Abstract

<p>This is the first report on the production of double-haploid chickpea embryos and regenerated plants through anther culture using Canadian cultivar CDC Xena (kabuli) and Australian cultivar Sonali (desi). Maximum anther induction rates were 69% for Sonali and 63% for CDC Xena. Under optimal conditions, embryo formation occurred within 15-20 days of culture initiation with 2.3 embryos produced per anther for CDC Xena and 2.0 embryos per anther for Sonali. For anther induction, the following stress treatments were used: (1) flower clusters were treated at 4 degrees C for 4 days, (2) anthers were subjected to electric shock treatment of three exponentially decaying pulses of 50-400 V with 25 microF capacitance and 25 Omega resistance, (3) anthers were centrifuged at 168-1,509g for 2-15 min, and finally (4) anthers were cultured for 4 days in high-osmotic pressure (563 mmol) liquid medium. Anthers were then transferred to a solid embryo development medium and, 15-20 days later, embryo development was observed concomitant with a small amount of callus growth of 0.1-3 mm. Anther-derived embryos were regenerated on plant regeneration medium. Electroporation treatment of anthers enhanced root formation, which is often a major hurdle in legume regeneration protocols. Cytological studies using DAPI staining showed a wide range of ploidy levels from haploid to tetraploid in 10-30-day-old calli. Flow cytometric analysis of calli, embryos and regenerated plants showed haploid profiles and/or spontaneous doubling of the chromosomes during early regeneration stages.</p>

There are three main kinds of chickpeas: Desi, which has small, darker seeds and a rough coat; Bombay, which has slightly larger dark seeds; and Kabuli, which has lighter coloured seeds with a smooth coat. Chickpeas are an excellent source of the essential nutrients, iron, folate, phosphorus, protein and dietary fiber. Chickpeas are low in fat and most of this is polyunsaturated. Desi chickpeas have a markedly higher fiber content than Kabulis and hence a very low glycemic index which may make them suitable for people with blood sugar problems. The plant grows to between 20–50 cm high and has small feathery leaves on either side of the stem. Chickpea pods are short in length containing 2-3 seeds. ... [more]

Tissue Culture

Tissue culture is the growth of tissues or cells separate from the organism. This is typically facilitated via use of a liquid, semi-solid, or solid growth medium, such as broth or agar. Specifically, plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues or organs ... [more]
