One of the most important purpose in breeding program is increasing grain yield per hectare. Using selection indices is the most effective methods of selection for simultaneous improvement of grain yield and related traits, which often have a quantitative inheritance. In this study, 29 rice genotypes (9 parents and 20 progenies) were evaluated. The numbers of filled grains in panicle and panicl...
Identification of easily measured physiological traits contributing to yield under specified environmental conditions would benefit genotypic selection for grain sorghum. A field experiment was conducted to determine broad-sense heritability and expected genetic advance, and to examine the relationships of grain yield with 11 physiological traits related to developmental periods, vegetative gro...

Two F2 populations segregating for biomass yield and forage quality traits were developed from two separate crosses of tropically adapted maize inbred lines. The parental, F1 generations both evaluated to estimate broad sense heritability, genetic advance correlations these suggest the best as selection criteria towards breeding with high quality.In Cross 1, trait highest broad-sense heritabili...
Compared with morphological and life history traits, quantitative genetic variation of metabolic and related traits in animals has been poorly studied. We used flow-through VCO(2) respirometry and simultaneous activity measurement on nymphs of the sand cricket (Gryllus firmus) from inbred lines to estimate broad-sense heritability of four metabolic variables. In addition, we measured a number o...
The objective of this study was to estimate heritability, heterosis, and genetic parameters involved in the control of forage yield and quality in kenaf populations, using analysis of generation means. Two crosses were used; Cuba 2032×Accession 75-71 and IX51×Everglade 41. Experimental material comprised of P1 and P2, their F1 and F2 and BC1P1 and BC1P2 generations. The effects of generations w...
To determine gene action and heritability of grain yield related traits in rice, six rice varieties including Hashemi, Vandana, Kadous, Hassani, Shahpasand and IR36 were crossed in a diallel design in 2010. The parents and seeds of F1 generation (36 genotypes) were grown in a completely randomized block design with three replications at the Research Field of the Rice Research Institute of Iran-...
