10. High Yielding Mungbean [Vigna radiata (L.) Wilczek] Variety “NIFA Mung-2017”
Abstract
National yield of mungbean is low as compared to other countries, mainly due to shortage of commercial mungbean varieties. To address this issue, an exotic Mungbean Yellow Mosaic Virus (MYMV) susceptible accession VC 1973A and a local MYMV resistant genotype NM 92 were crossed (VC 1973A x NM 92) at the experimental field of the Nuclear Institute for Food and Agriculture (NIFA), Peshawar during kharif 2004. Selection for best recombinant lines based on high yield (more pods per plant), resistance to MYMV, semi erect plant type in early segregating populations, and genetic stability in F2 - F5 generations for the desired traits was carried-out from 2005 to 2010. The high yielding recombinant “NFM-6-5” along with other advanced lines and local standard variety “Ramzan” were screened for MYMV resistance, and tested for seed yield and other related components in various yield trials i.e. preliminary, advanced, multi-locations and National Uniform Yield trials from 2011-2015. Results revealed that recombinant “NFM-6-5” produced up to 2283 kg ha-1 seed yield in replicated yield trials with 25-30% higher seed yield compared to the check variety “Ramzan” in various yield trials. More number of pods per plant and large seed size are the main primary yield contributing components in NIFA Mung-2017 (recombinant “NFM-6-5”). NIFA Mung - 2017 is a promising variety with different genetic background from earlier mungbean varieties. Khyber Pakhtunkhwa Provincial Seed Council approved the recombinant “NFM-6-5” as a commercial variety with name “NIFA Mung-2017” for general cultivation in Khyber Pakhtunkhwa (KP) on 19th September 2017.
