Abstract: An experiment was conducted during 2016-2017 at Vegetable Research and Demonstration Block of college of horticulture, VCSG Uttarakhand University of Horticulture and Forestry, Bharsar. The experiment was laid out in a Randomized Block Design (RBD) with three replications. Six diverse chilli lines viz. Byadgi Dabbi, Byadgi Kaddi, Arka Lohit, Arka Suphal, G-4 and Pant C-1 used as parents and were crossed in a diallel fashion (excluding reciprocals) to obtain fifteen cross combinations along with one check cultivar Arka Harita. Totally 22 genotypes were evaluated for biochemical traits. Among the genotypes studied, Pant C-1 (1.07%), Arka Lohit (0.72%), Arka Lohit × Pant C-1 (0.89%) and Arka Suphal × Pant C-1 (0.74%) recorded the highest capsaicin content and the lowest capsaicin content was recorded in Byadgi Dabbi (0.02%), Byadgi Dabbi × Byadgi Kaddi (0.03%). The highest ascorbic acid content among the entries recorded was 218.35mg/100g (Byadgi Dabbi), 197.84mg/100g (Byadgi Kaddi) and 223.17mg/100g (Byadgi Kaddi × Arka Lohit), 211.36mg/100g (Byadgi Dabbi × Pant C-1) and the lowest ascorbic acid content recorded was 111.73mg/100g (Arka Suphal), 120.12mg/100g (Pant C-1) and 115.01mg/100g (Arka Lohit × Pant C-1). From the above study, it was concluded that the cultivars viz. Byadgi Dabbi and Byadgi Kaddi × Arka Lohit have high ascorbic acid content and similarly Pant C-1 and Arka Lohit × Pant C-1 have high capsaicin content hence, these genotypes can be utilized for further crop improvement programmes at the same time such cultivars which also fetches high market price both in domestic and export markets.

Sixty three genotypes of chilli (Capsicum annuum L.) were evaluated at Horticultural Research Station, Lam, Guntur (Andhra Pradesh), India; to select the promising genotypes for qualitative traits viz. capsaicin content, total color value, oleoresin content, vitamin C, red carotenoids and yellow carotenoids. The analysis of variance revealed significant differences among the genotypes for all the six characters. Among sixty three genotypes, the highest ascorbic acid content was recorded for the genotype Aparna (223.22), while the lowest was observed in Phule Jyoti (43.99). The highest oleoresin content was recorded by the genotype LCA-724 (12.31) and the lowest in Pandava (5.17). The highest capsaicin content was recorded by the genotype Pusa Sadabahar (0.64), while the lowest was in G-4 (0.14). The maximum colour value was observed in the genotype LCA-713 (128) and the minimum in Aparna (20.58). The maximum per cent of red carotenoids was observed for genotypes LCA-357 and KT-1 (0.22), while the genotype Aparna had no red carotenoids. The maximum per cent of yellow carotenoids was observed for the genotype HC-28 (0.15) and the minimum for LCA-724 and LCA-620 (0.01).

The present experiment was carried out during spring summer season of 2014 at Vegetable Research Center of GBPUAT, Pantnagar (Uttarakhand) to estimate the performance of chilli genotypes for yield and qualitative traits in randomized block design with three replication. Observations were recorded on yield and various qualitative traits viz. number of primary branches, stem diameter, number of petals, days to 50% ripening, periferi of fruit, pericarp thickness, average fruit weight, number of seeds per fruit, weight of seeds per fruit, seed yield per plant, 100 seed weight and total dry fruit yield (q/ha) from five selected plants in each replication. There was found significant variation among all the genotypes for different characters under study. Maximum dry matter content was found in genotype PC 20131, oleoresin content in PC 20115 and Ascorbic acid content in PC 1. In case of fruit yield per plant genotype PC 20132 (89.79 g) produced maximum fruit yield.

Introduction Chilli (Capsicum annuum L.) known as universal spice and having various utilities as a vegetable, spice, condiment, culinary purpose, ornamental plant and having medicinal properties due to rich source of various phytochemicals and other compounds. Immature chilli fruit contain the phytonutrients ascorbic acid, carotenoids, rutin etc. As a medicine it is used as a counter irritant in lumbago, neuralgia, and rheumatic disorders. It has a tonic and carminative action. The enzyme isolated from chilly is used in the treatment of certain type of cancers. It has also acquired a great importance because of the presence of oleoresin, which permits better colour distribution and flavour in foods. India is the major producer, consumer, and exporter of chilli, contributing almost 36 percent of the world production. Chilli contributes about 33% of the total spice export from India and accounts for about a 16% share of the world spice trade. In India Andhra Pradesh rank first in chilli production followed by Tamil Nadu. In view of the changing of food habits and health conscious, food quality particularly perishables like fruits and vegetables is gaining importance since improved quality not only facilitates remunerative market price for the producer and also improves health of the consumer (Janki et al., 2015) [5]. There are many constraints for getting good production like unsuitable cultivars/hybrids, biotic and abiotic stresses, genetic drift in cultivars, and development of new races of pathogens, among several factors, lack of improved varieties is the main constraints for getting production. Studies on chilli genotypes revealed that great variation exists in ability to flowering, fruit set, yield and other qualitative attributes under different agro-climates (Rani, 1996 and Maurya et al., 2016) [13, 9]. Thus, the attempts towards improvement of yield coupled with quality characters in chilli have lot of significance which can increase the income of the farmer through premium price.
, VR-339, AKC-89/38, DC-16 and Punjab Lal) of chilli were crossed to derive 25 F 1 hybrids. The 35 genotypes (10 parents and 25 F 1 hybrids) were evaluated for yield and quality (capsaicin and oleoresin) traits. Highly significant correlation was observed between fruit yield per plant and average fruit weight (g). The direct and indirect effect on yield revealed that the maximum direct effect was exhibited by average fruit weight followed by number of fruits per plant via yield per plant. The crosses Pusa Jwala × VR-339, Pusa Jwala × DC-16 and Pant C-1 × VR-339 exhibited higher level of heterobeltiosis for most of the traits. The higher specific combing ability (SCA) for yield was obtained in crosses Kashi Sinduri × Punjab Lal followed by Pant C-1 × VR-339 and Pusa Jwala × VR-339. Among the hybrids, Pusa Jwala × VR-339 had higher yield as well as capsaicin content, moreover, Kashi Sinduri × AKC-89/38 exhibited highest oleoresin content. These best hybrids (Pusa Jwala × VR-339, Kashi Sinduri × Punjab Lal and Pant C-1 × VR-339) might be utilized for further chilli improvement programme.
