to estimate combining ability and the model of gene action for some quantitative characters, 5 different rice genotypes were used for producing a half diallel hybrids. to consider 7 quantitative traits, hybrids and their corresponding parents were evaluated based on a randomized complete block design with three replications at the rice research station of amol, iran in 2007. mean squares regard...

Knowledge of relatedness among maize elite breeding genotypes is useful in planning crosses for hybrid and inbred line improvement assigning them into heterotic groups. This study investigated phenotypic genetic similarities or diversities between 7 flint lines (of common origin) adapted to the early growing regions created at ARDS Turda-Romania. They were studied per se traits two crossing sys...

Wild sweet cherry (Prunus avium) trees are abundant in the northern part of Turkey, including the Coruh Valley. We analyzed 18 wild sweet cherry genotypes collected from diverse environments in the upper Coruh Valley in Turkey to determine genetic variation, using 10 SSR primers. These SSR primers generated 46 alleles; the number of alleles per primer ranged from 3 to 7, with a mean of 4.6. The...

Strategies to manage bacterial wilt disease causing 64-100% yield loss have limited effectiveness. A 10×10 diallel mating design excluding reciprocals and self was employed in this study evaluate combing ability effects, heterosis, reaction 10 tomato parents. Genotypes AVTO1424 (11.87%), AVTO1429 (12.29%) AVTO1314 (13.53%) were found significantly lower incidence, demonstrating high level...

Many studies have shown that cytotoxic T lymphocyte antigen-4 (CTLA-4) gene variants are associated with several autoimmune diseases particularly type 1 diabetes. Due to the lack of consistent data for this association with type 2 diabetes (T2D), this study explored the possible influence of CTLA-4 gene polymorphisms at -1722 (T/C), -318 (C/T), and +49 (G/A) positions for susceptibility to T2D ...

The present study was carried out on snake gourd having seven diverse genotypes (TC 01, TC 05, 24, 33, 02, 46 and 53) used as parental lines their 21 crosses generated from 7 × half-diallel fashion at Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU) during March to June 2019 following RCBD with three replications. aim of the determine general combining ability (GCA) specific (...

The study was carried out to determine the physical, chemical and cooking characteristics among parents used in crosses their F1 hybrids derived from crosses. Parameters assessed include grain lengths of paddy, width length by ratio milled rice, milling recovery, water absorption rate on cooking, cooked elongation weight rice dimension, textual appearance after aroma. Results obtained were anal...

BACKGROUND & OBJECTIVES Chronic pancreatitis is progressive and irreversible destruction of the pancreas. Matrix metalloproteinase-7 (MMP-7) is a secreted matrilysin, which contributes to angiogenesis and breakdown of basement membranes of pancreatic tissues. The present study was aimed to investigate the association of MMP-7 -181A/G (rs11568818) gene promoter polymorphism in patients with chro...

Maize (Zea mays L.) is the most important cereal crop on which many smallholder farmers in sub-Sahara Africa (SSA) depend as a sole source of calories, proteins, and vitamins. However, conventional maize deficient two essential amino acids, lysine, tryptophan. Thereafter, Quality Protein (QPM) developed to combat protein malnutrition. In SSA low soil nitrogen also limiting factor production pro...

ABSTRACT Knowledge of the combining ability genotypes, genetic diversity, and heterosis play paramount role in obtaining double-cross hybrids with high productivity. This study was aimed at evaluating these parameters tomato genotypes using partial diallel crosses among commercial single-cross hybrids, which verified possibility for purposes. Tomato included 15 their genitors, two as checks. Of...
