New pulse variety releases
GroundCover™ Issue: 137 November - December 2018
Five new pulse variety releases – three faba beans, a chickpea and a lentil – address previous disease resistance and yield limitations.
The faba beans are PBA Bendoc and PBA Marne (see previous story) and PBA Nanu. The desi chickpea is PBA Drummond. The red lentil is PBA Hallmark XT.
PBA Nanu has more uniform and larger seed than PBA Warda and slightly smaller than PBA Nasma, which makes it superior to PBA Warda for marketing while the smaller seed should improve handling at seeding.
PBA Nanu is well adapted to northern NSW where it has out-yielded PBA Nasma by two to four per cent in both low and high-yielding trial sites including the National Variety Trials. It has better resistance to rust than any other released varieties and its bean leaf roll virus (BLRV) resistance is the same as that of PBA Nasma.
Key features of PBA Nanu are:
- it is high yielding across all faba bean growing areas of northern NSW and southern Queensland;
- it has a similar level of resistance to BLRV as PBA Nasma;
- it has a similar flowering and maturity time to PBA Warda and PBA Nasma;
- it has larger and more uniform seed than PBA Warda, but slightly smaller than PBA Nasma; and
- it is suggested as an alternative to PBA Warda and PBA Nasma.
PBA Bendoc has similar yields to current faba bean varieties grown in southern Australia. It is resistant to pathotype 1 and pathotype 2 of ascochyta blight and tolerant to some imidazolinone (Group B) herbicides.
PBA Marne is the highest-yielding faba bean available for short-season areas in the southern region. It is early flowering, particularly when sown early, and is a medium-height plant with good standing ability.
PBA Drummond, the new desi chickpea for Central Queensland (including the Central Highlands and the Dawson and Callide valleys) is offering significantly higher grain yield than all current varieties in this region.
It has an improved level of ascochyta blight resistance over high-yielding, susceptible varieties such as PBA Pistol, Kyabra and Moti.
PBA Drummond is said to provide an excellent agronomic package with good harvestability. It is tall, erect and lodging resistant and has been in advanced yield evaluation since 2013 in a diverse range of seasonal conditions. PBA Drummond has acceptable seed quality similar to PBA HatTrick and equivalent dhal milling yield to current varieties.
Key features of PBA Drummond are:
- it is consistently high yielding across all areas of Central Queensland;
- its ascochyta blight resistance is better than PBA Pistol, Kyabra and Moti but not as good as PBA HatTrick; and
- it has mid-flowering and early-mid maturity.
However there is a limited supply of seed for some new varieties due to the dry seasonal conditions in 2018.
A new medium red lentil variety – PBA Hallmark XT – has also been released for the northern, southern and western cropping regions.
PBA Hallmark XT has improved tolerance of some Group B herbicides and is higher yielding than PBA Hurricane XT.
It has better early vigour and improved ratings for botrytis grey mould (BGM) than PBA Hurricane, and a similar ascochyta blight rating to this small red lentil variety.
Key features of PBA Hallmark XT are:
- it has a five to 12 per cent long-term yield advantage over PBA Hurricane XT;
- it is tolerant of applied imazethapyr at label rates and it;
- it is mid-flowering; and
- it has mid-maturity, which is slightly later than PBA Hurricane XT.
