Genetic relationships analysis of olive cultivars grown in China

M. M. Zhan, Cheng, Z. Z., Su, G. C., Wang, A. Y., Chen, H. P., Yang, Z. S., Shan, Z., and Huang, Q. M., Genetic relationships analysis of olive cultivars grown in China, vol. 14, pp. 5958-5969, 2015.

The olive tree is an iconic tree of the Mediterranean, and is used extensively to produce high-quality olive oil. Although the China olive industry has just begun to be valued, there were also existed mislabeling and synonyms in introduced cultivars. The aim of this study was to analyze genetic similarities among olive cultivars in China using SSR and ISSR techniques. Thirty-two samples were collected from Xichang. Five of these cultivars were issued from a Chinese breeding program.

Identification of hybrids between triticale and Aegilops juvenalis (Thell.) Eig and determination of genetic similarity with ISSRs

A. Gradzielewska, Gruszecka, D., Leśniowska-Nowak, J., and Paczos-Grzęda, E., Identification of hybrids between triticale and Aegilops juvenalis (Thell.) Eig and determination of genetic similarity with ISSRs, vol. 11, pp. 2147-2155, 2012.

Wide hybridization expands the gene pool of cultivated species and can produce genotypes with practical value, often resistant to diseases. In plants, ISSRs are often used for hybrid identification as well as for diversity evaluation. We estimated genetic similarity among advanced genetic stocks of triticale hybrids and identified Aegilops juvenalis introgressions into triticale. Fourteen ISSR primers amplified from 12 to 23 DNA fragments. The number of polymorphic products per primer ranged from three to nine, with a mean of 5.1.

RAPD fingerprint construction and genetic similarity of Mesona chinensis (Lamiaceae) in China

G. F. Zhang, Guan, J. M., Lai, X. P., Lin, J., Liu, J. M., and Xu, H. H., RAPD fingerprint construction and genetic similarity of Mesona chinensis (Lamiaceae) in China, vol. 11, pp. 3649-3657, 2012.

Mesona chinensis is an economically important agricultural crop, primarily cultivated for making grass jelly. It was originally discovered in South China. We examined 18 cultivars, including cultivars from Guangdong, Fujian, and Guangxi, China, Taiwan, and Indonesia, and a hybrid (a cross between cultivars from Indonesia and Guangdong), based on RAPD markers. The genetic similarity coefficient was calculated by NTSYS 2.10 and the clustering analysis was made by UPGMA. PCR amplification with 10 primers produced 163 bands; 94% of the amplified loci were polymorphic.
