Species and/or cultivar differences are also observed in other starch properties and in the properties of isolated amylose and amylopectin. To illustrate, purified amylose samples have been shown to differ in (3-amylolysis limit and average DP.64,67,124 Purified amylopectin samples have also been shown to differ in (3-amylolysis limit, average length of unit chains and viscosity.64,66 67 124,125 Campbell et al.121 observed a range of amylose content from 22.5% to 28.1% in 26 maize inbreds selected for maturity, kernel characteristics and pedigree. Starches from these non-mutant genotypes also differed in thermal properties (DSC), paste viscosities and gel strengths. 

The pedigree method has been used since the rediscovery of Mendel s laws and has led to many successful soybean cultivars. In the pedigree method, the ancestral lineage of each line tracing back to individual plants is recorded. Thus, care must be taken to keep accurate records so each selection can be traced back to the original hybridization. The size of the population is a subject of considerable discussion among breeders... 

The pedigree method has been used to develop many soybean cultivars. This method allows the breeder to discard inferior phenotype material early in the inbreeding process, allows the breeder to minimize the relationship among retained lines, and provides phenotypic observations over several generations in different environments. However, this method requires considerable land, labor, and other resources as well as extensive record keeping, usually requires an experienced breeder to make... 

Oro was Canada s first B. napus low-erucic acid rapeseed cultivar, developed by Agriculture and Agri-Food Canada, Saskatoon, and released in 1968 (Stefansson and Downey 1995). Oro was developed by pedigree selection in the progeny from the cross of Nugget x Liho. It had an erucic acid concentration of less than 5% and a high glucosinolate concentration of over 150 pmol/g air-dried, oil-free meal. 

Breeding for improved seed yield is the main breeding objective for HEAR cultivar development programs. Eor B. napus HEAR cultivars, this has involved, successively, selection within OPP landraces, crosses of OPPs and pedigree selection of derived families and hybrids (McVetty et al., 2009). 

Commercial flax cultivars are pure-lines developed via hybridization of inbred lines with complementary traits followed by pedigree selection of recombinant lines from segregating progeny (Culbertson, 1954 Kenaschuk, 1975). The aim is to obtain a pure-line cultivar that combines all the goies and meets the breeding objectives.
