Description "Green gram (Vigna radiata l.) is an important pulse crop
grown in India. It is also suitable in all the agro-ecological situations. It
belongs to family Leguminoceae and sub-family Papilionaceae. It has
12 pairs of chromosomes (2n=24). Green gram is originated in India
and Central Asia. It is also known as mungbean, moong etc.
Green gram contributes 14 per cent in total area and ?per
cent in total pulses production in India. It has been reported that green
gram has been cultivated in India since ancient times. It is believed that
green gram is grown in these regions since prehistoric times. It is
widely cultivated throughout Asia. It is a protein rich staple food and
contains about protein-24 .5 per cent, fat-1 .2 per cent, fibre-0 .8per cent,
minerals-3.5 per cent, carbohydrates-59.9 per cent, calcium-75mg,
phosphorus-405mg, iron-8.5mg and small amount of vit. 8 complex."
"An investigation entitled ""VARIABILITY STUDIES IN
M3 GENERATION IN MUNGBEAN (Vigna radiata (L.) Wilczek)"" was
conducted during kharif 2011 at the field of Pulses Research Unit, Dr.
PDKV, Akola. Seeds of AKM-8802, PKV Green gold and AKM-4 of
mungbean varieties were exposed to gamma rays doses of 150, 250
and 350 Gy to assess the variability generated for various yield and
yield contributing characters in M3 generation. The bulk seed
of M2 generation was sown in randomized block design with three
replications and the 220 mutants isolated in M2 were grown in plant to
row progenies in non replicated trial for their confirmation. Out of 220
mutants only 28 lines showed true to type breeding behaviour in M,
generation.
The PCV values were higher than GCV values for all the
characters. The characters sprouting percentage, number of pods per
plant, number of seeds per pod and 100 grain weight exhibited high
GCV and PCV values. High estimates of heritability were recorded for
sprouting ·percentage, number of seeds per pod, number of pods per
plant, pod length, 100 grain weight and plant height.
The characters sprouting percentage, number of pods per
plant and plant height had high heritability values along with high
estimates of genetic advance, indicating the presence of additive gene
action and direct selection for such traits is rewarding in crop
improvement. High heritability estimates along with low genetic
advance values were recorded for pod length, number of seeds per
pod and 100 grain weight showing the presence of non additive gene
effects.
Apart from variability studies variety and dose wise mean
performance was analyzed for 12 characters. In the present
investigation treatment 250 Gy was found more efficient and effective
in AKM-8802 and AKM-4. And the treatment 350 Gy was found more
efficient and effective in PKV Green gold, for various yield and yield
contributing traits. It can be expected that modern mutation breeding
technologies in combination with refined selection methods applicable
to large populations would continue to be of great potential for the
improvement of crop plants."
