“…The average inbreeding of the clones adapted to the southeastern United States is 0.054 due to the reported inbreeding in three Alabama releases ('AU Roadside', 'Homeside', and 'Purple') and one Texas release ('Morris'). Of these four clones, three ('AU Roadside', 'Homeside', and 'Morris') have reported parentage that appears mistaken (Byrne and Littleton, 1988). Thus, the actual amount of inbreeding would likely be lower than that based on reported parentage.…”

The mean inbreeding and coancestry coefficients of Japanese-type plums grown in California and the southeastern United States were one-half or less of those calculated for peach. The three most important founding clones for the major California cultivars were ‘Santa Rosa’, ‘Eldorado’, and ‘Gaviota’; for the plums of the southeastern United States they were ‘Methley’, ‘Santa Rosa’, and ‘Mariposa’. The species background of both groups of plums was ≈50% P. salicina, although the sources of P. salicina differed between groups. For the California cultivars, the other half was composed of P. simonii and P. americana, whereas, for the southeastern group, the major contributing species was P. cerasifera, with lesser contributions from P. simonii, P. americana, P. angustifolia, and P. munsoniana.

“…Biochemical-and DNA-based markers enable the identification and description of cultivars and parental lines of hybrids, assessing the genetic purity of seed, diversity in agricultural cultivars and their wild variants, phylogenetic analysis, and pinpointing the origin of the germplasm. The identification of isoenzymes was the first tool for genetic analysis [124]. This method was used by Tai-Young [125] to identify cultivars and validate the purity of radish seeds.…”

In tropical, subtropical, and temperate climates, radish (Raphanus sativus L.) is a popular root vegetable. Radish diversity is intense from the eastern Mediterranean to the Caspian Sea. Many radish varieties have varied leaf morphology, root color, size, shape, flavor, vernalization requirements, and maturity times. Early radish variants were long and tapered rather than cylindrical, bulbous, elliptic, or spherical. For black Spanish radish, European-cultivated variety, and Asian-cultivated radish, three separate domestication processes occurred. The original radishes were black, followed by white in the 1500s then red and round in the 1700s. These are R. sativus L. var. radicula (sativus) or R. sativus L. var. niger radishes. Because of protogyny, self-incompatibility, open architecture, and biennial bolting, radish crosses readily. The fundamental methods for using heterotic breeding potential are SI, CMS, and doubled haploids (DH). This chapter discusses the various breeding strategies like inbred line development by the use of self-incompatibility, hybrid development by using male sterility system, population improvement, mutation breeding, haploid breeding, breeding strategies for biotic and abiotic stresses, QTL mapping, and genome wide and genomic tool in radish. Rapid developments in our understanding of advanced biotechnology technologies will increase our ability to identify cultivars and parental lines, check seed genetic purity, analyze phylogenetic links and genetic diversity, and add specific transgenic traits.

“…MDH has two zones of activity in Prunus: the faster-m igrating zone (M D H-1 ) rep resents the cytosolic isozymes, with the slower zone (MDH-2) consisting of the mitochon drial forms (1). Both are dimeric in Prunus and many other plants (1,4,6 ). Although plum and apricot have alleles in common, apricot has an allele for each locus that is not present in plum (Fig.…”

A series of diploid plum (Prunus salicina Lindl. and hybrids), apricot (P. armeniaca L.), and plum × apricot (plumcot) clones were surveyed for six enzyme systems to identify a biochemical marker system for plumcots. Peroxidase (EC 1.11,1.7) was the best marker for identifying plum × apricot hybrids. The other systems contained plum or apricot specific alleles useful in verifying hybrid parentage of first or later generation derivatives.
