‘Idlib-2’ lentil (Lens culinaris Medik.) (Reg. no. CV-14, PI 631396) was developed at the International Center for Agricultural Research in the Dry Areas (ICARDA), Aleppo, Syria, and released in 2000 by the Directorate of Agriculture and Scientific Research, Ministry of Agriculture and Agrarian Reform for commercial cultivation in Syria. It is a high yielding red cotyledon lentil cultivar with lodging resistance and resistance to vascular wilt [caused by Fusarium oxysporum f. sp. lentis (Vasudeva & Srinavasan) Gordon.].

Idlib-2 was developed through single-plant selection from a Jordanian landrace, 74TA14. It was introduced at ICARDA in 1977 and is designated as ILL 16. Considerable heterogeneity was observed among plants, and a single-plant selection (81S 15) was made at ICARDA in 1981. After testing in a nonreplicated preliminary screening nursery and replicated preliminary and advanced yield trials between 1983 and 1985, it was entered into the international testing program in 1986 as one of the promising lines in the small-seeded lentil nursery. The line was entered into the Lentil Germplasm Catalog as accession ILL 5883.

The Syrian national program identified ILL 5883 as a high-yielding line from the Lentil International Nursery (small seed) supplied by ICARDA. It was tested in six contrasting sites in Syria from 1986–1987 to 1988–1989. On average, ILL 5883 gave 1625 kg ha^-1 seed yield compared to 1286 kg ha^-1 for the local check, Hurani representing an increase of 26.3%. The line was evaluated under on-farm trials from 1986–1987 to 1996–1997 at 14 sites across the lentil-growing areas in Syria. Averaged over 154 on-farm trials, ILL 5883 produced a mean seed yield of 1365 kg ha^-1, compared to 1232 kg ha^-1 for the check, Hurani. Lentil straw is an important animal feed in Syria. The cultivar produced an average straw yield of 3379 kg ha^-1.

Vascular wilt is a devastating disease of lentil in many countries. Yield losses up to 72% have been reported in Syria (Bayaa et al., 1986). ILL 5883 is resistant to vascular wilt as evidenced from plastic house screening in trays (Bayaa and Erskine, 1990) and in wilt-sick plot at Tel Hadya, ICARDA. In screening trials in wilt-sick fields from 1993–1994 to 2000–2001, ILL 5883 had <5% wilted plants compared to up to 40% wilted plants in the local check, Hurani. In on-farm trials over the years across Syria, 2.7% wilted plants have been observed in ILL 5883.

Hand harvest is a major constraint for lentil production in Syria because of the high cost of manual labor. Local lentil cultivars are susceptible to lodging and not suitable for machine harvest. ILL 5883 has a semierect growth habit with strong stems, thus providing lodging resistance and is suitable for mechanical harvesting. It forms its lowest pod at about 15 cm above soil level, which reduces harvest losses. Plants of ILL 5883 are medium statured (35 cm) with more basal primary branches compared to local cultivars. Leaves are dark green with medium-size leaflets and long tendrils. Intermingling of tendrils keeps the canopy upright at maturity, thus facilitating mechanical harvesting.

ILL 5883 flowers in 115 d and attains physiological maturity in 152 d, which is similar to local cultivars. Most leaflets are retained at 100% maturity leading to higher straw yields. It has bright red cotyledons and reddish testa color without pattern. It has a 100-seed weight of 4.0 g, compared with 3.0 g or less for the local cultivars. Its dehulled seed has a protein content of 263 mg g^-1 compared with 250 mg g^-1 protein in Hurani. It takes 37 min to cook. Straw of ILL 5883 contains 69 mg g^-1 protein, 493 mg g^-1 dry organic matter digestibility, and 569 mg g^-1 fiber.

Seed of Idlib-2 is maintained by the Germplasm Program of ICARDA at Aleppo, Syria, and is available in small quantities on written request. Plant variety protection will not be sought for Idlib-2.
