green gram. SABRAO JOURNAL, v.17(2):165-171. [En] [En Abst] (A:PS)
The Jnerallelic relationships of resistance/susceptibility genes to yellow
mosaic in mungbean were investigated. The parents Tarai Local (resistant-R), L
80 (moderately resistant-MR), L 294-1 and LM 214 (tolerants-T) and Jawahar 45
and G 65 (susceptible-S) were intercrossed and 14 Fl crosses were recovered.
The Fl crosses of R x S, MR x S and T x S showed moderately susceptible to
susceptible reactions which indicated resistance to be a recessive character.
The response from F2 and F3 generations revealed the presence of duplicate
recessive genes. Fl reactions ot R x MR and R T were wod...dLely resibLant to
tolerant suggesting again the higher degree of resistance to be recessive. F2
and F3 reactions indicated the involvement of an inhibitory gene. The Fls of T
x T were susceptible and F2 and F3 reactions showed the possibilities for the
presence of complementary genes. The genic interactions confirm the genetic
constitution of the parents as; =

respond for susceptibility and I behaves as an inhibitor. [AS]

giving resistance to mungbean yellow mosaic virus in blackgram. THEORETICAL
AND APPLIED GENETICS, v.72(6):737-738. [En] [En Abstj (REP.MB-2811)
The allelic relationship of resistance genes for mungbean yellow mosaic
virus (MYMV) was studied in blackgram (V. mungo (L.) Hepper). The resistant
donors to MYMV - 'Pant U84' and 'UPU 2', and their Fl, 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. [AS]

mung beans (Phaseolus aureus Roxb.). RADIATION BOTANY, v.14(2):85-89. [En]
(REP.MB-0237)
Seeds of cultivar 6601 were exposed to gamma radiation at doses of 10 to 40
kR and the effects on flowering time, plant height, pods per plant, pod length,
grains per pod, 100-grain weight and plant yield were studied. In the M2
generation, positive or negative shifts occurred in the mean values for all the
polygenic traits except mean pod length, which remained unchanged. The
coefficient of variability increased in all treatments for all the traits. [PBA
