BA29 is a Provence quince selection of INRA's Anger station whose name reflects the Bois Abbe trial orchard of origin at Beaucouze, near Angers. Released in the late 1960s, it is best suited to plantations in southern Europe and became very popular during the 1980s and 1990s because it is easy to propagate, and is the quince stock most tolerant to high lime soil and only moderately susceptible to chlorosis. Nevertheless, it is not the ideal stock for use in soils of heavy clay or poor fertility. Most cultivars grafted to BA29 in France, but not always in Italy, have proved to be 10-15% more vigorous and higher yielding than when grafted to Sydo or Malling A. The major drawback of BA29, aside from its higher vigor in fertile soils, is its low tolerance to infectious viruses and pear decline. It is only moderately susceptible to fire blight. -- Dondini and Sansavini, 2012. Provence Quince (BA 29-C) is a selection from the species Cydonia obonga, which was produced by the Institute National de la Recherette Agronomique (INRA) in France. Reports from France indicate that BA 29-C is a virus-free selection of Provence Quince, Le Page Series C. Provence Quince BA 29-C is precocious, very high yielding and produces trees anywhere from 1/2 to 2/3 the size of standard pear trees. Provence Quince BA 29-C is incompatible with some pear varieties, resulting in the use of an interstem or stem piece between the scion variety and the understock. The stem pieces most commonly used are Old Home and Hardy. Provence Quince BA 29-C is more compatible with some Bartlett selections. Resistant to pear decline, crown gall, nematodes and root aphids, and more resistant to calcareous soil types than other quince rootstocks. -- TRECO Nursery Catalog, 2012
