Primary Focus

Efforts to improve the yield and quality of cultivated chickpea (Cicer arietinum L.) are constrained by a low level of intraspecific genetic diversity. Increased genetic diversity can be achieved via the hybridisation of the cultivated species with the unimproved 'wild' relatives from within the 43 species of the Cicer genus. To date, the 8 species sharing an annual growth habit and chromosome number with C. arietinum have been the primary focus of screening and introgression efforts. Screening of these species has uncovered morphological characteristics and resistance to a number of abiotic and biotic stresses that are of potential value to chickpea improvement programs. Detailed analysis of protein and DNA, karyotyping, and crossability studies have begun to elucidate the relationships between the annual Cicer species. In comparison, perennial species have received little attention due to difficulties in collection, propagation, and evaluation. This review discusses the progress towards an understanding of genetic relationships between the Cicer species, and the introgression of genes from the wild Cicer species into the cultivated species.

Chickpea Cultivars

Phytophthora root rot caused by Phytophthora medicaginis is a major disease of chickpea in Australia. Only partial resistance, derived from chickpea, is available in Australian cultivars. Five wild Cicer species were compared with chickpea cv. Jimbour (moderately resistant) in a field experiment. The proportions of accessions with significantly lower (P < 0.05) disease scores, where lower scores equate to higher resistance, were 9/9 for C. echinospermum, 9/21 for C. bijugum, 1/4 for C. judaicum, 1/29 for C. reticulatum, and 0/3 for C. pinnatifidum. The resistance of C. echinospermum (7/7 accessions) but not the other Cicer species was reproduced in a greenhouse test. Nine out of 30 chickpea × C. echinospermum-derived lines were as resistant as the C. echinospermum parents in a separate greenhouse experiment. C. echinospermum appears to be the best of the sources we examined for breeding chickpea cultivars resistant to P. medicaginis.

Ald Gene

Fructose-bisphosphate aldolase (ALD, EC 4.1.2.13) was analysed in Cicer arietinum L. (the cultivated chickpea) and all eight annual wild Cicer species, C. bijugum Rech., C. chorassanicum (Bge.) M. Pop., C. cuneatum Rich., C. echinospermum Davis, C. judaicum Boiss., C. pinnatifidum J. &S., C. reticulatum Lad., and C. yamashitae Kit. Duplicate genes were identified for the plastid-specific isozyme of ALD in C. arietinum and all wild species except C. yamashitae and one accession of C. reticulatum. Gene duplication was indicated by the presence of a true-breeding five-banded zymotype of the tetrameric plastid ALD in these species. Monogenic inheritance was confirmed for the alleles of one of the loci. The occurrence of ALD gene duplication in most of the annual Cicer species suggests that this duplication is of ancient origin. However, this duplication must have occurred after divergence of Cicer from the closely related genera Pisum and Lens because the plastid ALD is controlled monogenically in these latter two genera.Key words: Cicer, isozymes, aldolase, gene duplication.

Winter Annuals

Chickpea (Cicer arietinum) developed as a post-rainy season, spring-sown crop early in its evolution and spread into warm subtropical regions, in contrast to its wild relatives that have remained as winter annuals in West and Central Asia. To test whether these different life cycles selected for different phenological strategies in wild and cultivated Cicer, germplasm from a wide range of habitats was subjected to different cold treatments (vernalisation, control) at germination, and phenology evaluated at warm and cool field sites (14.8–15.1°C and 13.1°C, respectively). All wild Cicer species, except for C. yamashitae, responded positively to vernalisation and accelerated the dates of flowering, podding, and maturity. There was no vernalisation response in cultivated chickpea, whereas C. arietinum/C. echinospermum and C. arietinum/C. reticulatum interspecific hybrids were intermediate, flowering 6–16 days earlier after vernalisation. Relative podding dates differed between sites. Chickpea podded earlier than most vernalised wild species under warm conditions, but not at the cool site. Regression against post-anthesis temperature showed that the delay in podding was consistent with a lack of cold tolerance in the cultigen. The interspecific hybrids were significantly more cold tolerant than chickpea, and the wild species were almost insensitive to the temperature range recorded at the cool site. Vernalisation responsiveness and a greater tolerance of low temperatures during the reproductive phase demonstrate that the annual wild Cicer species harbour important traits that can be used to widen adaptation in the cultigen, and may help to improve the performance of chickpea as a Mediterranean cool-season crop.
