Seven populations and five mutant lines of the Andean lupin and four species from the section Albus were screened for their mitochondrial and chloroplast polymorphisms. For this purpose the RFLP method with EcoRI as a restriction enzyme was used. Lupinus luteus, Lupinus albus and Phaseolus vulgaris organellar clones as well as amplified fragments were used as probes. We found that mitochondrial probes were more suitable than chloroplast probes for identification of inter- and intra-specific variations within the examined material. Most mitochondrial probes differentiate the two species investigated. A high level of mitochondrial polymorphism was observed among the populations of L. mutabilis in contrast to monomorphism among the species in the section Albus. A limited polymorphism was detected between the mutant lines of L. mutabilis. We conclude from this study that the mitochondrial RFLP analysis is a valuable tool for identification of variability among Andean lupin populations.

coconut water. Somatic embryos were formed on the surface of cotyledons of immature embryos. The process of was observed only on cotyledons of whole explants. Unfortunately, cotyledons isolated from the embryo axis did not produce somatic embryos. In the subepidermal cell layer, the initial cell divisions leading to somatic embryo formation were observed. The number of regenerated somatic embryos varied from one to many per cotyledon. Somatic embryo derived plantlets formed very good root system in perlite supplemented with medium. Cytological and anatomical evidences of this process are presented in this paper.

The cultivated American species Lupinus mutabilis was selected in order to assess its possibilities of being introduced as an alternative high protein crop in Polish conditions. The realized programme involved identification of earlier maturing and higher yielding genotypes as well as interspecific hybridization with lupins belonging to section Albus, which includes the oldest cultivated species Lupinus albus. Recent reports (1) on determination of DNA polymorphism by the PCR method indicate usefulness of direct application of small amounts of pollen. The advantage of this method is the precisely determined and physiologically stable material used for the analysis. Furthermore, pollen can be preserved above the hygroscopic substance at ?20oC for a long time and small amounts of pollen (20-100 grains) can be used for the analysis without any damage to the plant material. For PCR reaction, ten selected primers were used. A polyacrylamide gel comparison of the PCR products revealed that random primers as well as primers which amplified a fragment of the whole gene can be applied to analyse the DNA of polymorphism of L. mutabilis and L. albus. The conclusion is that it is possible to differentiate within both groups of species by application of pollen to DNA analysis.

The limited gene pool used in breeding decreases the level of genetic diversity in legume cultivars. Morphological or physiological characters are not always sufficient for quick, easy and precise cultivar description. Isozyme variability of 33 commercial Polish pea cultivars was analysed. The level of allozyme polymorphism discovered was high enough for the identification of all cultivars within two groups: white flowering peas for human consumption and colored flowering peas for fodder. The range of RAPD marker polymorphism among three lupin crops (white lupin, narrow-leafed lupin and yellow lupin) was tested. It was possible to identify each of four white lupin cultivars by means of bands generated by two primers. Seven narrow-leafed lupin cultivars were distinguished using three other primers. Testing of RAPD marker polymorphism, supplemented in some cases with observations of seed coat color genes, allowed to identify all 12 yellow lupin cultivars. Thirteen field bean cultivars were tested by isozyme variability and RAPD polymorphism observations. Among 15 enzyme systems investigated, 10 showed a high level of inter- and intracultivar polymorphism but the range of allozyme variability discovered was useless for cultivar identification. All cultivars analysed could be distinguished by a combination of RAPD markers amplified using two primers.

The pollen grain germination and the growth of pollen tubes after intra and interspecific reciprocal polination of Lupinus albus L., Lupinus mutabilis Sweet. and Lupinus angustifolius L. were examined.Results of microscopic observations of pollen grain germination and pollen tube growth enable to deny the existence of certain barriers that prevent fertilization after pollination of L.albus flowers with pollen of L.angustifolius and vice versa, as well as after pollination of L.mutabilis flowers with pollen of L.angustifolius and vice versa.Some delay in pollen grain germination and a slower growth of pollen tubes were observed in all combinations, as related to intraspecific ones, though in case of each intrspecific combination pollen tubes reached the ovary.Moreover, a different level of pollination grain germination and pollen tube growth, depending on the direction of pollination, were found.The noted pollination efficiency may generally considered to be low.
