Abstract

The seguin chestnut, commonly called Maoli in China, is one of the three chestnut species (C. mollissima, C. seguinii, and C. henryi) native to southeastern and central China. Seguine is a valuable germplasm resource for horticultural traits such as precocity, everbearing, high yield, blight resistance, and dwarfism. A recurrent selection breeding program was initiated in 1989. Since seedlings flowered as early as 3 weeks, selections were made annually for seven generations. Improvement in precocity, everbearing, yield, quality, blight resistance, and dwarfism is sought. The everbearing and high-yielding plants should provide an abundant source of food for wildlife on a continuing yearly basis. Incorporation of the precocious and dwarf traits into commercial chestnut species can enhance the development of high-density chestnut production.
