Dry root rot caused by Macrophomina phaseoli is one of the serious diseases
of blackgram in the Punjab. The disease manifests at the time of crop maturity
when the whole plant dries, the pods shrivel, grains poorly formed and reducing
the yield as well as quality. During kharif 1972, 91 lines of blackgram were
sown in heavily infested soil with M. phaseoii. Only one variety, BR 68, had
great potential showing freedom from the disease. [THHJ

Mungbean varieties, N 122, PS ib, and blackgram, Mash 64, Mash 1-I, and G
31 showed less susceptibility to mungbean yellow mosaic virus in two field
experiments at Madurai, Tamil Nadu, India. [THHJ

In the varietal screening studies, 157 cultLivars of mungbean (123 exotic+34
indigenous) and 118 of blackgram (92 exotic+26 indigenous) were tested for
genetic resistance to yellow mosaic virus during the summers of 1972 and 1974
under natural conditions. The severely infected plants were recorded and
grouped into 5 categories, viz., 0-10%, 11-30%, 31-50%, 51-70% and 71-100%. No
variety of mungbean could be found resistant; only 6 local collections showed
some tolerance. In Lhe case of blackgram, 17 exotic and 8 indigenous types were
highly resistant and 50% of the total material was fairly tolerant. A great
scope exists for varietal improvement in blackgram through hybridization. [AS]

Evaluation of mungbean (Vigna radiata L. Wilczek) germplasm. CROP
IMPROVEMENT, v.2(1&2):99-I04. [En] [En Abst] (REP.MB-2446)
Four hundred and thirty-five strains of mungbean originating from 14
countries were evaluated in a replicated trial for days to flower, days to
maturity, plant height, primary and secondary branches, clusters per plant,
pods per plant, pod length, seeds per pod, 100-seed weight, grain yield,
protein content, yellow mosaic virus, Cercospora leaf spot and bacterial blight
disease. Agronomic characters of 21 (5%) top yielding lines indicated that they
possessed more number of pods per plant, more number of seeds per pod and
medium seed size. Protein percentage ranged from 16.20 to 29.30 in the
germplasm screened. Two strains, 15229 and L 24-2, were resistant to both
yellow mosaic virus and bacterial blight; 15229 was also resistant to
Cercospora leaf spot disesase. [AS]
