Abstract
Popcorn (Zea mays var. everta) is an important cross
pollinated cereal crop of high economic value. For being tasty and
nutritious, always freshly popped for clients and served hot, it is very
popular. Looking to the importance the study conducted to assess
magnitude of heterosis and combining ability of 45 single cross
hybrids developed by half-diallel mating design involving 10 parents
and 1 standard check (Amber popcorn). The genetic diversity analysis
of parental inbred lines involved in the crosses was done by RAPD
molecular marker. The field experiment laid out in randomized block
design with three replications at Agronomy Farm, B. A. College of
Agriculture, Anand Agricultural University, Anand in rabi 2011-12.
The heterosis, combining ability and components of genetic variance
studied for 13 characters viz., days to 50% tasselling, days to 50%
