Horticulture, KeraJa Agricult .iral University, Vellanikkara during rabi (2004) and
summer (2005).
Thirty SIX brinjal accessions collected from different parts of the country were
characterized for different qualitative and quantitative characters. The evaluated
accessions exhibited considerable variation for growth habit, prickliness of plant parts,
colour, shape and size of fruits and colour of petiole, leaves, stem and flowers.
Fruit yield was maximum in FJ hybrid, Neelima and S1'.1 384. Swethe and Swetha
X Haritha were early and produced maximum number of fruits per plant. Longest fruits
were produced by SM 344. Fruits of SM 385 recorded maximum girth and SM 354 had
hcav iest fruits.
The study revealed high heritability coupled with high genetic advance for
characters like fruit length, number of fruits per plant, days to last harvest and number of
economic harvests. Yield was positively associated with number of fruits per plant
:;JiT!ber of economic harvests and total harvests.
The accessions SM 363, SM 364, SM 366, SM 384 and SM 385 were found
._<slant to jassid infestation in the field screening and under cage studies.
T he morphological and anatomical bases of resistance was also studied. l ligh
r • Lb hair density and longer midrib hairs were found to impart resistance in
resistant/ tolerant accessio: tS. The anatomical studies of midrib of resistant and
usceprible accessions revealed variation in cuticle thickness, cell wall thickness of
epidermal cells and inter cellular space of hypodermal cells. These characters either
alum' or in combination may be contrib ting resistance to oviposition and feeding of
jassids ill brinjal
