SummaryThe growth habits, morphological characters and fertility features of the colchicine-induced polyploids of the following species have been described:S. chacoense, S. kesselbrenneri, S. rybinii, S. polyadenium, S. acaule, S. longipedicellatum, F1S. macolae × 5.simplicifolium and F1S. acaule ×S. simplicifolium. The crossability of the polyploids withS. tuberosum is indicated and the hybridization results are briefly discussed. The desirability of planning species hybridization in the… 

Modern taxonomic work on theSolanum species of Mexico and adjacent countries

  • J. Hawkes
  • Environmental Science
    American Potato Journal
  • 2008
TLDR
A general account of recent taxonomic work on the wild potatoes of this area is presented, with special reference to the ways in which modern experimental techniques have helped to solve problems of classification and evolutionary relationship.

Overcoming unilateral incompatibility in crosses with wild allotetraploid potato species Solanum stoloniferum Schldtl. & Bouchet

TLDR
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).

Development of chromosome-specific markers for a study on introgressive hybridization of potato with the wild Mexican allotetraploid species Solanum stoloniferum Schltdl

TLDR
The present paper presents the first results of the development of chromosome-specific DNA markers for the identification of S. stoloniferum chromosomes in interspecific hybrids.

Comparing Methods of Ploidy Estimation in Potato (Solanum) Species

TLDR
Three predictors of ploidy were tested, particularly seeking the quickest, simplest, and most reliable: Chloroplast number per guard cell (C#), guard cell length (GC), and pollen diameter (P), with a total of seven variations in methods of preparation.

Application of certain hormones to prevent flower abscission in two potato (Solanum tuberosum) varieties

  • M. Zafar
  • Biology

  • 2008
TLDR
Investigations in two potato varieties, namely, Canoga and Russet Burbank, indicate that in the Canoga variety, flowers and fruit were obtained when the plants were sprayed with any of the above-mentioned hormones at any stage, but the fully-grown-plant stage proved to be better for hormone treatment since it affects flower development.

Crossability ofSolanum tuberosum haploids with diploidSolanum species

TLDR
Twenty-four tuber-bearing diploid species ofolanum species, embracing 5 taxonomic series, were hybridized with haploids of the common potato, finding crossability of the haploids appears to be similar to the crossable of the cultivated diploids.

Mechanisms of interspecific incompatibility in tuber-bearingSolanum species

TLDR
Crosses in which the various mechanisms leading to a lack of seed formation that were encountered are listed are listed in this paper.

Crossability of some green-peach-aphid-resistant tuber-bearing solanums, potential bridging species, andSolanum tuberosum ssptuberosum

TLDR
Blue light fluorescence microscopy was found to be a quick and easy procedure for assessing pollen tube development in interspecific pollinations ofSolanum and should be considered for embryo culture.

Overcoming hybridization barriers in potato

TLDR
Cross barriers between most wild species and the cultivated potato are the consequence of differences in EBN and can be easily overcome using ploidy manipulations and bridge crosses.

The use of foreign introductions in breeding American potato varieties

TLDR
Though many of the varieties developed by the breeders of the 19th century have disappeared from general agricultural production a few of the best adapted, particularly P, usset Burbank, Irish Cobbler, White Rose, Triumph, Red McClure, Green Mountain, Russet Rural and Early Ohio, are still very important commercially.

Preliminary account on a new amphidiploid:Solanum artificiale

TLDR
Among the wild and cult ivated tuberbear ing species of the genus Solanum immuni ty to Phyt@hthora in[estans is only met with in the Mexican species S. demissum, S. Antipoviczii is immune to all strains of Phytophthora in/estans and is hardly used in this kind of breeding work as it is very difficult to get hybrids of this species with .

The effect of chromosome doubling on the crossability ofSolanum Chacoense, S. Jamesii, andS. Bulbocastanum withS. Tuberosum

TLDR
It is indicated that there are desilable, heritable characters appearing in S. bulbocastanum, S. chacoense, and S. ]amesii which would be of practical value if they could be incorporated in commercial varieties.

Chromosome doubling in potatoes induced by colchicine treatment

TLDR
Polyploidy has been induced in the Russet Rural and Golden varieties of Solanum tuberosum and in seedling of U. S. lines S.164–126 and S. 164–196 in Louisiana line T3–4.

IV.—Inheritance of Resistance to Two Strains of Blight (Phytophthora infestans de Bary) in Potatoes

  • W. Black

The existence in Mexico of blight-resistant species of potato has been known for many years, but they occur in the wild and are quite unsuitable for agricultural purposes. In order to utilise their

Physiology of incompatibility in plants

TLDR
The aim of the study is to determine the carrier and removal of S genes from pollen that are carriers and those that are removal candidates are removed from pollencollectors.
