Developing medium to large seeded kabuli

chickpeas with early maturity, improved yield and

Ascochyta bight resistance for Australian

growers

G. Borgognone and L McMurray

Australian Pulse Conference – Kristy Hobson – DPI Agriculture – 13th September 2016

Kabuli chickpea production Prior to 2005, Australia’s main kabuli varieties were a seed

size of 8 mm or greater

Kaniva, Bumper, Garnet

These varieties required favourable spring conditions to

achieve good yields and seed size

Ascochyta blight resistance was essential for low risk and

profitable production in south eastern Australia

The release of Genesis™090 in 2005 started a small

seeded (7-8 mm) kabuli market class

Genesis™079 (6-7 mm), Genesis™425 (7-8 mm)

High yields, wide adaptation, good Ascochyta blight

resistance and prices at least equivalent to desi

Kabuli chickpea adaptation

Genesis™090 set a new bench mark for kabuli yield and

adaptation - “Debuli”

Medium and large seeded kabuli varieties had a 15% yield

gap

Improving medium to large seeded

kabuli adaptation Earlier flowering medium to large kabulis would commence

pod fill earlier (if temperatures were conducive) and produce

larger seed size in shorter seasons

Improved farming system ‘fit’ – weed control options

PBA Monarch released in 2013

Early flowering medium seed size, MS rating for AB

Selected and evaluated in a period of tough short

seasons (2000’s)

Moving target

Harvestability

Current trends in kabuli production

The future

The development of earlier flowering and maturing

germplasm has improved the adaptation of medium to large

seeded kabulis

Ascochyta blight resistance will continue to be a major

objective

Chickpea production continues to grow in the northern

region and shrink in the southern region

Improving Phytophthora root rot (PRR) resistance is

essential to support further expansion of kabuli production

in the northern region
