Heterosis and combining ability studies for yield components and grain protein content in bread wheat Triticum aestivum (L.)

Wheat is the second most important food crop of the
country and contributes nearly one third of the total food
grain production [1]. The annual production of wheat in
India during 2010-11 was 85.93 m t [2] which was a
tremendous improvement over the production level four
decades back (12.57 m t in 1964) due to the rapid growth
in irrigated areas and popularization of high yielding
varieties. Rajasthan comprises NWPZ (North Western
Plain Zone) and Central Zone of wheat sharing about
10 per cent both in terms of area and production at the
national level. After the incorporation of dwarfing gene
‘Norin 10’ production was tremendously capitalized,
which brought food self-sufficiency and promoted the
build-up of buffer stocks in the country. However, to
meet the wheat production targeted at 100 mt by the
year 2030, sustained research efforts are needed to
keep the upward trend in wheat production well above
the population growth.
