Resour. 24(1): 96-153 (2011) Plant Germplasm Registration Notice 111 18. NRCGCS 86 (IC0582474; INGR10031), Groundnut (Arachis hypogaea) Germplasm, a source of Resistance to PBND (Peanut bud necrosis diseases), Stem Rot, Late Leaf Spot, Early Leaf Spot, Rust and Alternaria Leaf Blight SK Bera 1 , Vinod Kumar 3 , G Sunkad 2 , AL Rathnakumar 1 and T Radhakrishnan 1 1 Directorate of Groundnut Research, PB-05, Ivenagar Road, Junagadh-362 001, Gujarat 2 University of Agricultural Science, Raichur-584 102, Karnataka 3 National Research Centre for Litchi, Muzaffarpur-842 002, Bihar (E-mail: rathnakumar@nrcg.res.in) rose colour kernels. Kernels are small in size with hundred kernel mass of 32 g and contain 51.5% oil. The severity of foliar diseases in the genotype under field conditions are 2.0 for rust, 3.2 for early leaf spot and 3.8 for late leaf spot on a modified 9-point scale, and an incidence of 14.7% for peanut bud necrosis disease (PBND) and 8.3% for stem rot with almost immunity to Alternaria leaf blight disease has been recorded. The genotype has been identified as donor for multiple disease resistance in groundnut for peanut bud necrosis diseases, stem rot, late leaf spot, rust and Alternaria leaf blight. NRCGCS 86 (INGR10031; IC0582474) was selected from advanced generation of cross (CT 7-1 x SB 11) X A. correntina. The genotype was developed by pedigree selection from interspecific progenies developed at the Cytogenetics Section, Directorate of Groundnut Research, Junagadh, Gujarat. The plant has erect growth habit, produces 50% flowering in 26 days after sowing (DAS) and matures in 116 DAS during rainy season. The genotype produces an average pod yield of 84.5 g/m 2 with 73% shelling out turn. Pods are slightly constricted and moderately beaked as well as reticulated; mostly two seeded with 19.

Germplasm, Spanish Bunch Germplasm Accessions with Fresh Seed Dormancy AL Rathnakumar 1 , T Radhakrishnan 1 , SK Bera 1 , HB Lalwani 1 , Lata Raval 2 and Sugad Singh 1 1 Directorate of Groundnut Research, Junagadh-362 001, Gujarat 2 Junagadh Agricultural University, Junagadh-362 001, Gujarat (E-mail: rathnakumar@nrcg.res.in) Groundnut is an important oilseed crop of India grown in about 5.0 million ha during kharif and 1.0 million ha in rabi-summer seasons. The crop has four botanical varieties, Spanish bunch (Subspecies fastigiata var. vulgaris), Valencia (Subspecies fastigiata var. fastigiata), Virginia bunch and Virginia runner (Subspecies hypogaea var. hypogaea). The Spanish and Valencia genotypes have short life cycle and non-dormant seeds while those of Virginia types have long life cycle and dormant seeds. In India, Spanish types are predominantly grown in semi-arid regions where the growing seasons are short or are grown in multiple cropping sequences. Untimely rains either in kharif or in rabi-summer seasons prior to or immediately after harvest can cause seeds of Spanish and Valencia types to sprout in situ in the ground. In the semi-arid tropics, which account for 60% of the global production such situations are frequent and losses in yield and quality are substantial (Upadhyaya and Nigam, 1999). To avoid these losses during harvest it is essential to breed varieties having fresh seed dormancy up to 2-3 weeks duration. Before formulation of suitable breeding strategies, identification of sources of fresh seed dormancy are very essential. Reported sources of fresh seed dormancy especially among the Spanish bunch germplasm remain very few in literature.
