have checked up crossbreeding, with high growing seed 80—95%. Standard — native pollinators Verhnyachkoy of an origin.
 Results. Phenologicheskie of supervision, laboratory germination seeds and test of a grade carried out in the standard methods [1, 2]. It is installed that high seeds germination have inherited the posterity under number 547, 556, 563, 564 (93—96%). We tie this as with weather condition under grow seeds so and ingenious selection component crossbreeding. Beside them is fixed satisfactory factors on productivities (45.3—50.3 t/h) in comparison to IM (42 t/h) and standard (38 t/h). Contents sugar from 19.51—20.21%, standard has got 19.44. Collection sugar was within 9—10 t/h (standard — 7, IM — 8 t/h). Satisfactory posterity productivity, probably, have got not only as a result favorable climatic condition at years of the test, but also in greater degree they are inherited from high productivity of the source parental forms.
 Conclusions. Have got the row new candidate in MP with improvement selection- and economic-valuable sign. Is established, that at creation new seeds of parental components of hybrids of sugar beet, it is necessary to take into account parameters of the genetic control of attributes of productivity, contents of sugar in IM and high quality of efficiency seeds. This spurs the posterity on temple ease of manufacturing, competitive ability and profit.
