Abstract
The study on Performance assessment of Pudukkottai local Brinjal was conducted during 2017-2018 in and around the villages of Pudukkottai district of Tamil Nadu with an objective to identify the elite genotypes. In Pudukkottai, four genotypes of local brinjal were considered as the best genotypes. Hence, various morphometric and quality characters were observed in all the four genotypes and finally one best performing genotype was selected for further evaluation. In this study, closer study of four selected genotypes which gives medium sized fruits with better yield and cooking quality were undertaken. Four selected genotypes (Sm1, Sm2, Sm3, Sm4) were evaluated based on PPV & FRA descriptor. Morphological characters like Plant height, Plant spread, Plant growth habit, Anthocyanin coloration of stem, Stem pubescence, Leaf length, Leaf width, Leaf spininess, Leaf blade colour, Colour of veins, Intensity of colour of veins, Flower size, Flower colour, Flowering time (Days After Sowing), Number of flowers, Fruiting pattern, Fruit length, Fruit width, Fruit shape, Fruit stripes, Fruit shininess, Colour of calyx, Spininess of calyx, fruit yield were recorded for all the selected four genotypes.
The plant height showed a variation ranging from 120.00 to 72.00 cm with mean of 90.00 cm. Plant width showed a variation ranging from 67.80 to 50.00 cm with mean of 56.50 cm. Out of the four genotypes studied for plant growth habit, all are having semi spreading growth habit. Regarding, stem pubescence, Sm2 is having strong stem pubescence.
Leaf characters viz., Leaf length, Leaf width, Leaf spininess, Leaf blade colour, Colour of veins, Intensity of colour of veins exhibited considerable variations .The leaf length showed a variation from 14.80 to16.63 cm with the mean of 15.66. The width showed a variation from 11.80 to 12.30 cm with the mean of 12.14. Genotypes viz., Sm2, Sm3 showed presence of spines in leaves, Sm1, Sm2 showed purple colouration of veins and Sm1 showed strong intensity of vein colouration.
Flower characters like Flower size, Flower colour, Flowering time, Number of flowers per plant were observed. From the observations, Sm1, Sm2 and Sm4 have medium sized flowers. Sm3 have small sized flower. Genotypes Sm1, Sm2 has dark purple coloured flowers. Sm3, Sm4 has light purple colour flowers. Regarding flowering period Sm2 showed an earlier flowering period of less than 65 days. Sm1, Sm3,Sm4 showed medium flowering period of 65 to 75 days. Number of flowers per plant showed a variation from 5.00 to 10.00 with a mean of 7.25.
Variability in fruiting pattern was observed as follows. Fruit diameter (cm), Fruit Length (cm) for the selected brinjal genotypes was observed. The entire genotypes showed solitary fruiting pattern except Sm4. Sm4 is having cluster fruiting pattern. Fruit length showed a variation of 13.00 cm to 5.90 cm with a mean of 8.65 cm. Fruit diameter showed a variation of 13.40 cm to 11.00 cm with a mean of 12.10 cm. Sm1, Sm2, Sm4 showed ovoid shape and Sm3 showed globular shape. Fruit stripes were found in Sm3. Spininess was found more in Sm2. Sm1 showed a higher fruit yield of 41.00 t/ha followed by Sm2 with a yield of 39.50 t/ha. Fruit to seed ratio was found to be more in Sm2, followed by Sm1, Sm3 and Sm4. Similarly, fruit borer incidence was found to be more in Sm4. Sm2 showed lesser fruit borer incidence due to its spininess on fruits.
In a nutshell, based on the yield and in quality aspects, the genotype Sm2 (Sellugudi) was found to be highly promising followed by Sm1 (Aalavayal) and hence Sm2 and Sm1 are recommended for further evaluation.
