Barriers to hybridization of Solanum bulbocastanumDun. and S. VerrucosumSchlechtd. and structural hybridity in their F1 plants
@article{Hermsen2004BarriersTH, title={Barriers to hybridization of Solanum bulbocastanumDun. and S. VerrucosumSchlechtd. and structural hybridity in their F1 plants}, author={John G. Th. Hermsen and Munikote S. Ramanna}, journal={Euphytica}, year={2004}, volume={25}, pages={1-10} }
SummaryResults of reciprocal crosses between Solanum verrucosum (2n=2x=24) and S. bulbocastanum (2n=2x=24) are described in terms of pollen tube behaviour in styles, of berry and seed set, of fertility and of meiotic behaviour of the F1 hybrids. Pollen tube growth of S. verrucosum is strongly inhibited in styles of S. bulbocastanum, whereas no inhibition is observed in the reciprocal cross. Therefore S. bulbocastanum x S. verrucosum fails to set berries or seeds, whereas the reciprocal cross…

Production of Hybrids Between the 2EBN Bridge Species Solanum verrucosum and 1EBN diploid Potato Species
- BiologyAmerican Journal of Potato Research
- 2014
The objective of this study was to develop an efficient technique for using 1EBN species in breeding by crossing to 2EBN bridge species S. verrucosum, and to produce plants with the distinctive phenotypic characteristics and molecular markers specific to their1EBN parents.
Successful hybridization of non-tuberous Solanum etuberosumLind. and tuberbearing S. pinnatisectumDun.
- BiologyEuphytica
- 2004
It is suggested that this hybrid together with those between the tomato, Lycopersicon esculentum, and S, pennellii and S. lycopersicoides constitute piers of a bridge between tomato and potato species which in the future might enable gene transfer between these two crops via their wild relatives.
Introgression of resistance to late blight (Phytophthora infestans) from Solanum pinnatisectum into S. tuberosum using embryo rescue and double pollination
- BiologyEuphytica
- 2004
The view that transfer of valuable characters from S. pinnatisectum to S. tuberosum is feasible is supported; however, aneuploidy and the presence of univalents may inhibit this effort.

Each of these haploid-plant genomes is homozygous and is suitable for whole-genome sequencing, suggesting that the alleles are fixed in homoeologous loci.
Overcoming unilateral incompatibility in crosses with wild allotetraploid potato species Solanum stoloniferum Schldtl. & Bouchet
- BiologyEuphytica
- 2017
The germplasm of valuable for breeding wild allotetraploid potato species Solanum stoloniferum is rarely used because of pre- and postzygotic reproductive barriers with cultivated potatoes and one of the factors that complicate crosses is unilateral incompatibility (UI).

Wild diploid Solanum species with an endosperm balance number (EBN) of one are a rich source of disease resistance, pest resistance, and tuber quality traits. They are not sexually compatible with 4×…
Unilateral and bilateral hybridization barriers in inter-series crosses of 4x 2EBN Solanum stoloniferum, S. pinnatisectum, S. cardiophyllum, and 2x 2EBN S. tuberosum haploids and haploid-species hybrids
- BiologySexual Plant Reproduction
- 2005
It is found that pre- and post-zygotic barriers prevented seed formation in crosses involving S. stoloniferum, and the presence of functional and nonfunctional S-alleles may explain interspecific incompatibility in intra- and inter-ploidy crosses.

Evidence is presented that the 4x-F1's originated from unreduced gametes produced by two bulbocastanum accessions, and the genomic constitutions of the F1's adequately accounted for these fertility relations.

Experimental self- and cross-pollinations showed that the species is highly self-steriles and consists of cross-sterile and crossfertile individuals, which may be due to the presence of incompatibility factors or to triploidy.

- BiologyEuphytica

A critical cytological study revealed that meiosis in pollen mother cells is completely normal, and when eclipse sterility is involved, the nucleus in the young microspore does not divide any more after meiosis and some kind of plasmolytic process occurs in themicrospore leading to the characteristic eclipselike appearance.
