Hybridity and autopolyploidy increase the expressivity of apospory in diploid Paspalum rufum
(Springer Wien, 2016-08)
Paspalum rufum Nees is a perennial grass that forms a multiploid complex. natural populations are composed mainly of diploid (2n = 2x = 20) and tetraploid(2n = 4x = 40) cytotypes. The diploid form is sexual and highly ...

Seasonal expression of apospory in bahiagrass
(CIAT, 2013-09)
This paper was presented at the 22nd International Grassland Congress, Sydney, Australia, 15−19 September 2013. Its publication in Tropical Grasslands – Forrajes Tropicales is the result of a co-publication agreement with ...
Heterochronic reproductive developmental processes between diploid and tetraploid cytotypes of Paspalum rufum
(Oxford University Press, 2019-05)
BACKGROUND AND AIMS: Apomixis is an asexual reproductive mode via seeds that generate maternal clonal progenies. Although apomixis in grasses is mainly expressed at the polyploid level, some natural diploid genotypes of ...
Heterosis, and expressivity of apospory in tetraploid Bahiagrass hybrids
(Crop Science Soc Amer, 2015-05)
Breeding procedures developed for apomictic species are based on the idea of fixing superior hybrids by apomixis. However, scarce information is available about the occurrence of heterosis in apomictic hybrids. The objective ...

Apospory followed by sterility in a hypotriploid hybrid (2x X 4x) of Paspalum
(Univ Florence Botany Inst, 2004-12)
A self-incompatible diploid plant (2n = 2x = 20) of Paspalum limbatum grown in a field nursery surrounded by tetraploid accessions of several Paspalum species produced a hypotriploid descendant (2n-1 = 3x = 29). Molecular ...

Identification of a molecular marker linked to apomixis in Brachiaria humidicola (Poaceae)
(Wiley-Blackwell Publishing, Inc, 2010-12-01)
P>A bulked segregant analysis using RAPD technique was carried out to identify molecular markers linked to apomixis in a Brachiaria humidicola F(1) population that segregated 1 : 1 for the mode of reproduction (apomixis ...
