Canonical discriminant analysis; Coefficient of parentage; Genetic diversity index (GDI); Inter-simple squence repeat (ISSR); Morphometric analysis; RAPD

Eggplant (Solanum melongena), a vegetable that is cultivated worldwide, is of considerable importance to agriculture in China. We analyzed the diversity of this plant using inter-simple sequence repeat (ISSR) and RAPD procedures to subdivide 143 Chinese-cultivated eggplants based on coefficient of parentage, genetic diversity index (GDI) and canonical discriminant analysis. ISSR ... more

Chlorophyll accumulation; RAPD; Relative electrolyte leakage; SDS-PAGE

Cotton (Gossypium hirsutum) is an important cash crop, but high temperature during its growing season is one of the major factors that limit its productivity. This problem compels plant breeders to breed for heat tolerance, which can help to overcome this challenge. It is very important to make a comprehensive screening of heat-tolerant genotypes so that only the best are chosen ... more

Cultivar identification; Molecular markers; Pear; RAPD

Accurate and reliable cultivar identification of crop species is essential to guarantee plant material identity for purposes of registration, cultivar protection and production. To facilitate identification of plant cultivars, we developed a novel strategy for efficient recording of DNA molecular fingerprints in genotyped plant individuals. These fingerprints can be used as efficient ... more

Genetic diversity; Mycelial compatibility groups; RAPD; Sclerotinia sclerotiorum; White mold

The genetic variability of 40 Sclerotinia sclerotiorum isolates from various fields widely distributed throughout Brazil and different host crops was analyzed using RAPD markers and mycelial compatibility groupings (MCGs). The isolates were characterized using 16 random primers of the OPERON series, which produced 121 DNA fragments. UPGMA cluster analysis using Jaccard’s genetic ... more

Punica granatum; RAPD; Wild pomegranate

The pomegranate has been used traditionally in Coruh Valley in Turkey for a long time; fruits are harvested from wild, semi-domesticated and cultivated trees. In the valley, it oc­curs in general along with olive trees. We sampled 23 wild-grown pomegranate genotypes sampled from different parts of Coruh Valley and compared them using RAPD primers to determine ge­netic variability. Eighty- ... more

Cacao; Exoenzymes; Genetic variability; RAPD; Witches’ broom

We evaluated the genetic and physiological variability of Moniliophthora perniciosa obtained from healthy and diseased branches of cacao (Theobroma cacao) plants. The diversity of the isolates was evaluated by RAPD technique and by studies of virulence and exoenzyme production. The genetic variability of endophytic and pathogenic M. perniciosa was evaluated in ... more

Brassica napus seeds; Genomic DNA; Lipids; PCR; RAPD; Restriction analysis

A simple protocol for obtaining pure, restrictable and amplifiable megabase genomic DNA from oil-free seed residue of Brassica napus, an important oil seed plant, has been developed. Oil from the dry seeds was completely recovered in an organic solvent and quantified gravimetrically followed by processing of the residual biomass (defatted seed residue) for genomic DNA isolation. ... more

Dalbergia sissoo Roxb.; Genetic differentiation; Genetic diversity; RAPD

Dalbergia sissoo, a wind-dispersed tropical tree, is one of the most preferred timber tree species of South Asia. Genetic diversity and differentiation among natural populations of D. sissoo were examined for the first time. We found a relatively high level of genetic diversity in D. sissoo, both at the species level (percentage of polymorphic bands = 89.11%; H ... more

Interspecific hybridization; Passiflora L.; Paternity test; RAPD

Several interspecific Passiflora hybrids are produced in the northern hemisphere for the ornamental plant market. In Brazil, production of passion flower hybrids is limited to the introgression of genes into the main cultivated species, yellow passion fruit, to be used as rootstocks. Confirmation of hybridization in the initial developmental stage is important for breeding ... more

C. equisetifolia subsp incana; Casuarina equisetifolia subsp equisetifolia; Genetic diversity; Molecular marker; Northern coast of Senegal; RAPD

The genetic variation of 70 individual samples of Ca­suarina equisetifolia (L. Johnson) subsp equisetifolia and C. equiseti­folia subsp incana growing along the northern coast of Senegal was analyzed with RAPD markers. Of the 160 primers tested, five were chosen; they generated 1396 reproducible bands and 61 polymorphic bands that were scored. This ... more
