Phenotypic Diversity of Alfalfa (medicago Sativa L.) Germplasm

Alfalfa (Medicago sativa L.) is one of the most important perennial forage crops on cultivated fields in the world. Agronomical interests for this crop are based on its numerous advantageous characteristics such as (1) high yield potential and suitable feeding value, (2) different methods of utilisation green mass, hay, silage, greenchop, briquette, pellets, etc., (3) favourable environmental i...

Phenotypic and Molecular Screening of Tomato Germplasm for Resistance to Tomato Yellow Leaf Curl Virus

Tomato yellow leaf curl virus (TYLCV) is a major tomato virus in tropical and subtropical regions. In this study, 134 accessions of Solanum lycopersicum and six accessions of Solanum peruvianum were assessed for resistance to an Iranian isolate of TYLCV. Plants were inoculated using whiteflies (Bemisia tabaci) and the reaction of plants was evaluated based on either disease symptoms or viral DN...

The Dahlia: An Early History

In 1934 Marshall Howe, of the New York Botanical Garden, compiled a list of Dahlia cultivars containing more than 14,000 names. This number represents an astonishing average of over 100 newly named cultivars during each of the 143 years since 1791, when dahlias were first brought into cultivation in the gardens of Spain following their arrival from Mexico. Today dahlias are among the most famil...
