The Contribution of Traditional Potato Breeding to Scientific Potato Improvement
Parental effects on the performance of cultivated 3 wild species hybrids in potato
Early generation selection at multiple locations may identify potato parents that produce more widely adapted progeny
The paper is called Early generation selection at multiple locations may identify potato parents that produce more widely adapted progeny. It was published in the journal Euphytica in 2012. The research was conducted by a group of 10 scientists. There are 7 parts and 11 tables.
Abstract covers the key information on the research conducted and results received.
Introduction explains why the development of new potato cultivars through breeding is a laborious and time-consuming process and describes the procedure of implementation of most potato breeding programs in the US. Besides, this part also contains the review of some studies dedicated to the selection of generation materials and their key results.
Materials and methods tells about the plant materials used for the study and analysis of the data received. The aim of the study was to find out if parents that produce progeny with broad adaptation could be identified early in the USDA/ARS Potato Breeding Program. During 3 years (2007–2009), seed of all second field generation clones was distributed to five locations for selection. In 2008, 2009 and 2010, selections weremade among 339, 321, and 381 clones, respectively. For each parent in each year, Chi-square values were calculated from the observed and expected number of progeny selected. Each year, parents that produced poorly- or broadly-adapted offspring were identified.
