GENETICALLY CO TROLLED FLORAL ABNORMALITIES IN EGG-PLANT

Published on

DURING a survey of vegetable crop varieties in the Union territory of Delhi, a solitary
plant characterised
by excessive branching, flowering and fruitlessness was observed
in the year 1958 in the brinjal crop of the variety
'baingani' in the village Azadpur.
On closer examination of the plant, it was found that the stigma and style had 3-6
longitudinal splits (Fig. 5) and the anthers were shortened, one of the anther-lobes
being shorter than the other (Figs. 1 and 3). Further, the usual apical dehiscence of
the anthers was absent. The stigma and style as also the anther of the normal flower
are shown in Figures 6, 2 and 4. The normal and abnormal flowers are shown in
Fig. 7.
The abnormal plant was transplanted into the experimental plots of the Institute and
was selfed and also crossed
with the normal using the latter as a pollen parent. No
fruits were formed in both the cases. However', both fruit formation and seed setting
took place when the normal flowers were pollinated with pollen from the abnormal
plant.
