Name and synonyms:
Ambar is a hindi/urdu (the most widely spoken languages in the Indian Subcontinent) word meaning the gem - Amber. This follows the WA convention of naming chickpea varieties in the language of the target market and referring to gems or precious metals found in Australia. It has been tested as WACPE2136 and 99262-WA10.
Area of Adaptation:
Ambar is well adapted to most of the southern Australia with particular preference for the northern wheatbelt of Western Australia. Its early flowering habit makes it well suited to shorter growing season (low rainfall) environments.
Breeding: This variety was developed by Dr Tanveer Khan (former DAFWA Plant Breeder), Winthrop Professor Kadambot Siddique (The University of Western Australia) and the Pulse Breeding Team of DAFWA. Ambar was developed from germplasm bred by Mr Ted Knights from the NSW Department of Primary Industries, Tamworth as part of the GRDC National Chickpea Breeding Program. The cross 99262 (pedigree: ICCV92501/ICC13729//WACPE2021/ICCV96808) was developed by NSW DPI to a F3 population and subjected to natural selection for ascochyta blight resistance under high disease pressure at Tamworth that increased the frequency of resistance.
This population was distributed to DAFWA as part of the National Chickpea Breeding Program. The segregating population was grown at Merredin 2003 and subjected to a further ascochyta blight epidemic. A single plant showing ascochyta blight resistance and desirable agronomic traits was selected by Dr Khan and harvested individually. Progeny of the single plant was grown in 2004, again at Merredin, along with other single plant selections. This line was then observed as genetically fixed and tested at multi-location breeding trials until 2011.
- The agronomy of growing Ambar is similar to all current Australian chickpea varieties.
- Ambar has the following agronomic characteristics.
- Ambar is the earliest flowering and earliest maturing variety of the current varieties in southern Australia.
- Similar plant height to PBA SlasherA.
- Like PBA Slasher, Ambar is a shorter bushy semi spreading plant type.
- Lodging has not been seen in any trial in WA including trials where AmbarA has yielded more than 4 t/ha.
- Ambar has robust resistance to ascochyta blight as found over several years of testing in WA and in various environments in India and NSW.
