Genetic variability, heritability and genetic advance for various quantitative and qualitative traits in Chilli (Capsicum annuum L.)

Abstract

Genetic variability, heritability and genetic advance for different quantitative and qualitative characters were studied in 64 genotypes of chilli. The study indicated the existence of considerable amount of genetic variability for all the traits under study. Analysis of variance revealed significant differences among genotypes for almost all the traits studied. The maximum range was recorded for fruit yield per plant (150-900 g) followed by vitamin-C content at red ripe stage (35.50 -207.17 mg/100g), vitamin-C content at green stage (24.93-195.83 mg/100g), capsanthin content (39.58-180.35ASTA units, number of fruits per plant (21.32-100.27) and plant height (50.20-105.00cm). The highest phenotypic and genotypic coefficients of variability were observed for average fruit weight followed by seed yield per plant, average seed weight per fruit, number of fruits per plant, fruit yield per plant and fruit diameter. In general the phenotypic coefficients of variation (PCV) were slight higher than genotypic coefficients of variation GCV), which indicates the minor role of environment in the expression of traits under observation. The estimates of heritability in broad sense was high for all the characters. The present investigation indicateds a great scope of in the improvement of these traits as these characters in general possessed high estimates of heritability coupled with high genetic advancement except for days to first fruit set, days to first green fruit harvest, days to first ripe fruit harvest and dry matter content (high heritability but moderate genetic gain) indicating the preponderance of additive gene action for control of these traits.

Genetic Variability Studies in Chilli (Capsicum annuum L.) Genotypes under the Mid Hill region of Himachal Pradesh, India

“…High heritability was observed for all the traits considered in the study Similar results on high heritability have also been reported in chilli by Chattopadhyay et al (2011) for days to 50 per cent flowering, green fruit length and girth, no of fruits per plant, green fruit yield per plant, dry fruit yield per plant, ascorbic acid content, oleoresin content and capsaicin content, Zehra et al (2017) for days to first green fruit harvest, days to first ripe fruit harvest, plant height, fruit length, fruit diameter, average fruit weight, number of fruits per plant and cap-saicin content.…”

Penampilan Fenotipik, Keragaman, dan Heritabilitas Sembilan Genotipe Teh [Camellia sinensis (L.) O. Kuntze]

“…Nilai koefisien keragaman genotipe dapat memberi informasi mengenai keragaman genotipe dari suatu tanaman sehingga dapat diketahui tingkat keluasan dalam pemilihan genotipe. Melalui informasi heritabilitas, pemulia dapat menentukan sejauh mana intensitas seleksi yang dilakukan untuk memisahkan pengaruh lingkungan terhadap fenotipe suatu tanaman (Zehra et al, 2017).…”

Pewarisan Karakter Hasil dan Komponen Hasil pada Dua Populasi Persilangan Cabai Rawit Hijau (Capsicum annuum L.)

“…Heritabilitas juga digunakan untuk menentukan sejauh mana suatu karakter dapat diwariskan dari tetua kepada turunannya. Melalui informasi heritabilitas, memungkinkan pemulia dalam menentukan sejauh mana intensitas seleksi yang dilakukan untuk memisahkan pengaruh lingkungan terhadap fenotipe suatu tanaman (Zehra et al, 2017). Yunandra et al (2017) melaporkan bahwa karakter bobot buah per tanaman pada cabai memiliki heritabilitas arti sempit sedang, sedangkan karakter jumlah buah per tanaman memiliki heritabilitas arti sempit rendah.…”

“…Hal ini mengindikasikan peranan faktor genetik lebih besar dibandingkan faktor lingkungan dalam mempengaruhi penampilan suatu tanaman dan sifat-sifat tersebut dapat terwariskan pula pada generasi selanjutnya. Beberapa penelitian juga menunjukkan karakter hasil dan komponen hasil memiliki nilai heritabilitas arti luas tinggi, yaitu karakter bobot buah per tanaman (Adday, 2016), jumlah buah per tanaman (Hastuti et al, 2016), bobot per buah (Singh et al, 2017), umur panen, dan panjang buah (Zehra et al, 2017).…”
