Heterosis has been widely used in agriculture to increase yield and to broaden adaptability of hybrid varieties and is applied to an increasing number of crop species. We performed a systematic survey of the extent and degree of heterosis for dry biomass in 63 Arabidopsis accessions crossed to three reference lines (Col-0, C24, and Nd). We detected a high heritability (69%) for biomass producti...

Although most discussions today start from the assumption that the secular rise in IQ must be environmental in origin, three reasons warrant giving the genetic phenomenon heterosis a closer look as a potential cause. First, it easily accounts for both the high heritability and low shared environmental effects seen in IQ, findings that are difficult to reconcile with environmental hypotheses. Se...

to study the nature and magnitude of gene effects, heritability and number of effective factors for grain yield and some yield components in rice, six generations viz., p1, p2, f1, f2, bc1 and bc2 were prepared from the crosses of shapasand × irfaon-215 and irfaon-215 × saleh and grown in a randomized complete design with three replications. results of analysis of variance showed significant di...

In this study, three commercial fresh bean cultivars (SF08/03, Ribera and Java) two pole-type lines (Mor Toparlak Beyaz Toparlak) were hybridized (20 hybrid combinations) in accordance with full-diallel analysis method 2016. F 1 generations parents grown fully-automated plant breeding greenhouse of Selcuk University 2017. Measurements, counts, weightings analyses formed to determine height, pod...

Twenty one F2 progenies derived from a 7×7 diallel crosses along with parents were evaluated for grain yield, flowering and maturity time. Due to significant genotypic effects for all traits, genetic analyses were performed on F2 progenies including analyses of combining ability and genetic components. The Analysis of variance revealed that both additive and non-additive genetic effects were in...

Heterosis and combining ability are two important considerations in the utilization of heterosis, which can be used to generate excellent hybrid resource candidates is very conventional breeding. In this study, ability, heritability, heterosis eight major agronomic traits were analyzed 10 tomato parents 45 crosses between them. As well as TY-301, a recognized official variety that currently sel...

The use of heterosis has considerably increased the productivity of many crops; however, the biological mechanism underpinning the technique remains elusive. The North Carolina design III (NCIII) and the triple test cross (TTC) are powerful and popular genetic mating design that can be used to decipher the genetic basis of heterosis. However, when using the NCIII design with the present quantit...
