| More Details: | A field experiment was conducted in the field laboratory of the Department of Genetics and Plant Breeding of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur during the period from October 2018 to April 2019. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The objective of the study was to determine the genetic variability and correlation for yield and yield related traits of the chilli genotypes. Seeds of 28 chilli genotypes were collected from different sources and were raised in polybags and then transplanted to raised bed. The experiment was laid out in a randomized complete block design with three replications. Data on yield and yield related traits were recorded at the respective stage of the crop. Among the studied genotypes, the fruit length (FRLN) varied 1 cm to 16.3 cm with an average length of 6.5 cm. The lowest fruit diameter (FRDM) was 3.3 mm and the highest was 15.1 mm. The fruit yield ranged between 0.018 kg/plant and 1.044 kg/plant. The lowest fruit weight was recorded 0.3 g, while the largest fruit weight was 6.3 g. The highest significant genotypic and phenotypic variance was found in number of fruits/plant and GCV and PCV were found highest in fruit yield/plant. A fair amount of heritability with high genetic advance was found in number of fruits/plant which indicates that the heritability is due to additive gene effects and the selection might be very effective in chilli breeding. Among the agronomic parameters, fruit yield/plant was significantly correlated with individual fruit weight and the amount of seeds/plant. It was also found that the height of chilli plant positively influenced the amount of fruits/plant. However, plant height negatively affected fruit diameter and number of fruits per plant. The results of the present study suggests that there is a great genetic potential in the studied genotypes. [Fundam Appl Agric 2024; 9(1.000): 44-50] |
