“…Fruit yield plant -1 of tested hybrids of bell pepper in Korea ranged from 1194.0 g to 2907.0 g [35]. Matsunaga and coauthors [36] suggested that an inbred 'Sweet Pepper Parental Line Nou-1' has been used as a seed parent for F1 hybrids of bell pepper. In a study, Sood and Kumar [37] had observed the range of fruit yield plant -1 from 172.66 g to 359.33 g, and fruit length from 4.42 cm to 10.11 cm, and reported that the lines 'EC-464107', 'EC-464115', and 'Kandaghat Selection' were promising parents.…”

One nuclear male sterile (NMS) line of chilli pepper and eight elite inbred lines of bell pepper were evaluated in a line × tester mating design to project heterotic F1's through studying plant growth and yield performance of developed hybrids in relation to phenotypic distance between their parental lines. Hybrids and their parental lines were grown and evaluated under poly-net house conditions at the Punjab Agricultural University, Ludhiana, India during the years 2017-2019. Pooled over the year, mean squares (MS) due to genotypes was recorded significant (p=0.05) for all the traits studied, suggesting that there existed significant differences among the genotypic means that included nine parental lines and their eight F1 hybrids. The MS due to the G × Y interaction effects were also significantly different for plant growth and fruit traits, indicating differential response of each genotype in the year. On the basis of heterotic performance, the hybrids namely MS-12 × PAU SM-31 had positive significant mid-parent heterosis (MPH) for total fruit yield plant -1 (96.68**), number of fruits plant -1 (51.98**), pericarp thickness (47.91**), fruit length (25.77**), and plant height (63.35**). Apart from this cross-combination, the hybrids MS-12 × PAU SM-3 and MS-12 × PAU SM-9 also depicted MPH for total fruit yield plant -1 (71.22** and 50.64**), fruit length (41.98** and 68.09**) and number of fruits plant -1 (27.60** and 44.73**). Based on better parent heterosis (BPH), the hybrid MS-12 × PAU SM-HIGHLIGHTS  The effect of phenotypic distance between parental lines on the yield of C. annuum var. annuum × C. annuum var. grossum F1 hybrids was assessed. Simultaneously, the target of the research was transferring of the GMS ms10 gene from hot pepper to heat tolerant bell pepper inbreds. Over the BP, the hybrid MS-12 × PAU SM-31 was found to be superior in respect of total fruit yield plant -1 and pericarp thickness. 2 Rani, M.; et al.
