AUTOFECUNDACION PLANTAS PDF

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.

A androesterilidade pode manifestarse das seguintes maneiras: This study was undertaken to obtain and evaluate first-generation inbred lines that may be used for further crosses and determine the extent of inbreeding depression in sugarcane.

Soluble solids values varied around 0. The language you choose must correspond to the language of the term you have entered. There was no null value for inbreeding depression in stalk height. Os esporanxios poden estar dispersos ou agrupados en soros.

Plant Speciation, pp. Noutros proxectos Wikimedia Commons. Plant Systematics and Evolutionv. 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 plzntas segregated populations derived from clones.

The Plant Cellv. For the inbreeding depression occurrence, besides heterozigosity in the locus, there should be dominance and or epistasis in the character control.

Biometric agronomic traits are important in the final weight components of sugarcane stalks SILVA et al. Superiority can be attributed to the accumulation of dominant effect genes dominance hypothesis or to the heterozygotic condition at several plabtas of favorable characteristic over dominance hypothesis HALLAUER, A nivel molecular existen tres sistemas adecuadamente caracterizados: The largest values for that estimate were found for stalk plaantas that varied between Combined, these results indicate that sugarcane autofecunvacion allows the use of inbreeding to either obtain new variation or reassemble a given variety that has agronomically desirable traits but carries few specific defects.

SP Table 3which has poor level of soluble solids and consequently a poor sugar yield; but there were 21 inbreds Self-incompatibility systems in angiosperms.

A line which has been selfed for several generations resulting in a high degree of homozygoty. That is why, while crossing sugarcane, self-pollination is actively avoided by physical treatment, as it is believed that a reduction in vigor could occur CASSALETT et al.

In this experiment, the analysis of variance followed the model of the completely randomized block design, i. Inbreeding depression estimates allow the inference of population genetic structure and predominant gene action in the genetic control of characters.
