ABSTRACT
This study was conducted with the purpose of
developing QPM hybrids for Eastern Uttar Pradesh. In this effort 10 locally
adaptable maize inbreds were selected keeping in view of their past history as
they were good combiners and exhibited
good heterosis including for QPM traits when they were crossed with
adoptable QPM donors such as
CML141,CML193, DMRQPM58, HKI164-7-6, HKI162, CML169, CML176, CML161. About 80
hybrids were developed involving 8 QPM donors and 10 maize inbreds. Out of
these eighty hybrids 30 hybrids were selected for their evaluation your yield
and yield component in two environments i.e,
Rabi as well as Kharif seasons
during 2013-14 and 2014-15. In the present study as many six hybrids viz.,
HUZM185 X CML193, HUZM478 X CML193, V341 X CML141, V341 X HKI162, V341 X
DMRQPM58, V335 X CML161, CML141 X CML169 exhibited standard heterosis
ranging from 20 to 155 percent in
Kharif as well as Rabi Season.
