Registration of ‘Krib’ new lentil variety in Tunisia

In Tunisia, lentil (Lens culinaris subsp.
culinaris Medik.) is cultivated in arid and semi-arid
areas. Terminal drought and heat stresses during the
end of cycle causes signifcant yield losses. Selection of short cycle varieties could be the best option
to escape the efect of pre cited abiotic factors. ‘krib’
was developed using both modifed pedigree and bulk
methods by INRAT in collaboration with ICARDA.
It’s a selection from an advanced F9 line, FLIP2012
196L, which was derived from a cross of ILL590
(early-maturing genotype) with ILL8113 (drought
tolerant). During the three consecutive cropping
seasons (2014–2017), the increase in yield of ‘krib’
above that of the local checks was about 13 and 15%
for ‘kef’ and ‘Boulifa’, respectively. ‘Krib’ is an earlyfowering (on average~93 d) and early-maturing (on
average~138 d) variety. It’s therefore, the earliest
variety among the previously released varieties. Its
dehulled seed has a protein content of 26.8% which
was above that of ‘Kef’ (23.9%). ‘Krib’ showed good
agronomic performance under drought conditions
and large adaptation for the Tunisian environments.
Tested as ILL11171, ‘Krib’ was approved for release and registered in the Tunisian Ofcial Catalogue of Plant Varieties in 2019, based on the superior performance, by the DG/PCQPA, Tunisia. The availability of ‘Krib’ variety to farmers could increase lentil production and ofers the producer aproftable beneft in
their cropping systems.
