The aim of the research work was to isolate biopolymer and to evaluate its emulsifying ability by formulating o/w type of emulsion. The biopolymer was isolated from the fruit pulp of Prunus insititia by treating with water. The aqueous extract was treated with an optimized ratio of dimethyl ketone and kept in refrigeration for 6 hours. The biopolymer was collected by centrifugation, dried and s...

The usefulness of random amplified microsatellite polymorphism markers to study the genetic diversity and relationships among cultivars belonging to Prunus salicina and P. domestica and their wild relatives (P. insititia and P. spinosa) was investigated. A total of 226 of 234 bands were polymorphic (96.58%). The 226 random amplified microsatellite polymorphism markers were screened using 15 ran...

Two trials involving 20 Prunus rootstocks were conducted under greenhouse conditions to screen for resistance to root-knot nematode [Meloidogyne javanica (Treub.) Chitwood]. Many of the tested materials are interspecific hybrid rootstocks and represent new commercial peach (P. persica Batsch) and plum (Prunus sp.) releases or experimental genotypes of Spanish, French, and Italian origin. In the...

Crown gall is an important disease of many fruit and nut crops, but little is known about sources of resistance. We screened germplasm from Prunus armeniaca L., P. angustifolia Marsh., P. argentia L., P. avium L., P. besseyi Bailey, P. bokhariensis Schneid., P. brigantica L., P. cerasifera Ehrh., P. cerasus L., P. dulcis (Mill.) D.A. Webb, P. fruiticosa Pall., P. hortulana Bailey, P. insititia ...

The Maddenia clade of Prunus L. is monographed based on herbarium and field studies. Four species are currently accepted in this group: Prunus himalayana J.Wen, Prunus hypoleuca (Koehne) J.Wen, Prunus hypoxantha (Koehne) J.Wen, and Prunus gongshanensis J.Wen, with the last described herein as a new species. Maddenia fujianensis Y.T.Chang and Maddenia incisoserrata T.T.Yü & T.C.Ku are treated as...
