Diversity of Genetic Resources and Genetic Association Analyses of Green and Dry Chillies of Eastern India

Abstract

1Chilli (Capsicum annuum L.) is regarded as one of the main commercial vegetable and spice crops at the global level. Maximum diversity can be noted among the cultivars/landraces available in India with respect to shape, size, yield, quality, and other traits. The present experiment was conducted to identify the most promising chilli variety suited for green and dry purposes, to study the genetic variability for different traits and to assess the association of different yield attributing traits with the green and dry yield of chilli. Thirty four genotypes were characterized during a 2-yr period. Most of the genotypes possessed the character constellation of C. annuum. Two genotypes, 'Chaitali Pointed' and 'BC CH Sel-4' were found most promising with respect to green fruit yield (272.79 g, 221.10 g per plant) and dry fruit yield (54.56 g, 44.44 g per plant). Phenotypic and Genotypic Coefficient of Variation values for green fruit weight (119.95%, 111.26%), green fruit girth (89.76%, 48.93%), weight of red ripe fruit (112.02%, 111.93%), weight of dry fruit (111.63%, 110.97%) and number of fruits per plant (86.05%, 85.02%) were recorded to be high. Green fruit yield per plant, ascorbic acid content, and number of fruits per plant also showed very high broad-sense heritability and genetic advance. From the study of correlation and path coefficient analyses, the number of fruits per plant, green fruit length for green chilli, weight of dry fruit and the number of fruits per plant for dry chilli were found to the most important selection indices.

Selection parameters for fruit yield and related traits in chilli (Capsicum annuum L.)

“…High heritability estimates was recorded for all the characters which ranged between 68.47 and 98.44%. These results were in agreement with Chattopadhyay et al (2011). Genetic advance was high for capsaicin content (146.39%).…”

Evaluation of Chilli Genotypes for Yield Attributing and Incidence of Leaf Curl and White Fly Traits in Coastal Maharashtra, India

“…Similar results were reported by Chattopadhyay (2011), Sharma et al, (2010. Indirect effect on yield by number of branches per plant and plant spread were reported by Tembhurne et al, (2008).…”

“…Similar results were also recorded by Sharma et al, (2010), Chattopadhyay et al, (2011), Vijaya et al, (2014 and Ukkud et al, (2007).…”

“…The similar variation in fruit diameter was observed by Ukkund et al, (2007), Tembhurne et al, (2008), Chattopadhyay (2011) and Thul et al, (2009).…”

Character Association and Path Coefficient Analysis for Qualitative and Quantitative Traits in Green Chilli Genotypes (Capsicum annuum L.)

“…The biochemical parameter viz., ascorbic acid also has direct positive effect towards yield (0.223, 0.296) which is in consonance with Chattopadhyay et al, (2011), Vikram et al, (2014 and Patel et al, (2015). Thus, the direct selection for these traits would be rewarding for improvement of economical yield.…”
