Characterization of Genetic Resources and Identification of Selection Indices of Brinjal (Solanum melongena L.) Grown in Eastern India

Abstract

SummaryThirty five diverse genotypes of brinjal collected from different parts of Eastern India were characterized as per the documented descriptors and were evaluated for their morphological and yield component characters during autumn-winter season. All the brinjal genotypes under study showed highly significant variations among twelve quantitative traits. However, a wide range of days to 50% of flowering (47-79), fruit length (8.70 -23.90 cm), fruit girth (2.67-10.30 cm), fruit weight (52.33-319.37 g), number of marketable fruit per plant (4.33-12.00) and marketable fruit yield per plant (0.39-1.68 kg) among the genotypes was observed. Three characters namely, fruit weight, plant height and days to 50% of flowering exhibited high heritability and genetic advance indicating that such situation may arise due to the action of additive genes controlling the characters. The genotypic and phenotypic correlations agreed closely with each other. Fruit weight and fruit girth exhibited significantly positive correlations with marketable fruit yield per plant. Among the eleven yield component traits, fruit weight and number of marketable fruits per plant showed highly positive direct effect on marketable fruit yield per plant. Attention should be paid on selection based on marketable fruit weight and number of marketable fruits per plant for marketable yield improvement of brinjal.

Genetic variability, characters association and path analysis for yield and fruit quality components in Brinjal

“…Number of branches per plant also had negative correlation co-efficient values though they are of low magnitude. These correlations among the yield components were in agreement with that of Chattopadhyay et al (2011), Singh et al (2011), Karak et al (2012 Kranthirekha and Celine (2013), Prabhu and Natarajan (2008), Dharwad et al (2009), Thangamani andJansirani (2012) and Solaimana et al (2015) in brinjal. It was quite obvious that positive correlation were found between TSS and total sugars; total phenols and DPPH FRS capacity; and negative correlation between moisture content and TSS.…”

Genetic Variability in Eggplant for Agro-Morphological Traits

“…Mature fruit weight and diameter of mature fruit also exhibited a highly significant positive correlation with each other. Similar results for fruit diameter and fruit weight were been observed in a recent study (Chattopadhyay et al, 2011). Relationship between leaf and fruit size was not significant in the current study that have already been found by a previous researcher (Hazra et al, 2003).…”

“…Islam and Uddin (2009) performed the characterization of 16 genotypes of local and exotic germplasms of brinjal to study variation present among them. Chattopadhyay et al (2011) performed characterization of thirty five diverse brinjal genotypes which showed highly significant variations among twelve quantitative traits. They recommended paying attention on selection based on marketable fruit weight and number of fruits per plant for yield improvement of brinjal.…”

Correlation Studies in Segregating Population of Brinjal (Solanum melongena L.) Developed Through Bi-Parental Mating Using Bacterial Wilt Resistant Varieties

“…In case of BIP's, marketable fruit yield per plant showed significant and positive correlation with number of marketable fruits per plant, plant height and fruit weight whereas it was negatively and significantly associated with bacterial wilt incidence. Chattopadhyay et al, (2011), Karak et al, (2012), Nayak and Nagre (2013) and Lakshmi et al, (2014) have also recorded similar results in brinjal. Among the component characters, days to 50% flowering had positive and significant association days to first picking, fruits per plant, whereas it was negatively correlated with bacterial wilt incidence.…”
