RELATIONSHIP OF
QUANTITATIVE TRAITS WITH TWO VIRAL DISEASES IN MUNGBEAN (VIGNA
RADIATA (L.) WILCZEK)
MUHAMMAD ZUBAIR1*,
SAIF ULLAH AJMAL2 AND NASIR MAHMOOD CHEEMA3
Abstract:
Mungbean germplasm
comprising 262 lines was evaluated for resistance and susceptibility of
MYMV and ULCV. Data on 9 quantitative characters viz., branches per
plant, Pod length, pods per plant, seeds per pod, grain yield per plant,
100-grain weight, biological yield per plant and harvest index (%)
showed that 211 accessions which were 80.53% of the population, proved
to be resistant to MYMV, whereas remaining 51 (19.47%) were susceptible
to the disease. In case of ULCV, 242 accessions which were 92.37% of the
population, proved to be resistant, whereas remaining 20 (7.637%) were
susceptible to the disease. Relationship of the disease with QTLs using
‘t’ statistics revealed that MYMV was associated significantly with all
the characters except with pod length and 100 seed weight. Similarly
ULCV was also associated significantly with all the characters except
pod length, pods per plant and 100 seed weight.
