(A:PS)
Losses in grain yield due to leaf crinkle disease at Hissar, ranged from
2.12 to 93.98/ in mungbean cultivar Varsha and 2.82 to 95.17% in blackgram
cultivar T-9. There was a statistically significant decrease in yield in terms
of pods per plant, seeds per pod and iUOO-grain weight in prebloom infected
plants. A direct correlation between the stage of plant growth at which
infection occurred and loss in grain yield was observed. The earlier the
infection, the greater was the loss, which was mainly attributed to reduction
in the number of pods. [AS]

[En] (A:PS)
Sixty plant species belonging to 9 families were tested to find new hosts
of blackgram leaf crinkle virus, in addition to mungbean, cowpea and moth bean,
which are known hosts. Only cucumber and bottle gourd could be infected. No
local lesion host could be found. [EMS]
