Genetic linkage map of Cucurbita maxima with molecular and morphological markers

Y. Ge, Li, X., Yang, X. X., and Qu, C. S. Cui and S., Genetic linkage map of Cucurbita maxima with molecular and morphological markers, vol. 14. pp. 5480-5484, 2015.

Cucurbita maxima is one of the most widely cultivated vegetables in China and exhibits distinct morphological characteristics. In this study, genetic linkage analysis with 57 simple-sequence repeats, 21 amplified fragment length polymorphisms, 3 random-amplified polymorphic DNA, and one morphological marker revealed 20 genetic linkage groups of C. maxima covering a genetic distance of 991.5 cM with an average of 12.1 cM between adjacent markers.

High segregation distortion in maize B73 x teosinte crosses

G. Wang, He, Q. Q., Xu, Z. K., and Song, R. T., High segregation distortion in maize B73 x teosinte crosses, vol. 11, pp. 693-706, 2012.

Two genetic linkage maps of cultivated maize inbred lines and teosinte species were constructed. One population comprised 81 F2 individuals derived from a cross between maize inbred line B73 and Zea mays ssp parviglumis, while the second consisted of 63 backcross individuals from a cross of maize inbred line B73 with Z. mays ssp diploperennis. In the B73 x Z. mays ssp parviglumis F2 population, 172 simple sequence repeat (SSR) markers were mapped to 10 chromosomes, which covered 2210.8 cM.

Genetic linkage map of EST-SSR and SRAP markers in the endangered Chinese endemic herb Dendrobium (Orchidaceae)

J. J. Lu, Wang, S., Zhao, H. Y., Liu, J. J., and Wang, H. Z., Genetic linkage map of EST-SSR and SRAP markers in the endangered Chinese endemic herb Dendrobium (Orchidaceae), vol. 11, pp. 4654-4667, 2012.

Dendrobium officinale is an endangered orchid from southeast Asia that is known for its medicinal properties in traditional Chinese medicine. We constructed an integrated genetic linkage map of an F1 population derived from an interspecific cross between D. officinale and D. aduncum (both, 2n = 38), using expressed sequence tag-simple sequence repeats (EST-SSR) and sequence-related amplified polymorphism (SRAP). A total of 349 polymorphic loci, including 261 SRAP loci and 88 EST-SSR loci, were identified for genetic linkage analysis.
