Selection progress is one of the parameters success in a plant breeding program. with pedigree approach made early generation intended to increase mean value and reduce variance selected population. This study aimed determine selection response from F2 F3 different locations, obtain transgressive segregant genotypes. The was conducted August 2018 April 2019 at IPB Tajur II Experimental Field (3...

Tomato (Solanum lycopersicum L.) is an important vegetable crop and acts as model plant for fruit development studies. Besides that, post-harvest damage is a devastating phenomenon often associated with ripening process in tomato which in turn leads to greater yield loss. Understanding the genetics, molecular and biochemical pathways is the key to overcome the existing situation. In th...

Are evolutionarily entrenched phenotypes highly constrained developmentally? We explored this question in the case of the uniramous appendages of fruit flies. We created bi- and polyramous antenna/leg combinations in four different genotypes. Each genotype consisted of two relevant mutations. We suggest that not all entrenched characters are strongly constrained by developmental processes and t...

The first step in walnut breeding programs is to identify and evaluate superior genotypes of fruit trees. Hence, there are various walnut breeding programs in various areas of Iran. A study aimed to evaluate the morphological and chemical characteristics of selected superior genotypes of walnut was conducted in the Shahroud region in 2011-2012.  The following genotypes were selected in this stu...

ABSTRAKCabai rawit (Capsicum frutescens L.) merupakan tanaman hortikultura penting. Produktivitas cabai terus meningkat, tetapi masih di bawah potensi hasilnya. Alternatif untuk meningkatkan produktivitas dan kualitas adalah dengan perakitan varietas unggul. Varietas unggul dapat dirakit apabila tersedia plasma nutfah atau sumberdaya genetik yang mempunyai karakter sesuai sifat diiinginkan. Unt...

Mapping studies using populations with introgressed marker-defined genomic regions are continuously increasing knowledge about quantitative trait loci (QTL) that correlate with variation in important crop traits. This knowledge is useful for plant breeding, although combining desired traits in one genotype might be complicated by the mode of inheritance and co-localization of QTL with antagonis...

Palm fruit juice (PFJ) containing oil palm phenolics is obtained as a by-product from oil palm (Elaeis guineensis) fruit milling. It contains shikimic acid, soluble fibre and various phenolic acids including p-hydroxybenzoic acid and three caffeoylshikimic acid isomers. PFJ has also demonstrated beneficial health properties in various biological models. Increasing concentrations of PFJ and diff...

Mutualisms are known to be genetically variable, where the genotypes differ in the fitness benefits they gain from the interaction. To date, little is known about the loci that underlie such genetic variation in fitness or whether the loci influencing fitness are partner specific, and depend on the genotype of the interaction partner. In the legume-rhizobium mutualism, one set of potential cand...
