Final version of Tropical Legumes II Project Report for Phase 1 - icrisat

Generation of new breeding lines
At one partner center the facilities for crossing programs to generate new breeding populations were
strengthened; this was made possible by erecting hybridization facilities. In the state of Karnataka, such
facilities were made at Agricultural Research Station (ARS), Chintamani to expand the breeding activities.
In Tamil Nadu, the breeding activities were conducted at research stations located at Tindivanam and
Coimbatore. During the project period, 88 fresh crosses were made and segregating populations (F2-
F5) derived from 80 crosses were studied and selections were made.
In Karnataka, at ARS-Chintamani, UAS-Bangalore during the project period, 32 fresh crosses were
completed and segregating generations (F2-F7) derived from 150 crosses were studied and selections
made. At ARS-Bagalkot, UAS, Dharwad 71 fresh crosses were made and six segregating populations
(F2-F5) were studied during the project period. At Main Agricultural Research Station (MARS), UAS-
Raichur crosses were made involving 17 parents with an objective to develop varieties with foliar
disease resistance and segregating populations from 23 cross combinations were studied. The fresh
crosses made and breeding material handled are summarized in Table 2-18.

Capacity building
Ms D Shoba has completed her doctoral studies at TNAU, Coimbatore, and submitted her dissertation
titled “Identification of molecular markers for resistance to rust (Puccinia arachidis) and late leaf spot
(Phaeoisariopsis personata) in groundnut (Arachis hypogaea L.)”. The foliar disease screening facilities
developed at Coimbatore under this project were used by the student for phenotyping the parents
and mapping populations. Mr Sreenivasa Raghavan from UAS, Raichur completed his MSc research
work under the project. Mr. K Girishkumar from TNAU, Coimbatore, Messrs. H V Krishne Gowda,
M Manjunatha and Manjunatha Bhanuvally from UAS-Bangalore and Messrs, F C Nadaf and Mirza
Sajiulla Baig from UAS-Raichur received hands-on training on groundnut breeding technologies and
production aspects and on aspects of virus screening at ICRISAT. Two scientists Drs. M Vaidyalingan and
N Manivannan from TNAU, Coimbatore were trained on the use of molecular markers in groundnut
breeding at ICRISAT.
