HETEROSIS IN CMS/GMS BASED PIGEONPEA [CAJANUS CAJAN (L.) MILL SP.,] HYBRIDS

Twenty seven early maturing pigeonpea experimental hybrids resulting from L x T analysis
were studied to know the magnitude of heterosis in pigeonpea. Heterosis over standard parent
for single plant yield varied from –25.0%(CORG 990047 A x ICPL 87) to 325%(MS CO 5 x PA
128). For per se performance single plant yield varied from 15 g(CORG 990047 Ax ICPL 87) to
85.0 g (MS CO5 x PA 128). While considering about mean performance, sca effects and standard
heterosis the promising hybrids namely CORG 990047 A x APK 1 which was found to be superior
for days to 50% flowering, days to maturity, plant height(cm), number of pods/plant, seed protein
content and single plant yield; MS CO5 x ICPL 83027 had significantly higher mean performance,
significant sca effects and standard heterosis for plant height, number of branches/plant, number
of pods/plant, number of seeds/pod and single plant yield.
