JLS 9

JLS 9 is a linseed variety from Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Jabalpur — the "JLS" prefix marks the Jabalpur linseed selection series — recommended for Madhya Pradesh, which is India's largest linseed state. It is a medium-duration line, roughly 120–130 days, grown both as a rainfed sole crop on the state's black soils and in rice-fallow (utera) situations. Its wilt and rust reaction is best treated as moderate tolerance rather than full resistance. This record does not restate a precise release year or yield-trial figure for JLS 9, because those were not confirmed against a single primary JNKVV source; it is presented as a state-recommended Madhya Pradesh variety in cultivation. For central India, the JLS series as a whole — including newer numbers such as JLS 73 — is the mainstream local choice.

SeasonRabi

• Sowing timeMid-October to mid-November as a line crop; late September to October for a utera crop into standing paddy
• Seed rate25–30 kg/ha (10–12 kg/acre) for line sowing; 35–40 kg/ha for broadcast and rice-fallow (utera) sowing
• FertilizerRainfed: about 30–40 kg N and 20 kg P2O5 per hectare, all basal. Utera crop: a low basal dose only (about 10–20 kg N, 20 kg P2O5, 10 kg K2O per hectare)
• HarvestingHarvest at about 120–130 days when the capsules are brown and dry but still closed; cure in a stack, then thresh gently.

Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.

• Madhya Pradesh

• T-397

  The old national check variety, released around 1960 — a small brown-seeded, spreading type still grown across Bundelkhand, Bihar, Assam, Madhya Pradesh and Rajasthan for its wide adaptation and tolerance to rust, wilt and drought.

• Neelam

  A variety carried in state recommendations for its combined rust and wilt resistance, grown mainly in the central and eastern tracts. Treat the specific release centre and year as not independently confirmed for this record — its standing rests on the disease-resistance trait it is listed for.

• Shekhar (KL-223)

  A high-yielding variety from CSAUAT, Kanpur, widely grown in Uttar Pradesh — including in black-gram–linseed and rice-fallow systems — and moderately resistant to rust and Alternaria blight.

• JLS 73

  A newer Jabalpur (RARS Sagar) line developed under the AICRP on Linseed, noted for a very high alpha-linolenic (omega-3) fraction in its oil — of interest where the crop is grown for the health-food market rather than only for total oil.

• RLC 153

  An IGKV, Raipur release for Chhattisgarh, bred for the state's rice-fallow and utera situations. Treat its exact duration, yield and disease figures as not independently confirmed for this record — its fit is the eastern relay system it was developed for.

• Kiran

  A variety carried in recommendations for rainfed situations, with a bolder seed than T-397. Treat the specific release centre, year and yield as not independently confirmed for this record.
