Abstract
The present investigation entitled “Heterosis and combining ability in wheat
(Triticum aestivum L.) was carried out at Regional Research Station, Anand
Agricultural University, Anand, Gujarat during rabi 2018-19.
The experimental material consisted of 67 genotypes, comprised of five lines,
ten testers, their 50 hybrids and two standard check varieties. The experimental
material was evaluated in Randomized Complete Block Design with three
replications. The observations were recorded on twelve different characters viz. days
to 50 % heading, days to maturity, plant height, number of effective tillers per plant,
length of main spike, number of spikelets per main spike, 100-grain weight, grain
yield per plant, biological yield per plant, harvest index, protein content and hectolitre
weight. The recorded data were subjected to analysis to assess per se performance,
heterotic effects (heterobeltiosis and standard heterosis), combining ability of parents
and their hybrids and gene effects.
