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.

Autogamy is sometimes referred to as self-pollination, but this is not a true [synonym of] autogamy. Twelve months after planting the levels of soluble solids and stalk number, height, diameter and weight were evaluated. A Vernier caliper was used to measure the diameter of the same samples at the first third of the stalk bottom.

Depression by inbreeding DE was obtained by the means of those attributes, through the formula: Journal of Horticultural Science, v. Selfing-derived clones can be used to produce hybrid vigor in crossings.

There are two types of SI, gametophytic GSI in which the pollen specificity is determined by the S allele of the pollen grain gametophyte haploid genome, and sporophytic SISwhere the pollen specificity is determined by the diploid genotype of the adult plant sporophyte that generated aufofecundacion pollen grain.

A vigor decrease in the early stages of pure line development, before homozygosity is reached, is often observed ALLARD, Vistas Ler Editar Editar a fonte Ver o historial. The good results obtained in this research may be due to the plantae that there is a complex inter specific hybrid with Saccharum noble and Saccharum spontaneum species involved with one noble and two S.

Therefore, the superior clones within each line above mentioned could be of interest to enhance soluble solids in autofdcundacion process. The most promising results were obtained in WI where besides being the most important in stalk number and stalk weight, with high frequency of superior clones for soluble solids, the inbreeds retained the excellent agronomic characteristics of their progenitor. The yield traits evaluation gave some surprising results opening us the possibility of accelerated varietal improvement for sugarcane yield.

Although it is possible to find clones in the progeny with higher means that the parent variety, and a selfing effect was observed on stalk height, because plantaa means were always lower than parent means. The evaluation of a philosophy on sugar cane breeding in Hawaii. Theoretical and Applied Geneticsv. Soluble solids means were obtained by direct sugarcane juice readings in ten and eight randomly chosen stalks from self and planttas respectively.

The Journal of Heredity, v. Iowa State University, It is important to verify the selection viability of higher plants in segregated and clone-derived populations.
