(Phaseolus aureus) to Cercospora leaf spot. INDIAN JOURNAL OF MYCOLOGY AND<br />
PLANT PATHOLOGY, v.5:207. [En] (REP.MB-2412)<br />
The results of field testing of 730 mungbean varieties for resistance to<br />
Cercospora leaf spot are presented. Only 9 varieties were found to be<br />
resistant. [THH]<br />

1976. Note on the evaluation of black gram (Phaseolus mungo L.) and green gram<br />
(P. aureus Roxb.) varieties for resistance to powdery mildew (Erysiphe polygoni<br />
DC.). MADRAS AGRICULTURAL JOURNAL, v.63(2):139-140, [En] (REP.MB-199b)<br />
Powdery mildew, caused by Erysiphe polygoni, is a major disease of mungbean<br />
and blackgram in Tamil Nadu. Twenty-two varieties of mungbean and 13 varieties<br />
of blackgram were tested for their reaction to this disease under field<br />
conditions in 1973. None of the varieties of mungbean and blackgram were<br />
resistant to the disease. S 9, CO 1, and PS 7 of mungbean and CO 1 of blackgram<br />
were less susceptible. [THH]<br />

tolerance of some greengram types to yellow mosaic. MADRAS AGRICULTURAL<br />
JOURNAL, v.63(i):54-55. [En] (REP.MB-1997)<br />
Germplasm collections maintained at Tamil Nadu Agricultural University were<br />
screened for yellow mosaic resistance during March-May 1974, when there was<br />
severe natural incidence of the disease. The types which showed resistance were<br />
grown in different seasons at three different localities. Only two varieties,<br />
LM 220, and PLS 274 were free from the disease in all six seasons in the three<br />
places. However, when these two were tested under greenhouse conditions, they<br />
were susceptible (10 and 15% incidence, respectively) to the disease. [THH]<br />

tolerance of some blackgram varieties to root rot disease caused by<br />
(Macrophomina phaseolina). MADRAS AGRICULTURAL JOURNAL, v.63(3):176-178.<br />
[En] (REP.MB-1770)<br />
Germplasm collections of blackgram maintained at Tamil Nadu Agricultural<br />
University were screened for the root rot disease caused by Macrophomina<br />
phaseolina. The trials were conducted at three localities in different seasons.<br />
The present studies reveal that the field tolerance of blackgram varieties<br />
varies from season to season and locality to locality. LTHH]<br />

screening of greengran germplasm against yellow-mosaic virus disease in India.<br />
INDIAN JOURNAL OF AGRICULTURAL SCIENCES, v.46(5):243-245. [En] (REP.MB-1165)<br />
All 620 lines of mungbean collected from 14 countries were screened for<br />
resistance to mungbean yellow mosaic virus at the farms of the Punjab Agric.<br />
Univ. at Ludhiana (in 1972 and 1973) and Gurdaspur (in 1973). The results of<br />
field screening done at Ludhiana during the wet season of 1972 indicated that 3<br />
