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

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