Broccoli (Brassica oleracea var. italica) is an important commercial vegetable crop. As part of an efficient pollination system, cytoplasmic male sterility (CMS) has been widely used for broccoli hybrid production. Identifying the original sources of CMS in broccoli accessions has become an important part of broccoli breeding. In this study, the diversity of the CMS sources of 39 broccoli acces...

in order to study the response of five watermelon accessions (tn.93.765, tn.93.469, tn.93.485, tn.93.425 and tn.93.330) to drought stress an experiment was conducted as factorial experiment in randomized completely block design with three replications. this research were investigated in hydroponic system with four levels of osmotic potential induced by poly ethylene glycol 6000 (peg) including ...

Microsporogenesis was analyzed in five accessions of Brachiaria dictyoneura presenting x = 6 as the basic chromosome number. All accessions were tetraploid (2n = 4x = 24) with chromosome pairing in bi-, tri-, and quadrivalents. The recorded meiotic abnormalities were those typical of polyploids, including precocious chromosome migration to the poles, laggard chromosomes, and micronucleus format...

Sequence-related amplified polymorphism (SRAP) markers were used to assess the genetic diversity among a collection of 52 sesame accessions representing different geographical environments, including eight Saudi landraces. A combination of seventeen primers generated a high number of alleles (365) with 100% polymorphism. The polymorphic information content (PIC) and primer discrimination power ...

A total of 324 Japanese rice accessions, including landrace, improved, and weedy types were used to 1) investigate genetic variations in blast resistance to standard differential isolates, and 2) across the genome using polymorphism data on 64 SSR markers. From the polymorphism data, the accessions were classified into two clusters,. Accessions from irrigated lowland areas were included mainly ...

Food security is a global concern amongst scientists, researchers and policy makers. No country is self-sufficient to address food security issues independently as almost all countries are inter-dependent for availability of plant genetic resources (PGR) in their national crop improvement programmes. Consultative Group of International Agricultural Research (CGIAR; in short CG) centres play an ...

We conducted SSR analyses of 59 accessions, including 29 traditional plum (Prunus domestica), 24 sweet cherry (Prunus avium), and 1 sour cherry (Prunus cerasus) selected from East Anatolian gene sources and 3 plum and 2 cherry reference accessions for molecular characterization and investigation of genetic relationships. Eight SSR loci [1 developed from the apricot (UDAp-404), 4 from the peach ...

The requirement for vernalization, a need for prolonged cold to trigger flowering, aligns reproductive development with favorable spring conditions. In Arabidopsis thaliana vernalization depends on the cold-induced epigenetic silencing of the floral repressor locus FLC. Extensive natural variation in vernalization response is associated with A. thaliana accessions collected from different geogr...

Genetic diversity analysis is a fundamental work for effective management and utilization of plant germplasm. Brassica juncea an economically important crop, including both oilseed vegetable types. In the present study, total 99 accessions Brassicaceae family, 84 mustard (50 34 types) in China 15 other were evaluated their genetic using nuclear mitochondrial molecular markers. All 18 simple seq...

The panicle architecture is a critical determinant of the reproductive success rice plants and has direct impact on grain production. In this study, we evaluated genetic variation parameters in fifteen genotypes compared them with five commonly grown cultivars study area to assess their potential for crop improvement initiatives. selection 15 was based specific criteria, including diversity ori...
