“…Nevertheless they have been described for a considerable number of species. In combination with a recessive male sterility gene, for example, dominants have been claimed for the wild species Origanum vulgare (Lewis and Crowe, 1956), Cortaderia richardii (Connor, 1973) and Mercurialis annua (Louis and Durand, 1978) and also for cultivated species like Zea mays (plasmon N, Schwarz, 1951), Triticum aestivum (Wickersham and Patterson, 1980), Lactuca sativa (Ryder, 1963), Phaseolus vulgaris (Mutschler and Bliss, 1980) and Petunia hybrida (Van Marrewijk, 1969).…”

SUMMARYInheritance of male sterility has been studied in Plantago lanceolata. Crosses between plants, obtained from a 50 m2 area, yielded the entire array of possible sex phenotypes. Emphasis is put on nuclear inheritance of two nuclear-cytoplasmically determined male sterility types. In both types multiple interacting genes are involved. For MS1 a combination of two recessive and three dominant male sterility genes is proposed, for M52 three recessives. These are minimum estimates as the exact numbers could not be determined. One of the loci for MS2 is probably linked to the self-incompatibility locus. Not all results can be explained this way, which emphasizes the complexity of nuclear inheritance. Intermediates between the completely male steriles of both types and hermaphrodites constitute two continuous series, each consisting of multiple genotypes with overlapping phenotypes. Segregation patterns indicate genetic determination by incomplete dominance at the male sterility loci. A third male sterility type (MS3) is described whose expression appears to be independent of plasmon type. Preliminary results indicate two duplicate recessive male sterility genes.The stability of the complexity of nuclear inheritance for gynodioecy is discussed.

“…Temperature is known to be an important factor in the restoration of male fertility (Frankel & Galun, 1977;Kaul, 1988;Tracy et al, 1991), but the response of different species is not uniform. Some authors report an increase of male sterility with increasing temperatures (Van Marrewijk, 1969;Kaul, 1988;Barrett & Harder, 1992), others report the reverse (Burns, Scarth & Mcvetty, 1991). Also, genotypic differences in the degree of male sterility in response to temperature are known (Martin & Crawford, 1951;Van Marrewijk, 1969).…”

Sl'MMAKVGynodioecy is a breeding system consisting of male steriles (MS, females) and hermaphrodites (H), Tbere is how ever within such systems a third, often neglected, class of partially male sterile plants (PMS), i,e, plants with an intermediate sex expression. In tiatural populations of Plantaf;o coronopus, partially male sterile individuals were as common as male steriles (frequencies in tbe range 1'7 36-8",,). These PMS plants constitute a continuous series, linking compk-te male sterility and hermaphroditism. We discovered that temperature influenced sex expression and the degree of male sterilit\ of PMS indi\iduals, but not of AIS and H individuals. Thus, at higher temperatures PMS individuals became more male sterile. Difference in c\ toplasmic background ofthe indi\'iduats did not infiuence their response to temperature. IT is argued tbat partial male sterility is a normal feature of eytiodioecious species and not an abnormality,

“…Besides, cytoplasmic male sterility may be of interest for increasing flower longevity and for controlling the dispersion of invasive species. Although we have not tested the effect of different environmental conditions on cytoplasmic male sterility and fertility restoration, it is likely that they play a role on the expression of these characters, as it has been shown in several species ( VAN MARREWIJK, 1969;IZHAR, 1975;DHALL, 2010;DE STORME and GEELEN, 2014;BUECKMANN et al, 2016). Future research should consider this aspect to better describe the expression of the male sterile cytoplasm of calibrachoa.…”

Calibrachoa pubescens is a species native from the south of Brazil, Uruguay and northeast Argentina. An accession identified as 7.3.1.1 was collected at San Martín Department in Corrientes Province, Argentina and is included in the calibrachoa breeding program at the Institute of Floriculture, INTA. This accession is male sterile and produces male-sterile progeny, characterized by the lack of pollen production. Male sterility may be controlled by nuclear or cytoplasmic genes with each type presenting a different mode of inheritance. The objective of this research was to present a novel source of cytoplasmic male sterility in Calibrachoa pubescens. Crosses were made in the greenhouse between the male-sterile line 7.3.1.1 as the female parent and seven male-fertile lines of diverse origin. F1s were backcrossed and self-pollinated. Individual plants of the progenies were classified as male-fertile or male-sterile according to pollen viability. Analyses of observed segregations showed that male sterility observed in 7.3.1.1 results from the interaction of a male sterile cytoplasm and nuclear restorer genes. A novel male sterile cytoplasm is now available for breeders. Main advantages of cytoplasmic male sterility in ornamentals breeding are: efficient hybrid production, increased flower longevity, avoidance of pollen allergens and control of plant invasiveness. Keywords: Calibrachoa pubescens, cytoplasmic male sterility, fertility restoration, ornamental breeding. RESUMO Uma nova fonte de esterilidade masculina em Calibrachoa pubescensCalibrachoa pubescens é uma espécie nativa do sul do Brasil, Uruguai e nordeste da Argentina. Um acesso identificado como 7.3.1.1 foi coletado no departamento de San Martín, no estado de Corrientes -Argentina e incluído no programa para o melhoramento genético de Calibrachoa no Instituto de Floricultura, INTA. Esse acesso é macho-estéril e produz progênies masculinos-estéreis, caracterizada pela falta de produção de pólen. A esterilidade masculina pode ser controlada por genes nucleares ou citoplasmáticos cada um dos quais apresenta diferentes mecanismos de herança. O objetivo desta pesquisa foi presentar um novo citoplasma masculino estéril em Calibrachoa pubescens. Os cruzamentos foram feitos em estufa entre a linhagem macho-estéril 7.3.1.1 como genitor feminino e sete linhagens masculinas e férteis de origem diversa. Os F1s foram recortados e auto-polinizados. Plantas individuais das progênies foram classificadas como masculinas férteis ou macho-estéril de acordo com a viabilidade do pólen. As análises das segregações observadas mostraram que a esterilidade masculina observada em 7.3.1.1 resulta da interação de um citoplasma estéril masculino e genes restauradores nucleares. Um novo citoplasma masculino estéril está agora disponível para melhoradores. As principais vantagens da esterilidade masculina citoplasmática no melhoramento de plantas ornamentais são: produção híbrida eficiente, aumento da longevidade das flores, ausência de alérgenos do pólen e controle da invasivida...
