ICGV 87165, a high-yielding peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) germplasm line (Reg. no. GP-78, P1 594923) with multiple disease and insect resistance, was released in 1994 by the Plant Materials Identification Committee of the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) because of its resistance to rust (caused by Puccinia arachidis Speg.) and late leaf spot [caused by Phaeoisariopsis personata (Berk. & Curt.) Arx], and moderate resistance to bacterial wilt [caused by Pseudomonas solanacearum (Smith) Smith], leaf miner (Aproarema modicella Deventar), and tobacco caterpillar [Spodoptera litura (F.)]. ICGV 87165 is an interspecific derivative of a cross between P1 261942 (A. hypogaea subsp. fastigiata Waldron \sr.fastigiata) and A. cardenasii Krapov. & W.C. Gregory. It was developed through 14 generations of single plant and bulk selections for foliar diseases reaction and agronomically desirable characters (pod number and seed filling) from a cytologically unstable interspecific population of the above cross received from North Carolina State University, USA. The stabilized line was designated as CS 9. In 12 replicated yield trials conducted during 1983 and 1984 by the All India Coordinated Research Project on Oilseeds (AICOR-PO) at different locations in India, ICGV 87165 produced 39% greater pod yield than 'Kadiri 3'. The average pod yield of ICGV 87165 in these trials was 2.391 ha~'. In 2 yr of trials at three locations in Myanmar, it produced 104% greater pod yield than 'Japanese Small', which produced 0.451 ha~'. In similar trials conducted in the Republic of Guinea, ICGV 87165 outyielded the local cultivar by 29.4% with 1.98 t ha~'. In the Philippines, it gave a pod yield of 2.21 t ha~>, compared with 1.45 t ha~' for the local cultivar BPN Pn-9. In 13 trials conducted at seven Indian locations, ICGV 87165 was rated 3.11 for defoliation caused by late leaf spot, compared with a score of 6.89 for Kadiri 3 on a l-to-9 field rating scale (4). In 12 other trials conducted at six Indian locations for rust, ICGV 87165 scored 3.07, compared with 6.94 for Kadiri 3 on the same l-to-9 scale. ICGV 87165 maintained its resistant reaction to rust and late leaf spot over the local cultivars in the Republic of Guinea, Myanmar, Sudan, and northern Vietnam. At five locations in India for three seasons, ICGV 87165 showed 12.7% leaflet damage due to leaf miner, compared with damage of 38.0% for 'TMV 2'. At three locations in India, ICGV 87165 showed lower percentage of damage (19.9-69.5%) due to tobacco caterpillar than the local cultivars TMV 2, J 11, and ICGS 44 (31.2-99.2%). ICGV 87165 has also shown moderate resistance to bacterial wilt in Indonesia (3) and in Vietnam (1). ICGV 87165 has a Decumbent 3 growth habit (2), alternate branching, and small elliptic green leaves. It has 8 to 12 primary and 14 to 25 secondary branches. It matures in approximately 117 d during the rainy season in India. It has slightly reticulated pods with moderate ridges and beaks. The pods are...
