‘Barimash-2’ blackgram [Vigna mungo (L.) Hepper] (Reg. no. CV-196, PI 619180) was developed at the Pulses Research Centre (PRC), Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur - 1701, Bangladesh. The cultivar was released in Bangladesh in 1996 for stable and high yield with combined resistance to Bean yellow mosaic virus (BYMV) and Cercospora leaf spot (CLS) [caused by Cercospora cruenta Sacc. or Cercospora canescens Ell. & Mart.].

Barimash-2 was developed from the cross between two advanced lines BMA-2141 and BMA-2140 acquired from India. Single plant selections were made in the F₃. Fifty-six F₄ families were developed from this particular cross and evaluated in plant progeny rows in 1988-1989, and 34 F₄ families were selected and tested as F₅ families the following year. Ten F₅ families were retained as promising and were evaluated as F₆ lines. Days to maturity, reaction to disease, growth habit, podding intensity, and seed yield were given priority during selection. The 10 F₆ lines were evaluated in a replicated trial in 1990 to 1991 and seed was bulked. The bulked line was assigned the station identification number BMAX-90233. This line was evaluated in preliminary, advanced and regional yield trials during the winter seasons of 1991-1992, 1992-1993, and 1993-1994 at four locations (BARI, 1994).

Yield trials over 3 yr in different blackgram growing areas in three cropping seasons in Bangladesh showed that Barimash-2 averaged 1800 kg ha^-1, compared with 1200 kg ha^-1 for the ‘Barimash-1’ check (Afzal et al., 1999). Barimash-2 had a 30% yield advantage over Barimash-1 and a 60% advantage over the local check ‘Nowabganj’ and gave consistently higher yields throughout the trial (BARI, 1994). Because of its wide adaptability, the cultivar is recommended for three different mungbean growing seasons [Kharif - II (August–October), Kharif - I (February–May), and Late rabi (January–April)] and for all mungbean growing areas of Bangladesh.

Barimash-2 has an erect growth habit and attains a height of 33 to 35 cm. It flowers 35 to 40 d after emergence and reaches physiological maturity 70 to 75 d after emergence. Leaves are trifoliate, alternate, and green. Leaf pubescence is present. Petioles are short and purple-green. The corolla is yellowish-green. The raceme position is above the canopy. Mature pods are black and have hair. Seeds are drum-shaped and blackish. Barimash-2 has a 100-seed weight of about 4.2 g (Afzal et al., 1999).

Barimash-2 has resistance to BYMV and CLS. During initial evaluation, the families or lines were screened for combined resistance by the spreader row technique (Bakr, 1994). Highly susceptible lines for BYMV (BMN38) and CLS (B89) were planted after every five families or lines to create artificial disease pressure. Barimash-2 rated 0 on a rating scale of 0 to 5 for both diseases throughout its evaluation across locations (BARI, 1994).

Seeds of the Barimash-2 have 86.2% cotyledon content, and produce 71.8% head dhal (intact cotyledon after splitting) by the traditional method of dehulling. It takes about 33 min to cook and shows solid dispersion of 27.4%. Barimash-2 contains 22.9% protein and 47.0% carbohydrate (Afzal et al., 1999).

Breeder seed of Barimash-2 was distributed to the Bangladesh Agricultural Development Corporation (BADC) for production of Foundation and Certified seed. Breeder seed will be maintained by the Pulses Research Centre, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur - 1701, Bangladesh. U.S. Plant Variety Protection for Barimash-2 will not be sought. Small quantities of seed for research purposes may be obtained from the corresponding author for at least 5 yr from the date of this publication.
