“…of fruits/ plant (97.09%, 84.22%), fruit yield per plant (96.86%, 67.95%) indicating strong influence of additive gene action and phenotypic selection is effective for these traits. Analogous observations were found by Lekshmi and Celine (2017) [3] and Ritonga et al, (2018) [6] . The knowledge about the nature and level of inter-relationship of yield and other components is very valuable because selection based on one trait may directly or indirectly affect the performance of another trait.…”

“…These high estimates indicate ample scope for enhancement of these traits through simple selection. High degree for PCV and GCV was reported by Lekshmi and Celine (2017) [3] and Panchbhaiya et al, (2018) [4] . Moderate level of GCV and PCV was seen in plant height at 60 DAT ( 17.61%, 18.67%), polar diameter of fruit ( 16.51%, 17.86%), days to first fruiting (15.91%, 16.56%), days to first flowering (15.58%, 16.89%), days to 50% flowering (15.14%, 16.39%), total soluble solid (13.63%, 13.90%), equatorial diameter of fruit (13.00%, 14.16%) and node to first flowering (11.15%, 12.75%).…”

“…The moderate estimates suggest that direct selection for these traits should be considered cautiously. Moderate estimates for GCV and PCV were reported by Lekshmi and Celine (2017) [3] and Panchbhaiya et al, (2018) [4] . Low level of GCV and PCV was seen in days to first picking (4.49%, 6.81%).…”

The present study was carried out with fourteen genotypes of tomato at Polyhouse Complex, Department of Horticulture (Veg. & Flori.), BAU, Sabour during 2018-2019 to assess the genetic variability and character association for yield and attributing traits in tomato (Solanum lycopersicum L.) genotypes for protected conditions. The experiment was laid out in randomized block design with three replications. Data were recorded for sixteen morphological traits and five biochemical traits. The experimental results revealed considerable differences among the genotypes for all the traits except titratable acidity and βcarotene. Higher phenotypic and genotypic coefficients of variation (PCV and GCV) were observed for no. of flowers/truss, no. of locules/fruit, no. of fruits/truss, fruit yield/plant, no. of fruit/plant, average weight of fruit, final plant height, titratable acidity, lycopene, ascorbic acid and β-carotene indicating phenotypic selection for these traits was effective for enhancement. High heritability together with high genetic advance as % of mean was observed in all traits except days to fruit picking. Based upon correlation and path coefficient analysis characters like no. of flower /truss, equatorial diameter, pericarp thickness and no. of fruit /plant could be reliable selection parameters for evolving high yielding genotypes.

“…Hybrid CLN2126×CLN1314G was significantly superior because of its genetic makeup and said the combination had a maximum number of fruits per plant, nodes per plant, and plant height; and minimum inter-nodal length and was early in flowering and fruiting. Such kind of genetic differences for marketable fruit yield and other plant characters in different tomato hybrids had also been reported (Arora et al, 2006;Chernet et al, 2014;Ahmad et al, 2016;Lekshmi and Celine 2017;Prakash et al, 2019).…”

“…The significant increase in fruit number might be due to the reason this hybrid combination was early in fruiting and its plant height was also maximum than others. Earlier researchers (Prajapati et al, 2015;Kumar and Singh 2016;Thapa et al, 2016;Lekshmi and Celine, 2017), also mentioned maximum number of fruits plant -1 due to these reasons.…”

A study was conducted to estimate genetic variability among horticultural traits and to evaluate these hybrids for protected environmental cultivation during spring-summer season, 2019 (April-September). Twelve hybrids of tomato were evaluated under modified naturally ventilated poly-house at the Vegetable Research Farm, Department of Vegetable Science and Floriculture, Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya following Randomized Complete Block Design (RBD) with three replications, Palampur, Himachal Pradesh, India. Based on the mean performance, hybrid CLN2126×CLN1314G was found promising for yield plant-1 (4.37 kg) yield m-2 area (26.24 kg), TSS (6.53 °B), days to 50% flowering (26.66 days), days to first picking (67.33 days), number of fruits per plant (64.01), inter-nodal length (17.71 cm), number of nodes plant-1 (16.70 nodes) and plant height 316.87 cm). So, an ideal plant type producing a higher yield per plant will be the one having traits like a higher number of fruits per plant, and lesser days to first picking. It is concluded that the hybrid combination CLN2126×CLN1314G is promising for these traits. This can be included for multi-locational testing in different agro-climatic zones of Himachal Pradesh under protected environment.

Abstract. Sahid ZD, Syukur M, Maharijaya A. 2020. Genetic diversity of capsaicin content, quantitative, and yield component in chili (Capsicum annuum) and their F1 hybrid. Biodiversitas 21: 2251-2257. Chili (Capsicum annuum L.) is one of the horticultural plants that have many benefits. The benefit of chili was determined by pungency level of its fruit. Pungency level of the chili is due to the capsaicin content in fruit. Information about the genetic diversity of capsaicin is still rarely available. The aims of this study were to obtain diversity information on quantitative, yield component, and capsaicin content, and to analyze the correlation among chili genotypes based on their morphological characters. This study used Randomized Complete Block Design with three replications. The genetic material used in this study consisted of 21 genotypes consisting of 6 genotypes of chili elders and 15 hybrid F1 genotypes resulting from their crossing. Six genotypes of the chili parents are C5, F6074, F9160291, Yuni, Bara, and Giant. 15 hybrid F1 genotypes used in this study are C5 x Bara, C5 x F6074, C5 x Yuni, C5 x Giant, C5 x F9160291, Bara x F6074, Bara x Yuni, Bara x Giant, Bara x F9160291, F6074 x Yuni, F6074 x Giant, F6074 x F9160291, Yuni x Giant, Yuni x F9160291, and Giant x F9160291. The observation was made on the variables of quantitative, yield, and capsaicin components on chili. The results showed that the highest capsaicin content only was found in Bara x F9160291. The results of scatterplot analysis showed that the highest capsaicin and yield component was found in BaraxF6074 and C5 x Yuni genotype. The results of cluster analysis showed that chili was clustered into three color groups. The character of capsaicin content is negatively correlated and very different from fruit weight, fruit diameter, fruit length, thick fruit flesh, total amount of fruit per plant, and fruit weight per plant.
