Genetic Diversity, Breeding and Utilization of Citrus Fruits

摘要

Citrus fruits are the third largest of the fruits grown in India with an estimated production of 2979.11 thousand m.t. from an area of 369.56 thousand ha. The country is the home of many citrus species, namely, Citrus inchangensis, C. latipes, C. macroptera, C. assamensis, C. aurantium, C. jambhiri, Citrus limonia, C. karna, C. pennivesiculata and C. maderaspatana. The diverse ecogeographical distribution and the occurrence of spontaneous mutations and natural hybridization have given rise to a widerange of variability in citrus and related genera. Genetic resources of citrus in India have been well reviewed (Singh and Chadha 1993; Chadha and Singh 1996).
