“…In the previous studies on chilli evaluation, it has been reported that the hybrids or genotype performance varies based on agro-climatic conditions of the location. For instance, in different studies, the outperforming genotype for the Ludhiana region was PL-412 (Dhaliwal et al 2019) in the North India plains, and for the Coimbatore region was EC739328 (Manikandan et al 2016) of southern part of India in C. annuum. Further, the performance of hybrids for green and dry red fruit segments of the chilli can vary depending on the climate, season and location.…”

Chilli (Capsicum) is in high demand as a vegetable and spice throughout the world. Fruits have wider applications in the food, phytogenic feed, cosmeceutical and pharmaceutical industries. As surge for their uses is increasing, there is a need to develop F1 hybrids to enhance yields with tolerance/ resistance to major threatening diseases. The present investigation was carried out to study the diversity of morphometric, fruit quality and yield traits, and their reaction to chilli leaf curl disease among fourteen CGMS based high yielding F1 hybrids developed at ICAR-IIHR, Bangalore, India. The hybrids Arka Nihira, Arka Yashasvi, H-25, H-26, and Arka Tanvi excelled for the majority of the evaluated traits in terms of yield enhancement. The yield increment potential in these hybrids is attributed to higher morphometric, fruit biometric and physiobiochemcial traits (NDVI and chlorophyll content). In relation to the local check, hybrid Arka Nihira exhibited enhanced green fruit yield by about sixty-two percent. The cluster plot partitioned these hybrids into four primary groups, revealing genetic similarities and differences among the hybrids. Further, character association indicates that the traits such as days to 50 percent flowering, plant spread, fruit girth, and the number of fruits per plant can be leveraged as indirect selection indices for green fruit yield while selecting a commercial hybrid cultivar in chilli breeding programs. As a result, the hybrids Arka Nihira and Arka Tanvi, in particular, have the potential to be commercial cultivars in terms of yield, agronomic characteristics, and leaf curl disease tolerance in shallow basaltic soils of the Deccan plateau of India.

Drought is an important abiotic stress factor that severely affects plant growth, especially in arid and semi-arid regions. The effect of limited irrigation on plant growth and its response depending on growth stages is critical for agriculture in these regions. This study was conducted to understand how different pepper species (C. annuum L. and C. chinense Jacq.) respond to drought conditions. Plants were subjected to four different irrigation regimes (100% field capacity (FC), 75% FC, 50% FC, and 25% FC) and three developmental stages (S1: 20 days after flowering, S2: 40 days after flowering, and S3: 60 days after flowering). The effects of drought on plant morphological growth, photosynthetic pigment content in leaves, phytochemical components [total phenolics (TPh), total flavonoids (TFv), and total antioxidant activity (TAa)], proline (PRL), protein (PRO), malondialdehyde (MDA), and activities of major antioxidant enzymes [catalase (CAT), superoxide dismutase (SOD), and peroxidase (POD)] were investigated. According to the results, drought had a negative effect on plant morphology and physiology of both species, and these effects differed between plant species. The amounts of phytochemicals, MDA, PRO, PRL, and antioxidant enzymes increased in higher percentages with increasing drought severity (especially at S2 and S3 growth stages) in C. annuum. Moreover, antioxidative enzyme activities were significantly higher in C. annuum with increasing stress severity, helping the species to overcome oxidative stress under drought conditions. In conclusion, the findings showed that C. annuum is a drought-tolerant species with much more stable morphological, physiological, and biochemical performances compared to C. chinense.
