چکیده
Abstract This study intends to estimate the coefficient of repeatability for traits relating yield, so as infer what is minimum number evaluations required identify superior genotypes; verify adaptability and stability; predict genetic gains; select best families in S1 progenies Psidium guajava. Families were obtained by means self-fertilization genotypes (full sibs) from guava tree breeding program UENF. The experiment was implemented at Experimental Station Ilha Barra do Pomba, municipality Itaocara-RJ. In this case, an experimental randomized block design used with 18 inbred families, three replicates, ten plants per plot. Inbred evaluated harvests regarding fruit weight, fruits plant, total yield. It then conducted analysis repeatability, adaptability, stability Selegen/REML/BLUP program. Repeatability values show that performance constant among measurements, suggesting need perform only selection genotypes. There agreement on choice 1, 4, 6, 12 most yielded, adaptable, stable evaluated.

متن کاملMixed models for selection of Jatropha progenies with high adaptability and yield stability in Brazilian regions.
The aim of this study was to estimate genetic parameters via mixed models and simultaneously to select Jatropha progenies grown in three regions of Brazil that meet high adaptability and stability. From a previous phenotypic selection, three progeny tests were installed in 2008 in the municipalities of Planaltina-DF (Midwest), Nova Porteirinha-MG (Southeast), and Pelotas-RS (South). We evaluate...
متن کاملGlycaemic evaluation of Psidium guajava in rats.
BACKGROUND & OBJECTIVE Many plant polysaccharides exhibit hypoglycaemic effect. Though the fruit of Psidium guajava is known to contain free sugars, the fruit extract showed hypoglycaemic effect in alloxan treated mice and human subjects. The present study was aimed to determine the glycaemic potential of P. guajava fruit peel extract on blood glucose level (BGL) of normal and streptozotocinind...
