“…This has important applications for the study of relations between molecular markers and agronomic traits, some of which include: the detection and analysis of potential in specific genotypes, collections of germplasm, identification of desirable alleles, and validation of candidate markers linked to quantitative traits (Gebhardt et al, 2004). Although the mapping of quantitative trait loci (QTLs) is well suited for detection of genes associated with the traits, it is labour intensive, while segregating population preparation is both time consuming and costly (Rakshit et al, 2010). In order to overcome these limitations, multiple regression analysis offers an appropriate method to identify markers associated with the trait.…”

To investigate the relationships between agronomic traits and molecular markers in sand plantain (Plantago psyllium), a set of 17 ecotypes collected in Iran were evaluated. Twelve ISSR primers were tested through multiple regression analysis to identify the marker-trait association between ISSR data and agronomic traits. Finally, the 12 primers amplified 129 fragments (loci) among ecotypes: 91 fragments (70.54%) of the 129 fragments showed polymorphism with an average of 7.58% per primer and the rate of this polymorphism ranged from at least 57.14% for UBC824 primer up to 54.62% for UBC813 primer. Polymorphic information content ranged from 0.27 (UBC814) to 0.41 (UBC813), with an average of 0.36. Stepwise regression analysis between the molecular data as independent variables and the studied traits as dependent variables was performed to identify informative markers associated with the agronomic traits. Seventy ISSR fragments were found associated with eight morphological traits. Some of ISSR markers were associated with more than one trait in multiple regression analysis that may be due to the pleiotropic effect of the linked quantitative trait locus on different traits or is linkage of different genes. However, for a better understanding of these relationships, preparation of a segregating population and linkage mapping are necessary. Also, these result could be useful in marker-assisted breeding programmes when no other genetic information is available.

Development of molecular markers from Indian genotypes of two Gossypium L. species

et al. 2013

Two genotypes of Gossypium hirsutum and four genotypes of G. herbaceum have been used to develop large‐scale molecular markers, especially SSRs and SNPs for their use in various molecular breeding programmes of cotton. A total of 1440 expressed SSRs and 2608 SNPs were identified from transcriptome of two genotypes of G. hirsutum. In addition, 10 971 SNPs were also developed from transcriptome of G. herbaceum, of which 4059 SNPs were transition and 6912 were transversion and there were 238 indels. This study added a total of 334 novel SSRs and 1847 novel SNPs in G. hirsutum and 10 947 novel SNPs in G. herbaceum to the public domain. We also validated a subset of 25 novel SSRs and 12 SNPs with five genotypes of G. hirsutum.

“…Such an association may be due to pleiotropic effects of the linked QTL on different traits. Closely linked QTLs affecting different traits may also lead to a single marker showing association with multiple traits that would be reflected in correlations between traits (Rakshit et al ). In our study, two markers were found to be associated with SH and SW. Three markers were correlated with TW.…”

This study aimed to investigate the correlation between marker polymorphism and growth traits in Pinctada fucata martensii. Five microsatellite markers (2PM206, 3PM10, 4PM34, 4PM50, and PM6) derived from expressed sequence tags were selected and were applied in a total of 339 pearl oysters. Observed heterozygosity and expected heterozygosity of the five microsatellite loci ranged from 0.360 to 0.681 and 0.429 to 0.672, respectively. Four loci (2PM206, 4PM34, 4PM50, and PM6) deviated from Hardy–Weinberg equilibrium (P > 0.05). Four growth traits, including shell height (SH), shell length (SL), shell width, and total weight (TW) were measured in all 339 samples. After Bonferroni correction, markers 2PM206, 4PM34, and 4PM50 were correlated with all four growth traits. Marker PM6 was significantly correlated with SH, SL, and TW, and marker 3PM10 was associated with SH and SL traits (P < 0.05). These results provide useful information for marker‐assisted breeding programs in P. fucata martensii.
