A core set of crop genetic resources are considered “first-look-sources” of trait-specific accessions for use in crop-breeding programs. Sixty-four core germplasm accessions of dolichos bean (Lablab purpureus L. Sweet Var. Lignosus) and two check entries were characterized/evaluated for five qualitative traits and seven quantitative traits at the University of Agricultural Sciences (UAS), Bengaluru, India, during the rainy seasons of 2012 and 2014. Substantial variability among the accessions for quantitative traits and polymorphism for qualitative traits were documented. The germplasm accessions could be grouped into six clusters following model-based K-means clustering approach. The quantitative trait means and variances of accessions distributed among the clusters differed significantly. The accessions superior for six productivity traits were identified. The accessions, such as GL 142, GL 527, GL 110, GL 447, GL 576, KA, FPB-35, GL 441, GL 12, and GL 66, were promising for multiple quantitativ...

PurposeLegume seeds provide one of the most concentrated sources of nutrients rich in fibre and high‐quality protein in the diet. The present work aims to investigate the hypocholesterolemic effect of germinated Indian bean (Dolichos lablab L. var lignosus) by feeding albino rats with a hypercholesterolemic diet.Design/methodology/approachMale albino rats of Wistar strain were divided into five groups (each group consisting of ten rats) according to randomized block design, housed in individual cages and fed with one of the five diets over an eight‐week period. At the end of eight weeks, the body weights were recorded and the rats put down. Samples of blood and liver were collected and used for analysis of liver and plasma cholesterol.FindingsSupplementation of the diet with dried powder of soaked bean almost brought the plasma cholesterol to 72.5 ± 0.75 from 178 ± 1.85 compared with that of the control (61.5 ± 0.70), although the liver cholesterol was still three times higher compared with the control. The 24h germinated Indian bean cotyledons could effectively counteract the effects of added cholesterol on liver and plasma by their high fibre content coupled with enormous increase in ascorbic acid levels.Originality/valueResults suggest germination to be a simple biochemical tool to effectively lower the cholesterol levels in liver and plasma by virtue of its higher contents of ascorbic acid and dietary fibre in ischemic heart disease patients.

A study was conducted to determine the spatial distribution of somatic incompatibility groups (SIGs) in Rigidoporus lignosus populations responsible for white root disease in a south Sumatera rubber plantation. Most isolates colonizing the stumps were somatically compatible with isolates from either a nearby stump or a living rubber tree, which suggested evidence of stump-to-tree or stump-to-stump clonal growth of the fungus. SIGs of R. lignosus occupied an area territorially in which the minimum size estimate for the largest genotype was 25 m in length.

The acitivty and spatial distribution of eight enzymes in adult tap root tissues colonized by R. lignosus and P. noxius are investigated. Their physiological significance in the pathogenic process is discussed.

A taxonomic revision of the genus Dipogon Liebm. is presented. Only one variable species, D. lignosus (L.) Verde., is recognized.

The effect ofFomes lignosus (Klotzsch) Bress onTriplochiton scleroxylon K. Schum was determined by artificially inoculating 5 to 6-week old seedlings, as well as by conducting a field survey on 1 to 4-year old trees. Inoculated seedlings did not show any foliar symptoms of infection during 4 months of observation. Though heights of inoculated seedlings were not affected by the pathogen, diameters of such seedlings were significantly smaller (atP=0.05) than those of control seedlings. Naturally infectedT. scleroxylon trees in the field were very often found close together, usually around infected tree stumps. Leaves of diseased trees remained healthy-looking, thus making detection of the disease difficult in trees lacking signs (viz. rhizomorphs and fruitbodies) of the pathogen.

Electron microscopic studies of roots of young Hevea brasiliensis plants artificially infected with Rigidoporus lignosus and Phellinus noxius are described. Rigidaporus lignosus differentiates specialized structures which penetrate the suberized tissue. For both fungi, cell colonization is characterized by the degradation of suberized walls. The observations indicate that cell wall alteration is predominandy due to enzymatic activity. The significance of these observations in relation to the pathogenicity of both parasites is discussed.

As part of our studies on the chemical, functional, and nutritional roIe of food carbohydrates, various starchy and nonstarchy polysaccharides of the field-bean (Doiic/zos /ablab, variety lignosus) endosperm and hulls have been isolated and characterized’. Some structural features of the cold-water-soluble polysaccharides are described in this communication.

the buried leg of a wooden post. It has been reported also from the western tropics (Porto Rico) and from the temperate region of North America (Washington, Texas, Missouri) by Dr. Overholts. It is not found in Europe. Fomes lignosus and Polyporus microporus are now regarded as its synonyms. In the Trans. Brit. Myc. Soc. (1928) Mr. Petch has entered fully into the history and reconsideration of the synonyms. According to him the so-called " Fomes lignosus," which is really an unnamed species, is a parasite and never grows on fallen branches, while Polyporus zonalis is a

Forms lignosus (Klotzsch) Bres. and Polyporus zonalis Berk., both occurring parasitically and saprophytically, are described from sporophores and cultures. F. lignosus is orange-red on the upper surface with orange-yellow margin and orange-red pore tubes fading towards the context. In P. zonalis the surface is pale to pinkish with white pore tubes. The presence of mucronate cystidia in the sporophore and of fibre hyphae and conidia in cultures distinguishes F. lignosus from P. zonalis in which they are absent. The latter, however, develops incrusted cystidia in the sporophore and clamped hyphae and acanthophyses in culture, all absent from F. lignosus.

Polyporus lignosus is often confused with P. zonalis . They are two distinct species. Besides other characters, P. lignosus is usually parasitic while P. zonalis is commonly saprophytic. The two fungi are distinguished by their cultural characters. While rhizomorphic strands develop in P. lignosus as in nature, such strands are absent in P. zonalis , both in nature and in culture. Further, P. lignosus , with its thin-walled hyphae with cross-walls, can be distinguished from P. zonalis , in which the hyphae are very thick-walled and contain no visible cross-walls. No hyphal fusions occur when P. lignosus and P. zonalis are paired in culture.
