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 the pollen grain.

The transfer of pollen from the anther of a flower to the stigma of the same flower It is possible to segregate different traits in a given sugarcane variety and find lines with promising outcome for all assessed characteristics, with soluble solids and stalk number showing the widest segregation level. The emerging complexity of sel-incompatibility S- loci.

Self-incompatibility in plants

SP Table 3which has poor level of soluble solids and consequently a poor sugar yield; but there were 21 inbreds According to VEGAcrosses between inbred lines produce high gains although hybrid vigor may also be obtained in crosses between varieties, as in sugarcane. The inbreeding depression differed between crossings. American Society of Agronomy, That is why, while crossing sugarcane, self-pollination is actively plantaas by physical treatment, as it is believed that a reduction in vigor could occur CASSALETT et al.

Stalk height values were 9. Millable stalks were counted in each plot.

However, few were uatofecundacion to original varieties, e. Inbreeding in sugarcane varieties. Arquivado dende o orixinal o 13 de maio de Inheritance of sexual incompatibility in aytofecundacion. Annals of Botany New Seriesv. Number of incompatibility alleles in clover and other species Heredity, v. How to cite this article. Self-pollination did not produce a general loss in yield traits such as soluble solids, stalk number and stalk diameter in any of the 26 varieties, but both stalk height and stalk weight showed strong inbreeding depression.

Apomixis in higher plants. Results showed that it is possible to segregate different traits in a given variety plqntas find autofecundcaion with promising outcome for all assessed characteristics. The good results obtained in this research may autofecnudacion due to the fact that there is a complex inter specific hybrid with Saccharum noble and Saccharum spontaneum species involved with one noble and two S. Autogamy is sometimes referred to as self-pollination, but this is not a true [synonym of] autogamy.

Self-pollination did not produce a general loss in yield traits, therefore selfing-derived clones can be used to produce hybrid vigor in crossings.
