...bility, heritability and genetic advance for important attributes in Brassica napus using 10 parental lines and their 21 F4 populations. Significant differences were observed among genotypes, parents, F4 populations and parents versus F4 populations for days to 50% flowering, days to maturity, plant height, primary branches plant-1 and main raceme length. Among parents, CA2, DH8, DH4, CA4 and DH6 performed bet...

...imation of heritability, genetic advance and association of yield and yield related traits in wheat. For all the studied traits, mean squares showed the presence of significant variation (p≤0.01) among the genotypes. Heritability estimates were observed high (h2˃0.60) for all the traits. The highest heritability (0.93) was noticed in plant height followed by flag leaf area (0.89). The values of genetic advance were r...

...gh heritability with low genetic advance was estimated for days to maturity, while moderate to high heritability coupled with genetic advance was recorded for other yield related traits. Correlation analysis showed that grain yield had strong positive phenotypic and genetic correlation with heading, maturity, flag leaf area and biological yield. Spring wheat genotype SM12 had best performance for grains spike-1 and grain wei...

...ariations, heritability, genetic advance and correlation among 20 F1 hybrids and 9 parents in upland cotton. Line × tester mating design was deployed to develop crosses and 29 cotton genotypes were field planted in randomized complete block design (RCBD) in three replications to assess the genotypes for plant height (cm), number of sympodial branches, number of monopodial branches, seed cotton yield (g), number of bolls, boll weight (g), lint percentage ...

...eritability and expected genetic advance reflected that all attributes were governed by additive genes and early phenotypic selection for their improvement might be effective. Five principle components (PCs) were depicted having Eigen value >1 and cumulative variability of 78.66%; PC1 (37.19%), PC2 (12.94%), PC3 (11.62%), PC4 (9.60%) and PC5 (7.32%) of variability. The attributes of significance depicted in PC1 were seed cotton yield, seed index, lint index...

...nbsp;Heritability (b.s), genetic advance, phenotypic and genotypic variance for different quantitative traits is important in determining the effectiveness of selection. In this study the potential effectiveness of selection in parents and their F2 and F3 progenies of Gossypium hirsutum for plant height, sympodia/ plant, bolls/plant, boll weight, seed index and seed cotton yield/plant was determined. It was found that all the populations alongwith parents diff...

...onding high estimates of genetic advance in percent of mean (17.23 and 18.33) for these traits indicated the predominance of additive gene effects. Mass selection based on these additively controlled traits is suggested for improvement of yield. Plant height, number of bolls plant-1 and 1000-seed weight showed genetic advance of 7.96, 8.85 and 17.23 % respectively with the prospects of improving seed yield up to the level of...

GENETIC VARIABILITY STUDIES IN BREAD WHEAT (TRITICUM AESTIVUM L.) ACCESSIONS
...y estimates and expected genetic advance were found for all the traits except chlorophyll concentration index, spike length and number of -1 spikelet spike which exhibited moderate heritability. Based on Euclidian dissimilarity distance, 65 wheat accessions were classified in to 6 different clusters. Maximum diversity was found in cluster 1 and cluster 4. This maximum diversity explains the better parental selection for future breeding programme.

High heritability coupled with high genetic advance indicated the effectiveness of selection in early generation for the improvement of these traits. Genotypes Faisalabad-2008 and line from Tajikistan (2S-3094) performed better for most of yield a...

Seed yield showed positive and significant genotypic and phenotypic correlations with clusters per plant (rg = 0.322), pods per plant (rg = 0.276), biological yield (rg = 0.470) and harvest index (rg = 0.264). These traits also showed high positive direct effe...

The results showed the existence of adequate genetic variability among the tested wheat genotypes. High PCV and GCV were found in grains spike-1, while highest broad sense heritability with inferior genetic advance was recorded for plant height....

Thirty-eight lines derived from F5 rice cross combinations along with their 8 parents were planted in a randomized complete block design (RCB) having three replications at The University of Agriculture, Peshawar during 2016 rice crop growing season. Data were taken on some of the morphological traits like number of days to heading (days), number of days to matur...

While, narrow sense heritability and genetic advance was lower for remaining parameters under both the environmental conditions which clearly specified that non-additive gene action was present. Results indicated that the said breeding material might be better suited for heterosis breeding...
