    Abstract

    An investigation was carried out during kharif (monsoon) season of 2010-11 at ICRISAT, Patancheru, Hyderabad, to study (i) relative mid-parent heterosis, heterobeltirosis, and standard heterosis in medium duration disease resistant pigeonpea hybrids, (ii) inbreeding depression from F1 to F2 generations for important economic traits, and (iii) genetics of fertility restoration. A total of 22 hybrids were synthesized by hand pollinating five CMS-lines with 14 restorers during 2009 kharif season. The F1 plants of each hybrid were selfed to obtain F2 seeds. Genetics of fertility restoration was studied by using F1, F2, and BC1F1 data in four crosses...
