Description The present investigations were carried out to derive information on heterosis, combining ability, stability and some quality parameters in a series of CGMS-based pigeonpea hybrids. Also, it was aimed to study the genetics of fertility restoration and stability of the male-sterile lines of pigeonpea. A line x tester mating design was used to develop F1 hybrids using three CGMS lines ICPA 2043, ICPA 2047 and ICPA 2092 developed at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru (Andhra Pradesh). All three A-lines were derived from Cajanus cajanifolius (A4) cytoplasm. The testers comprised of 13 inbred lines obtained from ICRISAT; 10 lines from Agricultural Research Station, Badnapur, M.A.U., Parbhani, five lines from MPKV Rahuri; and six lines from Pulses Research Unit, PDKV, Akola. All the materials were evaluated at Patancheru, Parbhani, Latur and Badnapur. All the cross combinations were made during kharif 2008 in a line × tester mating design. The hybrids and parents were evaluated in α-lattice design with two replications. Observations were recorded on five competitive plants on days to 50% flowering, days to maturity, plant height (cm), number of primary branches plant-1, number of secondary branches plant-1, total number of pods plant-1, seeds pod-1, pod weight (g), 100........
