Download scientific diagram | Análisis mendeliano de la autofecundación de una planta transgénica, que porta una copia del transgene que confiere tolerancia. A utilização da AI no melhoramento de plantas é feita há bastante tempo, mas .. a auto-incompatibilidade possa limitar a possibilidade de se autofecundar e. En Fitogenetecnia, se refiere a al capacidad de autofecundación de una planta, o al cruzamiento entre plantas, sin existir impedimento genético, morfológico o.

Inbreeding in sugarcane varieties

The existence of SI in economically important plants may be very important, being very positive in some cases or a burden in others, depending on the plant part harvested vegetative or reproductive and its mode of reproduction, sexual or asexual. Studies on successive inbred generations of selected sugarcane cultivars. The language you choose must correspond to the language of the term you have entered.

In the absence of over dominance in the genetic control of characters, it is theoretically possible to select recombinant individuals with superior performance than the parental clone, within the segregated populations derived from clones.

Soluble solids values varied around 0. Autogamy is sometimes referred to as self-pollination, but this is not a true [synonym of] autogamy. Both stalk height and stalk weight showed to be subjected to fairly strong inbreeding depression.
