“…Tea has a genome size of 4 Gb ( Tanaka et al 2006 ); its basic chromosome number is n = 15 ( Morinaga et al 1929 ) and it is commonly diploid. Since tea is an outcrossing woody plant with a self-incompatible reproductive system ( Tomo et al 1956 ), its genome is always heterogeneous. Traditionally, tea trees have been propagated as seedlings, but seedling tea trees do not have synchronous bud break, uniform harvest times and uniform quality.…”

A few linkage maps of tea have been constructed using pseudo-testcross theory based on dominant marker systems. However, dominant markers are not suitable as landmark markers across a wide range of materials. Therefore, we developed co-dominant SSR markers from genomic DNA and ESTs and constructed a reference map using these co-dominant markers as landmarks. A population of 54 F1 clones derived from reciprocal crosses between ‘Sayamakaori’ and ‘Kana-Ck17’ was used for the linkage analysis. Maps of both parents were constructed from the F1 population that was taken for BC1 population. The order of most of the dominant markers in the parental maps was consistent. We constructed a core map by merging the linkage data for markers that detected polymorphisms in both parents. The core map contains 15 linkage groups, which corresponds to the basic chromosome number of tea. The total length of the core map is 1218 cM. Here, we present the reference map as a central core map sandwiched between the parental maps for each linkage group; the combined maps contain 441 SSRs, 7 CAPS, 2 STS and 674 RAPDs. This newly constructed linkage map can be used as a basic reference linkage map of tea.

Data are presented for the inorganic chemical constituents of tea leaf collected from four different clones grown in Assam. Samples were collected on three different dates during the period July to September, 1g56. Analyses were made separately of bud, 1st leaf, etc. The data presented show that chemical composition of tea leaf varies not only with physiological age and date of sampling but also with the clones.
