    Notes: Abstract The effect of signal-modulated optical radiation on the characteristics of a GaAlAs/GaAs MODFET has been studied analytically. It is found that the offset voltage increases with modulation frequency and the effect of frequency is negligible above 5 MHz. The drain-source current decreases with increase in signal frequency at a constant radiation flux density, doping concentration and drain-source voltage. Studies on sheet concentration and transconductance also show that the signal frequency has a significant effect upto a certain modulation frequency (≲5 MHz) above which the effect of frequency is insignificant.

    Notes: Summary The inheritance of the dwarf plant type was studied in blackgram (V. mungo (L.) Hepper). ‘Type 9’ has erect plant type with normal internode length. The mutant line, ‘EMSD’ has reduced internode length. The F1, F2 and F3 generations of a cross between ‘Type 9’ and ‘EMSD’ and its reciprocal were studied. The extreme dwarf plant type appeared to be governed by a single recessive gene, dw 1 dw 1 with no cytoplasmic effect.

    Notes: Summary The allelic relationship of resistance genes for MYMV was studied in blackgram (V. mungo (L.) Hepper). The resistant donors to MYMV — ‘Pant U84’ and ‘UPU 2’, and their F1, F2 and F3 generations — were inoculated artificially using an insect vector, whitefly (Bemisia tabaci Genn.). The two recessive genes previously reported for resistance were found to be the same in both donors.

    Notes: Summary The inheritance of resistance to mungbean yellow mosaic virus (MYMV) was studied in blackgram (Vigna mungo (L.) Hepper). The highly resistant donors Pant U-84 and UPU-2 and a highly susceptible line, UL-2, their F1's, F2's and backcrosses were grown with spreader located every 5 to 6 rows. The resistance was found to be digenic and recessive in all the crosses and free from cytoplasmic effect.

    Notes: Summary This review is given on the origin and interrelationship of blackgram and greengram: the symptoms, mode of transmission, and host range of important diseases, namely: mungbean yellow mosaic virus, leaf crinkle virus, leaf curl virus, mosaic mottle virus, Cercospora leaf spot, powdery mildew, root and stem rots, bacterial leaf spot and halo blight. The screening for resistance, sources of resistance, including interspecific hybridization, and induced mutations, as well as the genetics of resistance are treated along with suggestions for future breeding strategies of these crops.
