“…Sweet pepper (capsicum annuum L.) is an important remunerative vegetable with a high nutritional value throughout the world belongs to the family Solanaceae used fresh or dried. This plant is diploid and has 2n = 2x = 24 chromosomes (Jindal et al, 2019). Pepper has an international market that is consecutively increasing and world production has expanded greatly over the last decades.…”

Hybrid cultivars are commercially and economically important; hence, too much effort needed to improve the quality and quantity of hybrids. In this research project, general (GCA) and specific (SCA) combining ability of 32 doubled haploid (DH) lines of sweet pepper produced via microspore embryogenesis were evaluated. The DH lines were crossed with the top cross parent as the tester to evaluate general combining ability (GCA). Traits including morphological and yield-related characteristics to assess the general combining ability of lines were recorded and analyzed. The half-diallel mating crosses were performed using GCA based on the selected seven DH lines for SCA evaluation. Mean squares of GCA and SCA values were highly significant for most of the characters. DH55 line indicated the highest positive GCA for average yield per plant, moreover, the highest positive SCA was obtained for 55×64 hybrid. The ratio of \(\frac{MS \left(GCA\right)}{MS \left(SCA\right)}\) showed the non-additive gene actions in controlling all traits except fruit width and length and seed fresh weight. According to the results of specific combining ability of DH lines, four F1 hybrids were selected for new cultivar registration. The results obtained in the present study are applicable to release new F1- hybrids, which can be more reliable than those hybrids introduced by conventional selfing programs in sweet pepper due to 100% genetic purity of DH lines.

“…Although there are several reports of employing cytoplasmic male sterility (CMS) and genetic male sterility (GMS) in the chilli pepper, the system is still in the early phase of development. Moreover, when employing GMS for hybrid seed production, the segregation into male sterile and male fertile plants is commonly noticed, as is the difficulty of rouging plants with fertile pollens [14].…”

Chilli pepper is commercially cultivated as a spice and is also used for the extraction of a colouring agent. Here, we performed a diallel genetic study involving five chilli pepper varieties. Parents and their hybrid were evaluated for fifteen morphological and five biochemical traits over two crop seasons under open field conditions. Variation was recorded for all of the studied traits. Similarly, significant values for general combining ability (GCA) and specific combining ability (SCA) variance were obtained for all of the traits. The ratio of σ 2 SCA/σ 2 GCA indicates that non-additive gene effects were predominant for all the studied traits except for fruits plant −1 . Based on SCA effects, cross combinations P2 × P5, and P4 × P5 were determined excellent for flesh thickness, yield components and vitamin C. These hybrids are recommended for multilocation testing to assess their suitability for commercial cultivation. Overall, this work presents useful information regarding the genetics of important morphological and biochemical traits in chilli pepper.

“…Information on both NMS and CMS systems in pepper was reported and the prospects for their use in breeding for heterosis discussed [39]. Screening of C. annuum and C. baccatum accessions led to the discovery of new sources of Rf genes for male sterility [40].…”

The United States Department of Agriculture/Agriculture Research Service/National Germplasm System (USDA/ARS/NGS) plant germplasm collections contain more than 600,000 different accessions of 16,289 species, including virtually all the ethnic and specialty crops of interest to United States (U.S.) agriculture. These and additional collections of plant seeds and asexual propagules are maintained at various laboratories and facilities geographically dispersed in the U.S. including NGS and many public land grant university institutions. The majority of these species fall under the definition of “specialty” crops since their utility is either narrow in scope or has not been fully developed. This paper summarizes the status of “specialty” and ethnic crop species germplasm in the U.S. including where the collections are maintained and how they are being used.
