“…High heritability indicates less environmental influence in the observed variation (Eid, 2009). Broad-sense heritability (h 2 bs) only indicates whether or not there is sufficient genetic variation in a population, which implies whether or not a population will respond to selection pressure (Gatti et al, 2005;Milatovic et al, 2010;Ullah et al, 2012). High h 2 bs was recorded in all the traits, except for mean fruit weight in the early planting season.…”

Genetic variability in a crop population is important for successful plant breeding. Sixteen cucumber (Cucumis sativus L.) genotypes were evaluated in the early and late planting seasons to estimate the magnitude of their genetic variability and heritability. Genotypes were also classified into groups based on the performance and determination of the highest discriminating trait that accounted for greater variability using cluster analysis and principal component analysis (PCA), respectively. The measured agronomic traits were vine length, number of branches, number of leaves, and leaf area 8 wk after planting, days to flower initiation, days to 50% flowering, number of staminate flowers per plant, number of pistillate flowers per plant, fruit length, fruit girth, fruit weight per plant, number of fruits per plant, mean fruit weight, and total fruit yield ha -1 . A high coefficient of variation was recorded for most traits in both seasons and high variability was found among genotypes. High broad-sense heritability was associated with all the traits in both seasons, except for mean fruit weight in the early planting season and fruit girth, mean fruit weight, and total fruit yield in late planting season. Cluster analysis and its comparison of means showed that 'Beit Alpha', 'Ashely', 'Straight 8', and 'Sumter' from cluster F in the early planting season and 'Beit Alpha' and 'Ashely' from cluster E in the late planting season expressed the best agronomic traits and yield potentials. Hence, selection for any trait would favor genotypes in these clusters. Principal component analysis involved vine length as the most discriminating trait that accounted for greater variability in cucumber in both the early and late planting seasons, and it should be considered in cucumber improvement programs.

“…In order to improve its oil quality, a genetic crossing was made [18] between Chemlali Sfax (female or seed stock) and other varieties (autochthonous and introduced) well known by their superior fatty acid composition to that of Chemlali Sfax [16]. Studies of genetic variability, heritability and correlation between properties can show the extent to which certain traits are genetically determined and which of them have the greatest importance in the selection and creation of new cultivars [19].…”

The fatty acid (FA) composition of 540 Tunisian virgin olive oil hybrids (VOO) were classified by principal component analysis (PCA). Pearson correlation between FA variables revealed an inverse association between C18:1 and C18:2; C18:1 and C16:0, while C16:0 and C16:1 were positively correlated. PCA yielded five significant PCs, which together account for 79.95% of the total variance; with PC1 contributing 36.84% of the total. Eigenvalue analysis revealed that PC1 was mainly attributed to C18:1, monounsaturated fatty acids (MUFA) and the ratios oleic/linoleic (O/L) and monounsaturated fatty acids/polyunsaturated fatty acids (MUFA/PUFA); PC2, by C16:0, saturated fatty acids (SFA) and the palmitic/linoleic ratio (P/L); PC3 by C18:2 and C22:0, PC4 by C18:0 and PC5, by C17:1. Then, PCA analysis indicated that in addition to C16:0, C18:0, C18:1, C17:1, and C22:0, MUFA, SFA and the ratios O/L, P/L and MUFA/PUFA were determined to be the main factors responsible for the olive oil hybrids discrimination.

“…It was reported that the final fruit set for a successful controlled pollination can be between 10%-20% (Hesse, 1975;Topp et al 2008). Milatovic et al (2010) found that the rates of the average initial and final fruit set by open-pollination in forty peach cultivars were 73% and 42% respectively. The fruit set by selfpollination in peach is usually between 15% and 20% (Nyeki and Szabo, 1996) and the highest set is obtained from non-melting-flesh peach cultivars.…”

Abstract:In Turkey, peach breeding activities are quite inadequate. Only one breeding program to develop new peach varieties for fresh market and processing by controlled hybridization has been carried out in Ataturk Central Horticultural Research Institute. The present study was performed to evaluate fruit set rate, and a number of harvested fruit and stratified seed and germinated seed and seedling for each combinations and to determine the best parents to use in future crosses. Forty-two controlled crosses between ten peach varieties were made during 2008 and 2009 and total 32,922 flowers were pollinated. The full ripening fruits were harvested and hybrid seeds extracted. These seeds were stratified without endocarp at 4-5 °C for 40-90 days. The resulted seedlings were planted in an experimental orchard. Some problems including embryo and seed abortions, rosetting, multiple pistil and fungal infection occurred on fruits, trees and seedlings in the different developmental stages. The rates of fruit set were determined to be 78.27% and 73.10% for two years, respectively. Total 3,461 fruits were harvested and 2,730 seeds were stratified. The number of germinated seeds and resulted seedlings were 2,451 and 2,144, respectively. Our results showed that hybrid seeds should be stratified immediately after harvest to shorten breeding period and also stratification without endocarp can be lead the rosetting seedlings. Moreover, fluctuating temperature, not even frost, can cause to embryo abortions. Bayramic Tüysüzü, Sarı Papa, Vivian and Fortuna should be suggested as parent to obtain a large number of hybrid plants in a peach breeding program.
