In the last half of 1972 until the end of 1973, the AVRDC mungbean program
was concentrated on collecting as many cultivars as possible from world
sources, then to screen this collection for response to population density,
day-length and other climatic variations and for resistance to insect and
disease attack. In addition, the basic physiology of this crop was studied to
understand better critera for selection of the breeding materials. A brief
description of the status of breeding program was included. [PLHJ

In 1974, the world collection of mungbean germplasm was increased by 546
cultivars and totaled 2,362 accessions at the end of the year. This germplasm
was shared with 24 scientists in 15 different countries. A cultivar from
Taiwan, Tainan 1, produced a yield of 2.46 t/ha in a yield trial at AVRDC.
Twenty cultivars produced a mean yield of 1.86 t/ha or about triple that
obtained by most farmers in Southeast Asia. The most significant findings in
1974 were the identification of sources or resistance to several important
mungbean diseases. Three cultivars were consistently resistant to Cercospora
leaf spot. V. 1140 was determined to be immune to powdery mildew (Erysiphe
polygoni). More than 350 F3 seeds were collected from an interspecific cross
between mungbean and rice bean. [PLH]

In 1975, mungbean germplasm collection contained almost 4,000 entries at
the end of the year. V 2184 had an average yield of 1800 kg/ha. Ten cultivars
were found to be resistant to Cercospora leaf spot, and another six were
resistant to Rhizoctonia sp., Pythius sp. and Fusarium sp. V 1735 was the least
infested by beanfly. Beanfly control in mungbean was successfully attained by
applying carbofuran G at 2 kg a.i./ha to soil at planting or by spraying
Hostathion w-ekly at 0.25 kg a.i./ha. [PLHJ

In a series of field screenings using artificial inoculation, 12 cultivars
were resistant to powdery mildew, 17 cultivars were resistant to Cercospora
leaf spot, and 23 cultivars were resistant to MMV. BCM at 1.5 g a.i./l and
benomyl at O.b g a.i./l provided the best protection from Cercospora leaf spot
in a summer planting of a highly susceptible cultivar under artificially
