Wild taxa of crop plants have been valuable sources of genes for cultivar improvement in several species. Genes for yield, resistance to pests and diseases, protein quality and quantity, maturity and other characteristics have been transferred from wild species of Avena to the cultivated oat crop (A. sativa L.). In an attempt to preserve some of the genetic variability in the wild species and taxa of Avena, two collecting missions were organised in 1985 and 1988. During the 1985 expedition 49 accessions were collected on mainland Spain and the Canary Islands, and 74 accessions were collected in Morocco. In 1988, a further 64 accessions were collected in Morocco. These accessions included representatives from 10 of the 14 known biological species of Avena and 16 of the 30 generally accepted taxonomic entities. These collections have increased the size of the available gene pool and extended the known geographical distribution of some of the species. Key words: Avena, distribution, germ plasm, genetic resources.

Assessment of genetic diversity in the available germplasm is the prerequisite for development of improved genotypes through planned breeding programmes. In the view of this Forty-eight genotypes of seedling origin guava along with 1 check (L-49/Sardar) collected and conserved at germplasm block, Main Garden, Department of Horticulture, Dr. P. D. A. University, Akola were evaluated for genetic variability and diversity based on the qualitative characteristics. The genotypes were evaluated for sixteen morphological traitsviz. tree, leaf, floral and fruit traits. Results Show considerable extent of variability amongst the 49 genotypes in each traits. A sizeable amount of intrapopulation diversity recorded can be used to identify diverse parents which can be utilized in hybridization programmes.
