Abstract
Mungbean advanced lines derived through hybridization from different cross. Combinations and the released varieties have been evaluated at NIFA, Peshawar for some important agronomic traits and screened for Mungbean Yellow Mosaic Virus (MYMV) during kharif season 2002. The genotypes/varieties have shown highly significant genetic variability for the studied traits. The high yielding mungbean recombinants have shown 1603 to 2443 kg/ha yield, large seed size (40.8-55.6 g/1000 seed weight) and MYMV rating from resistant to highly resistant. The days to flowering and physiological maturity of the recombinants were found in range from 30-52 days and 64-93 days, respectively. The genotypes, which took less than 70 days for physiological maturity, were NFM-3-3, NFM-6-2, NFM-6-5, NFM-7-3, NFM-7-6, NFM-7-13, NFM-8-1, NFM-8-2, NFM-8-22 and NM 92. The short stature genotypes (below 50 cm) were NFM-7-3, NFM-12-15 and NFM-12-16. The genotypes NFM-6-2, NFM-7-6, NFM-12-9, NFM-12-12, NFM-12-14, NFM-12-15, NFM-13-2 and NFM-13-4 have produced more than 2.0 tones yield per acre. The genotypes NFM-7-3, NFM-8-22, NFM-12-9, NFM-12-18 and NM 54 exhibited seed size above 55g/1000 seed weight. The genetic variability in the newly developed mungbean genotypes for physiological maturity, plant height, seed size and seed yield reported in this paper could be used directly to evolve mungbean variety or to incorporate these traits in other genotypes through hybridization for the improvement of this crop in the province.
