Abstract
The present investigation entitled "Evaluation of brinjal
germplasm (Solanum melongena L.)" was carried out during Kharif season of
2014-15 at Instructional-Cum-Research Farm, Department of Horticulture,
College of Agriculture, Latur, VNMKV, Parbhani. The study was under taken
with eighteen genotypes of brinjal with two replications in Randomized Block
Design.
The sowing ofbrinjal seeds was done on 2nd week of July 2016 on
raised beds. The transplanting of seedlings was done at spacing 60 x 45 em in
the field. There were 20 plants of each genotype in each plot. Five plants were
randomly selected from each replication to record the observations on different
growth, yield and quality characters.
A wide range of variations were observed among different
genotypes for all growth, yield and quality parameters. The phenotypic
coefficient of variation was higher than genotypic coefficient of variation for all
the traits. High (>20 %) genotypic coefficient of variation (GCV) and
phenotypic coefficient variation (PCV) were observed for fruit dry • matter
percentage; fruit yield per plant, weight of fruits, leaf petiole length, fruit yield
per hectare, fruit yield per plot, plant height and days required for first flowering.
High heritability (>60 .%) coupled with high genetic advance as
per cent over mean (>20 %) were recorded for the characters viz., plant height,
leaf petiole length, days required for first flowering, fruit pedicel length, fruit
length, fruit diameter, number of fruits per plant, weight of fruits, fruit yield per
plant, fruit yield per plot, fruit yield per hectare, fruit dry matter I?ercentage and
fruit protein percentage. Therefore, additive component is predominant here.
Plant height, fruit length, fruit diameter, number of fruits per plant,
fruit weight, fruit yield per plot was positive and significantly correlated at both
levels. While, highest positive direct effect on fruit yield per plant was shown by
fruit yield per plot followed by fruit. diameter, plant spread, fruit length, number
of primary branches per plant and number of fruits per plant. Highest negative
direct effect were exhibited by fruit yield per hectare, plant height, fruit weight,
fruit dry matter percentage and number of fruits per cluster.
Thus, it can be concluded that, as per variability studies the
genotypes Pusa Purple round, Panrutti, Gulabi and Kateri Wangi performed
good performance for yield and yield contributing characters. These may be used
for further breeding programme for improvement of brinjal yield.
