Performance of Chilli (Capsicum annuum L.) hybrids for yield and quality traits

Abstract

Twenty-eight F1 combinations of chilli (Capsicum annuum L.) obtained from half-diallel cross along with eight diverse parents were evaluated in a field study to elucidate the information on the extent of mean performance of various horticultural traits. The analysis revealed that all the genotypes possessed wide spectrum of variability and showed significant differences for parents and hybrids for the traits studied. For parents UHF CHI 13 (216.20), UHF CHI 15 (193.80), UHF CHI 5 (139.00) and for hybrids H1 (182.60), H9 (181.40) and H7 (172.80) hold highest fruit count per plant. The parents UHF CHI 5 (1047.13 g), UHF CHI 15 (949.62 g) and UHF CHI 7 (912.61 g) and cross combinations H17 (1535.10 g), H8 (1320.00), H6 (1229.76) and H18 (967.60) recorded the high ripe fruit yield per plant. As for earliness, parents UHF CHI 5 (43.33), UHF CHI 11 (45.00), UHF CHI 7 (45.33) and hybrids H27 (42.67), H26 (43.00) and UH28 (43.00) took minimum days for flowering. For pungency UHF CHI 12 (0.28%), UHF CHI 13 (0.26%), DKC-8 (0.24%) and H23 (0.33%), H5 (0.31%), H26 (0.26%) recorded high capsaicin content.

Interacción genotipo/ambiente y estabilidad del rendimiento en líneas avanzadas de ají Topito (Capsicum chinense)

“…Las diferencias significativas encontradas para la interacción G×E para las variables rendimiento, NFP y PF, indican que los cultivares responden de diferente manera a los cambios ambientales, esto concuerda con lo reportado por diferentes autores (Gurung et al, 2012;Rao & Tembhurne, 2013), los cuales coinciden que variables de tipo cuantitativo como el rendimiento y sus componentes tienen una alta proporción de la varianza asociado al factor ambiental. Esto afianza la necesidad de establecer ensayos en múltiples ambientes que permitan a los fitomejoradores detectar aquellos materiales con mayor potencial de rendimiento.…”

Screening of Beta Satellite Associated DNA-A Chili Leaf Curl Virus from Maharashtra

“…C hilli leaf curl disease is the most important constraint on Chilli production in India (Roy et al, 2023). Chilli (Capsicum annum L.) is an important high commercial value cash crop grown all over globe (Verma et al, 2022). Chilli leaf curl disease (ChiLCD) is caused by a cluster of related begomovirus species including Geminiviridae family ( Jeyaraj 2023).…”
