Abstract/Description: | Castor genetic resources Germplasm augmentation: Two accessions collected from Sundarban, West Bengal, 56 accessions received from NBPGR, New Delhi and 215 accessions supplied by AICRP (Castor) Mandor centre were added to the repository. Characterization and evaluation: Seventy two fresh collections were characterized for 23 morphological descriptors. The same were evaluated for 19 quantitative traits under rainfed condition. Considerable variation was observed for different quantitative traits. Supply of germplasm: Total 990 accessions were supplied to various centres for multilocation yield evaluation and screening against diseases and insect pests. In addition, 178 accessions were supplied for research purpose to various castor researchers in the country. Germplasm multiplication and documentation: A total of 3144 accessions including 241 accessions supplied by NBPGR, New Delhi, 165 of castor core and 2738 accessions of DOR castor repository were multiplied. Passport information and data on morphological and quantitative traits of 72 fresh accessions were documented. Castor germplasm field day: A castor germplasm field day was conducted on 4 November 2011. Twenty five castor researchers participated in the field day. On-farm performance of 3216 castor accessions, which are resistant to wilt, root rot, nematode, jassids, whitefly and leafminer, multiple resistance to wilt, root rot and nematode, tolerance to Botrytis; non-VP-1 pistillate selections, distinct morphotypes, fresh collections and accessions possessing promising yield traits, was demonstrated during the field day. Castor core: Castor core comprising 165 accessions was characterized for 23 morphological descriptors and evaluated for 15 quantitative traits. Seeds of 165 accessions were multiplied. Pistillate selections derived from germplasm: Forty four derivatives of nine non-TSP-10R pistillate selections showed stable pistillatness up to higher order spikes. These were maintained and multiplied. Sources of resistance against diseases and insect pests Wilt: Resistance to wilt was confirmed in seven accessions viz., RG1221, RG1354, RG2430, RG 3016, RG 2800, RG 3093 and RG 3105 using root-dip inoculation method. Nineteen accessions were found free from wilt in wilt sick plot while 10 had less than 20% infection. Botrytis grey mold: Ten accessions (RG 26, RG 1139, RG 1759, RG 1963, RG 2759, RG 2810, RG 3216, RG 3309, RG 3311, RG 3383) exhibited resistant reaction (<10% capsule infection) against grey mold under artificial epiphytotic conditions in field. Nematode: Thirty accessions exhibited moderate resistance (11-20 average number of egg masses/root system) against nematode under artificial inoculation conditions in glasshouse. Leafhopper: Four accessions viz., RG 2661, RG 2468, RG 1445, and RG 3067 confirmed resistant reaction (0 hopper burn grade on 0-4 scale) against leafhopper in the third consecutive year while three accessions (RG 2499, RG 565, RG 220) showed moderate resistance reaction. Capsule borer: One accession RG 2786 exhibited moderate resistance to capsule borer. |
