Eighty-nine germplasm of rice (Oryza sativa L.) along with four checks were evaluated in a well-prepared field to assess the genetic variability, heritability, and advance for different characters under irrigated conditions Augmented Block Design. In this study, analysis variance revealed highly significant or all 13 except non–significant 1000- grain weight. High moderate broad sense heritabil...

Peach is a temperate fruit species that cultivated under various edaphoclimatic conditions all over the world. In Brazil, in early 1950s, peaches were planted only Sao Paulo state and Southern states, harvest period was restricted to 15 days. Currently, mainly due peach breeding programs, it subtropical areas even high altitude tropical areas, with of 100 Knowledge genetic, phenotypic environme...

Characterization and conservation of germplasm is a critical step toward the genetic improvement crop. This study assessed variation in 257 common bean genotypes which included 207 accessions obtained National Gene Bank Kenya, 33 from Kenya Agricultural Livestock Research Organization (KALRO), 13 landraces collected farmers’ fields four commercial varieties for various agronomic traits. T...

Genetic improvement of seed vigour and emergence of yellow-seeded flax (Linum usitatissimum L.) is important to have a good stand establishment, since they are negatively affected by yellow seed colour. This study was conducted to investigate genetic variation, broad-sense heritability and expected genetic response to selection for germination, seed vigour and field emergence. Sixteen genotypes...

Abstract The aims of this study were to estimate the diversity doubled haploid population winter oilseed rape ( Brassica napus L.) in terms yield, yield structure and seed colour, determine correlation between studied traits their heritability, select best yellow-seeded genotypes. We 44 haploids, obtained from F 1 hybrids a cross black-seeded DH H 2 -26 line Z-114 line, as well parental forms. ...

A model of genotype-environment interaction in quantitative traits is considered. The model represents an expansion of the traditional additive (first degree polynomial) approximation of genotypic and environmental effects to a second degree polynomial incorporating a multiplicative term besides the additive terms. An experimental evaluation of the model is suggested and applied to a trait in D...
