fertile hybrids, the promising combinations will be selected to produce hybrid seed again for confirming their fertility restoration and agronomic performance. KB Saxena and K Madhavi Latha Milestone 5A.1.1.2: At least five high yielding hybrids each in early and medium maturity duration identified for multi-location testing (KBS/KML, 2007) A total of 405 new experimental hybrids were evaluated for their agronomic performance in 20 station trials at Patancheru. Due to frequent rains during early growth stages, the short-duration experiments were damaged by intermittent water-logging and phytophthora blight and eight trials were abandoned. In the remaining four trials, the yield levels were low when compared with the previous season. Among these hybrids, ICPH 3538 (2014 kg ha -1 ) was found to be the best with 92% superiority over the control ICPL 88034 (1027 kg ha -1 ). The other promising hybrid in this group was ICPH 3548 (1832 kg ha -1 , 78% superiority). The data from medium-duration hybrid trials are awaited. KB Saxena and K Madhavi Latha Milestone 5A.1.1.3: At least five pigeonpea hybrids identified for on-farm testing (KBS/KML, 2008) Based on the performance of hybrids in multilocation trials conducted in 2005 rainy season and the availability of seed, one short-duration hybrid (ICPH 2438) and one medium-duration hybrid (ICPH 2671) were evaluated at 20−25 farmers’ fields in Maharashtra, Karnataka and Andhra Pradesh by cooperating NARS partners and seed companies. The data are awaited. In order to identify new hybrids for on-farm testing in 2007 rainy season, 24 short-duration hybrids are being evaluated at 10 locations. Similarly, in the medium-duration group 32 hybrids are being evaluated at 15 locations. The parental seeds of these hybrids are being multiplied either in isolation or under insect-proof cages. KB Saxena and K Madhavi Latha Milestones 5A.1.1.4: Elite pigeonpea hybrids evaluated for their resistance to major insects and diseases (2009) Four hundred and eighty-one hybrids and their parents were evaluated for wilt and SM resistance under artificial epiphytotic conditions following standard field evaluation techniques. Wilt-susceptible ICP 2376 and SMsusceptible 8863 were sown after every 10 test entries as infector-cum-indicator rows. Of these, 11 hybrids, ICPHs 2324, 2373, 3183 (ICPL 20106), 3224 (ICPL 87051), 3363, 3450, 3476, 3477, ICPR 2337 (ICPL 20106), ICPLs 87119, ICPL 20110, were found asymptomatic, while 21 were found resistant with
Milestone 5A.2.1.2: At least six promising maintainers of A 4 cytoplasm improved for agronomic traits (seed and pod size and disease resistance) through backcrossing (KBS/KML, 2009) In any dynamic hybrid breeding program the genetic enhancement of female parents for desired agronomic traits is essential to develop promising hybrid combinations. To increase the pod size of promising A-lines, ICPA 2039 and ICPA 2089 were crossed with a white seeded variety ‘Kanchan’. Similarly, crosses are being initiated to incorporate sterility mosaic and wilt resistance in ICPA 2044 and ICPA 2045. KB Saxena and K Madhavi Latha Output target 5A.3: Pigeonpea hybrid parents (25−30 A-lines and 50−55 R-lines) characterized for important agronomic traits and molecular diversity (2009) Activity 5A.3.1:Assessing the agronomic and molecular diversity of pigeonpea hybrid parental lines Milestone 5A.3.1.1: A/B- and R- lines characterized for important agronomic traits (KBS/KML/HCS/SP, 2008) During the 2006 rainy season, 26 maintainer lines and 22 restorer lines were evaluated in separate replicated trials at Patancheru. The data are being compiled on a number of qualitative and quantitative traits. We propose to repeat this trial in 2007 rainy season also. This information will be shared with the germplasm unit and also will be used for registration and selection of hybrid parents in the future. KB Saxena, K Madhavi Latha, HC Sharma and S Pande Relative susceptibility of maintainer and restorer lines to Helicoverpa armiger: Fifteen restorers and 13 maintainer lines along with resistant (ICPL 187-1, ICPL 332) and susceptible (ICPL 87 and ICPL 87119) checks were evaluated for resistance to the pod borer, H. armigera. There were three replications in a randomized complete block design for each set. Data were recorded on pod damage and overall resistance scores at maturity. The overall resistance scores ranged from 4.5 to 9.0. The maintainer lines ICPB 2032, ICPB 2049, ICPB 2050, and ICPB 2051 showed a damage rating of 5.5 to 6.0 compared to 8.2 in ICPL 87 and 4.5 in ICPL 332. Percentage pod damage ranged from 75.7 to 86.4%. Most of the lines (except ICPB 2032, ICPB 2043, ICPB 2046, ICPB 2046, and ICPB 2048) were highly susceptible to wilt (over 80% mortality). Among the restorer lines, the genotypes ICPR 2913, ICPR 2920, ICPR 2922 showed a damage rating of 4.7 to 6.0 compared to 4.5 in ICPL 332 and 8.2 in ICPL 87. Pod damage was 56.6 to 70.0% in ICPR 2336 and ICPR 2904 compared to 64.8% in ICPL 332 and 86.0% in ICPL 87. The lines ICPR 2904, ICPR 2905, and ICPL 187-1 showed high susceptibility to wilt (>80% plant mortality) compared to 7.8% in improved version of ICPL 332 and 8.5% in ICPL 87. HC Sharma and KB Saxena Milestone 5A.3.1.2: Available male sterile (A/B) and fertility restorer (R) lines characterized using molecular markers (RKV/KML/KBS/DAH, 2009) Output Target 5A.4: Seed production technology for pigeonpea hybrids and their parents improved (2009) Activity 5A.4.1: Developing an efficient seed production technology for pigeonpea hybrids and their parents. Milestone 5A.4.1.1: Improved seed production technology for pigeonpea hybrids and their parents developed (KBS/KML, 2009) Hybrid pigeonpea technology is new and the efficiency of commercial hybrid production depends on the improved seed production technology. To reduce the cost of seed production of A-lines, an experiment was carried out by sowing ICPA 2048 at three spacings (75 × 30, 75 × 100, 75 × 150 cm). The results are awaited.
