“…In contrast, early generation selection has been more successful when focused on only one trait with high heritability, such as cold chipping (Hayes and Thill 2003) or virus resistance (Swiezynski 1984). Thus, it has been recommended that negative selection be applied in early generation selection (Davies and Johnston 1974;de Galarreta et al 2006;Gopal et al 1992;Tai and Young 1984). Maris (1988) recommended a selection intensity of 40 % for the first clonal generation.…”

“…The U.S. Department of Agriculture, Agricultural Research Service Potato Breeding Program in Beltsville, MD (ARS) typically saves only 2-3 % of these progeny. Nevertheless, several researchers have questioned the reliability of selection at this stage (Davies and Johnston 1974). Others (Caligari et al 1986) have gone so far as to suggest that selection in the first field generation results in a random reduction in the number of clones.…”

Early generation selection at multiple locations may identify potato parents that produce more widely adapted progeny

Potato production in the eastern United States occurs over a wide range of environments from Maine to Florida; many of these states do not have a breeding program. Initial selections are usually made at the breeding location for more than 2 years before undergoing evaluation elsewhere, at which point, few clones remain from the original population. The purpose of this study was to determine if parents that produce progeny with broad adaptation could be identified early in the USDA/ARS Potato Breeding Program. For 3 years (2007)(2008)(2009), seed of all second field generation clones was distributed to five locations for selection. In 2008, 2009 and 2010, selections were made 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 broadlyadapted offspring were identified. Among the progeny selected at three or more locations, 27 to 70 % had not been selected by the breeding program. Early generation selection can be used to identify parents that produce broadly adapted progeny and may identify broadly adapted progeny before they are discarded by the breeding program. Because potatoes display such strong genotype 9 environment interactions, this selection approach may be particularly beneficial for selecting potato cultivars with broad adaptation.

“…A high proportion of the clones selected in C2 would always have been discarded in S or C1. Davies and Johnston (1974) reported that in C1 stage single-hill system selection was ineffective even when clones were replicated twice, as very small percentage of clones selected from two replications were same. Neele et al (1988) reported that the use of two-plant plots instead of one-plant ones in C1 helped reduce the environmental variance, but it had only slightly positive effect on the selection efficiency.…”

The success of any potato breeding programme depends upon the selection of superior parents and cross combinations, and superior clones from the segregating progenies. However, due to the tetrasomic inheritance and heterozygous nature of cultivated potato, potato breeding has remained empirical, cumbersome and timeconsuming. Potato breeders have used a number of approaches to simplify and improve the efficiency of potato breeding. These include use of mid-parent/mid-self values, genetic diversity, combining ability, estimated breeding values and progeny tests for the selection of parents and cross combinations. The selection of superior clones from the segregating progeny has been hampered by low efficiency of selection in early generations particularly for tuber yield and its components. The possibility of in vitro selection and production of microtubers for early large scale trials has been explored. The procedures used and constraints observed are reviewed and discussed in this paper.

“…Traits such as yield, specific gravity, plant appearance (Davies & Johnston, 1974;Brown et al, 1984Brown et al, , 1987Tai & Young, 1984) and chip color from progenies (Neele & Louwes, 1989) have been particularly emphasized as selectable. Most important for the chip industry is an emphasis on chip color because if a desirable color is not present, then the relative importance of remaining traits is diminished.…”

Potato (Solanum tuberosum) breeding and selection programs aim to develop new cultivars of superior and improved qualities. Early generation selection plays a critical role in the success of such a program. The major objective of this study was to determine the select ability of individual traits in the early generations of clones targeted for the potato chip processing industry. For this study, the cross between NDO1496-1 and A90359-7 was used. Progenies of this cross were selected and the seeds grown in 50 x 35cm planter flats. Seedlings were then transplanted individually to diameter pots after 5 weeks. 175 clones were randomly selected for inclusion in the next year and the process repeated consecutively for four generations, with each generation being selected for desired traits -skin color, tuber shape, maturity, eye depth, specific gravity, and size and shape uniformity. Tuber inter-generation correlation, of examined traits, were positive and significant (P<0.01) except for specific gravity which differed due to environmental factors. The percentage distribution of vine maturity revealed that only 6.2% of the late maturity clones would be lost if the entire high vigor class of the first generation was eliminated. Eye depth and round tuber shape are priority traits for selection followed by specific gravity and color chip as described in the study.
