Development of a Novel Cultivar, ‘Yume Midori’, via the Use of Pollen Parent-specific DNA Markers in Chinese Chive

Abstract

A new Chinese chive (Allium ramosum L.) cultivar, ‘Yume Midori’, was obtained from a cross combination, ‘Koshu Nira’ × ‘Thunder Green Belt’, and it was developed for the first time by seedling selection of crossbreds using pollen parent-specific RAPD (Random Amplified Polymorphic DNA) markers. This new cultivar is estimated to have a sufficiently low crossing rate and exhibit excellent quality, such as high-yielding, broad leaf width, and long leaf sheath. Also, it is possible to improve the efficiency of shipping preparation. In addition, it is suitable for wintering to be harvested from winter to spring because of its shallow dormancy and high low-temperature elongation property, so even with summer harvesting from summer to autumn, the same yield and quality can be obtained compared with other varieties, making it suitable for annual production.
