Registration of ‘Barimung‐4’ Mungbean

Abstract

‘Barimung‐4’ mungbean [Vigna radiata (L.) Wilczek] (Reg. no. CV‐181, Grif 14472, PI 614898) 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 mungbean yellow mosaic virus (MYMV) and cercospora leaf spot (CLS) [caused by Cercospora cruenta Sacc. or Cercospora canescens Ell. & Mart.].

Barimung‐4 was developed from the cross Sonamung (Bangladeshi landrace) and ‘Barimung‐2’ (a cultivar released by PRC, BARI in 1984). Single plant selections were made in the F3 Forty‐nine F4 families were developed from this particular cross and evaluated in plant progeny rows in 1988 to 1989, and 27 F4 families were selected and tested as F5 families the following year. In the F5, eight families were retained as promising and were evaluated as F6 lines. Days to maturity, reaction to diseases, growth habit, podding intensity and seed yield were given priority during selection. The eight F6 lines were evaluated in a replicated trail in 1990 to 1991 and seed was bulked. The bulked line was assigned the station identification number BMX 841121. This line was evaluated in preliminary, advanced and regional yield trials from 1991 to 1992 and 1993 to 1994 at four locations (BARI, 1994).
