Short Note: Cleistogamy in Eucalyptus tereticornis Sm. and its Genetic Implications

In a provenance cum progeny trial comprising 13 provenances and 91 families of Eucalyptus tereticornis Sm. of Australian and Papua New Guinean (PNG) origin, laid out in India in 2002, cleistogamy was found in a family emanating from CSIRO seed lot no. 13418, (tree no. DS000141) Sirinumu Sogeri Plat, PNG. This trait appears to be under genetic control, and presumably results in obligate selfing. This may lead to inbreeding depression in this family.
