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.
