Comparison of Different Approaches to Establish a Core Collection of Andigena (Solanum tuberosum Group Andigena) Potatoes

Potato Research, 2013
A core collection of germplasm is a representative set of accessions capturing the complete genetic diversity of the entire collection with minimum repetitiveness. In the present study, in order to develop a core set from an entire collection of 740 accessions of Andigena potato (Solanum tuberosum Group Andigena), data were recorded on 21 morphological

Crossability ofSolanum tuberosum Gp. Andigena haploids

American Potato Journal, 1979
The crossability of Group Andigena haploids was investigated in this study. Groups Phureja, Stenotomum and Tuberosum haploids were crossed to Gp. Andigena haploids reciprocally to estimate the female and male fertility of the latter. The male fertility of Gp. Andigena haploids was reflected by the average seed set from crosses to Gps.

Haploid extraction inSolanum tuberosum group Andigena

American Potato Journal, 1978
Haploids were extracted from 66 differentSolanum tuberosum Group Andigena introductions usingS. tuberosum Group Phureja clone 1.22 as pollinator. The overall frequency of haploids was 13 per 100 fruit, with a high of 106. The overall average number of seeds per fruit was 1.4.

Tuberosum x Tuberosum and Tuberosum x Andigena potato hybrids: comparisons of families and parents, and breeding strategies for Andigena potatoes in long-day temperate environments

Theoretical and Applied Genetics, 1983
Tuberosum x Tuberosum families and Tuberosum x long-day adapted Andigena families are compared with each other and with their parents using multivariate analyses. The Tuberosum x Tuberosum families, representative of those used in present-day breeding programs, have lower mean tuber weights, marketable yields and total yields than their parents, and a ...

Yield and fertility of reciprocal-cross Tuberosum-Andigena hybrids

American Potato Journal, 1980
Reciprocal yield differences were found in Tuberosum-Andigena potato hybrids. Progenies with Tuberosum female and Andigena male parents (TA’s) outyielded their reciprocals (AT’s) in tests conducted over five seasons in New York. Differences ranged from 12 to 32%.

Genetic variation in Solanum tuberosum group Andigena haploids

Theoretical and Applied Genetics, 1982
A random sample of haploids, derived from 28 parental introductions from Solarium tuberosum Gp. Andigena, was used to estimate the quantitative genetic variation for six traits within this group. The six traits analyzed on a plot mean basis were: total tuber weight, fresh vine weight, total fresh weight (tuber+vine), dry vine weight, total dry matter ...

Flower production, male sterility and berry setting in andigena potato

Theoretical and Applied Genetics, 1989
Unlike tuberosum, andigena potato germ plasm exhibits a high degree of genetic variation in morphological, biochemical and reproductive traits. Sixty-five percent of the 565 genotypes comprising 145 accessions of Solanum tuberosum ssp. andigena obtained from Argentina, Bolivia, Chile, Colombia and Peru remain totally vegetative and never develop any ...
