    Line X tester analysis in pea (Pisum sativum L.): Identification of superior parents for seed yield and its components
    (ACADEMIC JOURNALS, 2008) Ceyhan, Ercan; Avci, Mehmet Ali; Karadas, Serdar
    This research was carried out to investigation the genetic structure of the 24 F-1 pea hybrids established from eight exotic female lines and three local winter hardiness male testers, to determine parents showing general combining ability (GCA) and determine crosses showing specific combining ability (SCA.), and to evaluate the heterosis. Broad genetic variability was observed among the genotypes. Estimates of variance due to GCA and SCA and their ratio revealed predominantly non-additive gene effects for all studied traits. While PS9830S329 (female) and H (male) were the best general combiners among the parents, PS9830S329 x B-12 was the best cross for seed yield. Hybrids generally showed greater yield potential than their parental genotypes. Heterosis was observed in some hybrids for each trait studied.

    Relationships Between Protein Content and Chemical Compositions of Local Dry Bean (Phaseolus vulgaris L.) Genotypes Grown in Turkey
    (ASIAN JOURNAL OF CHEMISTRY, 2009) Harmankaya, Mustafa; Karadas, Serdar; Palta, Cetin; Ceyhan, Ercan
    In present study, bean local genotypes grown in the Central Anatolian Province of Turkey have been analyzed to determine and compare their protein and mineral contents. Statistically significant variations were found amongst the genotypes for all variables. The protein and minerals analyzed for all bean genotypes show that protein varies 18.33 to 23.67 %, potassium from 963.3 to 1140 mg/100 g, phosphorus from 310.9 to 423.9 mg/100 g, calcium from 125.1 to 322.0 mg/100 g, magnesium from 90.25 to 105.9 mg/100 g, sulfur from 136.6 to 181.3 mg/100 g, sodium from 25.47 to 45.17 mg/100 g, manganese from 1.70 to 3,27 mg/100 g, iron from 3.84 to 8.41 mg/100 g and zinc from 2.09 to 2.85 mg/100 g. Positive and significant relationships were found statistically between protein and potassium, protein and phosphorus, protein and magnesium, protein and sulfur and protein and iron. The results show that bean genotypes can serve as a significant source of protein and minerals to meet the demand of populations living in Turkey.
