“…In earlier studies with a limited number of accessions, L. ochrus was identified as a source of resistance to Orobanche crenata by Sillero et al (2005). In the past, only few attempts were made for interspecific hybridization among Lathyrus species (Davies, 1958;Hammett, Murray, Markham, Hallett, & Osterloh, 1996;Kearney, 1996;Khawaja, 1985Khawaja, , 1988Trankovskij, 1962;Yamamoto, Fujiware, & Blumenreich, 1986;Yunus, 1990;Yunus & Jackson, 1991).

Broomrape weeds (Orobanche spp.) are root holoparasitic plants that cause serious damage to a range of legume crops in the Mediterranean and sub-Saharan African regions. Grain yield of cultivated species of grass pea (Lathyrus sativus L.) is almost negligible at the highest infection severity of Orobanche. Crop wild relatives (CWRs) have emerged as a novel source for many traits in diverse crops. Lathyrus is one of the largest genera with more than 160 species. In the present study, we screened 285 accessions representing 13 Lathyrus species for their reactions against two common broomrape species, Orobanche crenata Forsk. and O. foetida Poir, under field conditions. Screening at hot spots in Morocco and Tunisia resulted in the identification of resistant accessions of wild Lathyrus species against the parasitic weed. The level of resistance to O. foetida was higher among wild species compared with O. crenata. Field results showed complete resistance for O. crenata and O. foetida by L. articulatus L. and moderate resistance by L. aphaca L. and L. ochrus (L.) DC. Resistance to O. crenata in L. sativus accessions was validated in a pot experiment under controlled conditions. Two accessions-namely, IG64782 and IG65197-showed complete resistance to O. crenata. A moderately resistant accession, IG116989, that revealed low infestation in the field showed high susceptibility in pot experiment. The results indicated that the resistance against O. crenata and O. foetida was associated with slow development of the established tubercles and low induction of parasite germination.

Seed Number, Seed Size and Seed Diversity in Washington Lupin (Lupinus polyphyllus Lindl.)

2001

View full text Add to dashboard Cite

Over 20 000 seeds of the Washington lupin (Lupinus polyphyllus Lindl.) were examined and measured in an experiment carried out over a 10 year period (1989±1999). Four dierent groups of Washington lupin seeds were found: dark, patterned, grey and light seeds. During the 10 year experiment, the total average number of seeds per plant decreased from 2654 (1990) to 1220 (1999), there was a slight decrease in seed weight per plant and an increase in the average weight per seed. There was a clear seed size/number trade-o at the intraspeci®c level. The relative proportions of each seed group also changed with patterned seeds becoming dominant (50 % at the beginning and 90 % at the end of the experiment), grey seeds remained constant (constituting 10 % of the total seeds) and the proportion of both dark (33 % at the beginning and 5 % at the end) and light (10 % at the beginning and 5 % at the end of the experiment) seeds decreased. Six hundred and sixty nine seeds were found to have a dierent testa ornamentation; they were distributed among the dierent groups as follows: 48 % patterned seeds, 29 % dark seeds, 12 % grey seeds and 11 % light seeds. There were no signi®cant dierences in the physical dimensions of the ornamented seeds compared with all other seeds. The results suggest that the Washington lupin is a mixture of dierent species and botanical forms; this is discussed in relation to possible selection pressures to produce both smaller and larger seeds. The possibility that changes in testa ornamentation are in¯uenced by genes controlling the synthesis of the seed coat pigment is discussed.

Isozyme patterns for aspartate amino transferase, alcohol dehydrogenase and superoxide dismutase were evaluated in 60 accessions of eleven Vicia taxa occurring in Algeria. The three enzymatic systems revealed 25 morphs of different frequency encoded by 7 loci. Similarity between species and accessions was estimated by Euclidean distances based on presence or absence of bands. The UPGMA method was utilized for the groupings and dendrogram construction. The dendrogram presented 2 major groups, each one corresponding to a taxonomic level where accessions of the same species grouped together. Taxa-specific bands were identified. In parallel, 12 physical seed properties namely: length, width, thickness, arithmetic diameter, geometric diameter, sphericity, surface area, volume, square mean diameter, equivalent diameter, seed aspect ratio and 1000 seed weight were calculated. By cluster analyses based upon them, the material has been classified into 2 major groups with no correspondence with the current taxonomy. A Principal Component Analysis was undertaken to distinguish physical properties which contribute the most to accessions distinction. Mantel test was used to assess correlation between the three enzymatic systems studied one side and between enzymes polymorphism and physical seed properties another side.
