JS-335 soybean: Madhya Pradesh kharif workhorse

JS-335 is a medium-duration kharif soybean (Glycine max) variety developed at Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Jabalpur and notified for general cultivation in 1994. It became the single most widely grown soybean variety of India through the 2000s and 2010s, occupying the bulk of the soybean acreage in Madhya Pradesh — the state that accounts for 45-50 percent of national soybean production — and remained the de facto industry benchmark even after newer varieties were released. It is part of the JS (Jabalpur Soybean) series that dominates the central Indian soybean tract.

Key characteristics

  • Breeder: JNKVV, Jabalpur (released through AICRP-Soybean, notified 1994)
  • Duration: 95-100 days
  • Yield: 25-30 q/ha rainfed irrigated; 20-25 q/ha rainfed
  • Plant type: semi-determinate, 70-80 cm tall, medium branching
  • Seed: yellow seed coat, light hilum, 100-seed weight 10-11 g
  • Oil content: 18-20 percent
  • Protein content: 40-42 percent
  • Reaction: moderately tolerant to bacterial pustule and frog-eye leaf spot; susceptible to yellow mosaic virus and girdle beetle

Cultivation

JS-335 is grown in the kharif season across Madhya Pradesh, Maharashtra (Vidarbha, Marathwada), Rajasthan (Kota, Jhalawar), Telangana (Adilabad-Nizamabad belt) and parts of Karnataka. Sowing is between 20 June and 5 July, after 75-100 mm of monsoon rain. Recommended seed rate is 60-75 kg/ha at 45 cm row × 5 cm plant spacing, with seed treatment of thiram + carbendazim at 3 g/kg followed by Rhizobium japonicum + PSB inoculant. NPK is applied at 20:60:40 kg/ha with 20 kg/ha sulphur as basal. The crop is largely rainfed in central India and matures in time to permit a rabi gram, wheat or mustard crop in the same field.

Pest and disease profile

The variety's main weakness is high susceptibility to soybean yellow mosaic virus (Soybean Yellow Mosaic Virus), transmitted by the whitefly Bemisia tabaci; in epidemic years yield losses on JS-335 reach 60-80 percent. It is also susceptible to girdle beetle (Obereopsis brevis) and stem fly (Melanagromyza sojae), which are managed with thiamethoxam 25 WG at 0.2 g/L or chlorantraniliprole 18.5 SC at 0.3 ml/L. Fungal pathogens of concern include Rhizoctonia aerial blight in heavy-rainfall pockets.

Adoption and use

Through the late 1990s and 2000s, JS-335 occupied 55-70 percent of soybean area in Madhya Pradesh and was the procurement standard for NAFED/state-agency PSS purchase. It is the parent or pedigree contributor of many subsequent JS varieties (JS 95-60, JS 97-52, JS 20-29, JS 20-34, JS 20-69). Newer YMV-resistant varieties such as JS 20-69, NRC-37 (Ahilya 4) and NRC-86 are gradually displacing JS-335 but it continues to be sown for its stable kharif yield and bold yellow seed preferred by the crushing industry.
