A NEW HIGH YIELDING MUNGBEAN (VIGNA RADIATA (L.) WILCZEK) VARIETY "RAMZAN" FOR THE AGRO CLIMATIC CONDITIONS OF NWFP G. S. S. KHATTAK*, M. ASHRAF**, I. SAEED AND B. ALAM
Abstract: An exotic genotype VC 1482C and a local mungbean genotype NM 92 were
hybridized at the Nuclear Institute for Agriculture and Biology (NIAB),
Faisalabad during kharif (July-October) 1998. Selection of the high
yielding recombinant NFM-12-12 from segregating populations, and evaluation
in various replicated yield trials for yield potential and stability
test were carried out from 1999 to 2004. The proposal of the recombinant
NFM-12-12 was submitted for approval as commercial variety for NWFP
to the Provincial Seed Council meeting held on 19th September 2005 at
NWFP Agricultural University, Peshawar. The Provincial Seed Council
approved the recombinant NFM12-12 as a commercial variety under the
name "Ramzan" for general cultivation in NWFP.
The major improvement in NFM-12-12 is manifested in the form of increase
in seed size, decrease in plant height, stiff stem and earliness in
maturity by a margin of 10 days as compared to standard variety NM 98.
The large seed size of NFM-12-12 is the main contributing factor towards
the increase in seed yield compared to NM 98. The high harvest index
of NFM-12-12 invokes its greater physiological efficiency in partitioning
the photosynthates towards grain formation leading to marked increase
in grain yield. Short stature and stiff stem of NFM-12-12 helps in showing
resistance to lodging. Clusters per plant, pods per plant, branches
per plant, pod length, seeds per pod and protein contents of NFM-12-12
also compare favorably with parent NM 92 and standard NM 98. NFM-12-12
has 28-36% high seed yield potential compared to the standard variety
NM 98 and parent NM 92. An average experimental seed yield of Ramzan
was 1962 kg ha-1 at NIFA, Peshawar. Nuclear Institute for Food and Agriculture (NIFA), Peshawar, NWFP, Pakistan.
