Pepper species of the genus Capsicum have been cultivated over centuries, producing both pungent and sweet fruit; the pungency is caused by alkaloids called capsaicinoids. Among the five cultivated species, Capsicum chinense is one of the most popular, being native to the Amazon basin. This species is characterized by a wide variety of fruit sizes, shapes and colors, with different capsaicinoid...

Most of the available results on optimal block designs for diallel crosses are based on standard linear model assumptions where the general combining ability effects are taken as fixed. In many practical situations, this assumption may not be tenable since often one studies only a sample of inbred lines from a possibly large (hypothetical) population. Recently Ghosh and Das (2003) proposed a ra...

The study examines the level of manifestation heterosis effect in hybrid populations, which increases efciency selection process winter wheat based on number grains main ear. 30 combinations were created using a complete diallel crossings scheme for six varieties soft with wheat-rye translocations (WRT): 1AL.1RS – Ekspromt, Zolotokolosa, Kolumbiia and 1BL.1RS Kalynova, Svitanok Myronivskyi, Leh...

The study aimed to show the best effect of general combining ability (GCA) and specific (SCA) for parents their hybrids studied traits. included two main successive seasons. In first season, cherry tomato pure lines were selected that introduced from Tomato Genetics Resource Center (TGRC) at University California, Davis in USA, 5 which most genetically Distant are (LA4451, LA4753, LA3334, LA122...

The objective of this study was to screen single nucleotide polymorphisms (SNPs) of the chicken lipoprotein lipase gene (LPL), using 545 F1 hybrids developed from 4×4 diallel crossing of four chicken breeds, and to analyze the associations between polymorphisms of the LPL and chicken fat deposition traits. PCR-SSCP was used to detect SNPs in LPL. Fifteen sets of primers were designed to amplify...

Combining ability analysis provides useful information for the selection of parents, in breeding program cucumber at Can tho, VietNam, as well related to nature and extent gene activities involved. Cucumberimprovement involves strategies enhance yieldpotential quality cucumber. Targeting improvement new varieties plants, combining abilities genetic parameters 12 traits estimated from full diall...

Background: Garden pea (Pisum sativum L. var. hortense) belongs to family leguminosae is an important legume vegetable grown throughout the world during cool season. It self pollinated pulse crop with chromosome number 2n = 2x 14. Based on genetic diversity its primary centre of origin Mediterranean region. used as fresh and processed frozen in India abroad. good source vegetarian protein (6.8%...

The phenotypic variation in osmotic adjustment (OA) capacity of five Bulgarian winter durum wheat genotypes and their progenies was determined using a modified method based on the measurement of seedling growth suppression after three-day exposure to osmotic stress induced by 1 mol/L sucrose. The genetic parameters of the studied trait in a diallel crossing scheme, including the selected genoty...

Fifteen genetically diverse parental genotypes of sunnhemp belonging to different geographical origin were assessed to evaluate general and specific combining ability of parents and cross combinations, respectively, for selecting the superior parent combination. For this, fifteen parents and their 105 F1s were grown in a Randomized Block Design (RBD) with three replications and data were collec...
