Registration of ICGV 86699 peanut germplasm line with multiple disease and insect resistance uri icon

abstract

  • This high-yielding elite groundnut (Arachis hypogaea subsp. hypogaea var. hypogaea) germplasm line, released in 1994 and developed from a single-plant selection made in CS29 (A. batizocoi/A. duranensis//A. hypogaea cv. NC2), is noted for its resistance to Puccinia arachidis and Sclerotium rolfsii (Corticium rolfsii) and its tolerance of Phaeoisariopsis personata (Mycosphaerella berkeleyi), Cercospora arachidicola (Mycosphaerella arachidis), peanut bud necrosis virus and peanut mottle potyvirus. It also suffers less damage due to Empoasca kerri and Spodoptera litura than control cultivars under field conditions. In 20 replicated trials conducted in different locations in India during 1987-90, ICGV86699 produced an average pod yield of 1.25 t/ha, 47% greater than Kadiri 3. Similarly, in Myanmar its pod yield averaged 1.42 t/ha, 100% greater than the local cultivar Sinpadetha 2. ICGV86699 has a Decumbent 3 growth habit, alternate branching and medium-sized elliptic green leaves. It matures in ~118 days in the rainy season in India. Pods are mostly 2-seeded with average meat content of 60%. Seeds are red, weigh 38 g per 100 seeds and contain 48% oil and 24% protein
