Usefulness of Andigena (Solanum Tuberosum SSP. Andigena) Genotypes as Parents in Breeding Early Bulking Potato Cultivars

Abstract: Seven Solanum tuberosum ssp. tuberosum and three Solanum tuberosum ssp. andigena accessions were crossed to produce 12 Tuberosum × Tuberosum (T × T) and 9 Tuberosum × Andigena (T × A) progenies. These families were evaluated for five important traits for two successive clonal generations under short day sub-tropical plains. The differences in yield, average tuber weight and tuber number between T × T and T × A families in an early (75 days) crop were not significant. Compared to conventional intra-Tuberosum fa… Show more

“…It is cultivated at altitudes as high as to 3500 m above sea level ( Terrazas et al , 1996 ) and is therefore adapted to harsh climate conditions. Its similar tetraploid genome allows for hybrid generation with Tuberosum ( Kumar and Kang, 2006 ; Tai and Tarn, 1980 ). Therefore, Andigena is an ideal candidate to study genes related to drought tolerance that in the future could be introgressed into Tuberosum.…”

“…Inter-mating such distantly related selections may lead to highly heterozygous populations for the selection of superior clones. Genetic uniformity characterizing current potato cultivars suggests that gains can be made from increased heterozygosity which in potato is known to be essential to realize heterosis for economic characters such as tuber yield (Cubillos & Plaisted 1976;Gopal et al 2000;Kumar & Kang 2006). High inbreeding coefficient affects yield in potato (Loiselle et al 1991).…”

“…Details of the population improvement schemes for quantitative resistance to late blight under high endemic disease pressure in the Andean highlands (B populations), and for virus resistance in the lowland tropics (LTVR), together with other desirable traits, can be found in the book chapter by Bonierbale et al (2020). Furthermore, in the Central Potato Research Institute of India there was interest in Tuberosum (female) × short-day Andigena hybrids in breeding for the sub-tropical plains where the potato crop is grown under short days (Gopal et al 2000;Kumar and Kang 2006).…”
