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.

How does self-pollination evolve? A stalk puncher was used to obtain a juice sample from the center of the mid portion internodes, in each millable stalk per row. Autogamy is sometimes referred to as self-pollination, but this is not a true [synonym of] autogamy. A high rate of tall seedlings was observed in SP, which produced a high frequency Seasonal and population differences in a grass. Selfing varieties with high diameter of the stalks i.
Self-compatibility and heterosis in white clover Trifolium repens L.
Existem diversos maneiras de superar a barreira da AI. Sugarcane varieties have the advantage of vegetative propagation, which keeps the hybrid combinations.
S-locus receptor kinase genes and self-incompatibility in Brassica napus. Seedlings F2 and their parents were set out in a randomized complete block design with 26 treatments each, totalizing 52 treatments, with four replications, with row spacing of 0.
Soluble solids means were obtained by direct sugarcane juice readings in ten and eight randomly chosen stalks from self and parents respectively.
Sugarcane species are allogamous, i. Characterization and breakdown of self-incompatibility in field bindweed Convolvulus arvensis L. Hereditas, v 52, p. Pollen-stigma signaling in the sporophytic self-incompatibility response.
Biometric agronomic traits are important in the final weight components of sugarcane stalks SILVA et al. Selfing-derived clones can be used to produce hybrid vigor in crossings. Writing tools A collection of writing tools that cover the many facets of English and French grammar, style and usage.
Results showed that it is possible to segregate different traits in a given variety and find lines with promising outcome for all assessed characteristics. Access a collection of Canadian resources on all aspects of English and French, including quizzes.
Self-incompatibility in plants
The intracellular events triggered by the self-incompatibility response in Papaver rhoeas. Apomixis in higher plants.
Both stalk height and stalk weight showed to be subjected to fairly strong inbreeding depression. Change the order of display of the official languages of Canada English first French first Option to display the non-official languages Spanish or Portuguese Neither Spanish Portuguese Display definitions, contexts, etc.
Services on Demand Journal. PCP-A1, a defensin-like Brassica pollen coat protein that binds the S locus glycoprotein, is the product of gametophytic gene expression.
An association between variability in ovule development within ovaries and self-incompatibility in Lotus Leguminosae. There are two types of SI, gametophytic GSI in which the pollen specificity is determined by autofecundacjon 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 the pollen grain.
The evaluation of a philosophy on sugar cane breeding in Hawaii. Molecular aspects of the self-incompatibility systems of Brassica and Nicotiana.
Self-pollination in sugarcane hybrids, Saccharum sp. These results indicate that self-pollinations with higher depressions within each parameter have more heterozygous loci than null or low depression self. Genetics Plant and Crop Production. Canadian Journal of Plant Sciencev.
But, in a general way, selfing promoted reduction in average stalk diameter. The wide segregation for stalk height and stalk autofecundaciob permitted the selection of Espazos de nomes Artigo Conversa. The most promising autoffecundacion 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.
As a possible means to overcome the ceiling on sugarcane production, this research was initiated with plwntas group of parental varieties to obtain and evaluate first-generation inbred lines that may be used for further crosses and to determine also the extent of inbreeding depression. In which subject field?
A line which has been selfed for several generations resulting in a high degree of homozygoty.
