Advances in groundnut (Arachis hypogaea L.) breeding for resilient cropping systems in Burkina Faso
Introduction
Improved groundnut varieties have been introduced from ICRISAT Mali in 2013 and evaluated during three (3) years on the experimental station of Gampela in Burkina Faso. Objective : Compare the pods and haulm yields of two (2) varieties tolerant to foliar diseases, three (3) varieties tolerant to aflatoxins et two (2) varieties (one improved and
one local) tolerant to drought to two (2) varieties released in Burkina Faso.
Results Yields of two varieties tolerant to foliar diseases compared to two varieties released in Burkina Faso

Yields of varieties tolerant to drought compared to two varieties released in Burkina Faso
Discussion During the three years, there were statistical differences between varieties for both the pods and the haulm yields. The yields of introduced varieties are superior to those of released varieties excepted for the drought tolerant varieties where QH 243C has the best haulm yield. ICGV 86015 has both interesting pods and haulm yield (1694.2 kg.ha-1
and 3641 kg.ha-1) followed by ICGV 93305 (1344.5 kg.ha-1 and 3345 kg.ha-1). These interesting results obtained are similar to those observed at the small stakeholders’ level who follow recommended practices including optimal crop density and planting time and then they benefit from the yields improvements.

These varieties have been analyzed by the method ELISA Test of ROMERLABS. We used the
Kit AgraQuant 1-20 ppb and the Reader “STAT FAX 303” for quantification of aflatoxins.
ICGV 91328, ICGV 91283, ICGV03323, ICGV 93305, ICGV 03315 and ICGV 91317 have the
lowest contents of aflatoxins. These analysis permitted us to choose and use some varieties in our trials like tolerant varieties to aflatoxins

Fig.1: Pods yield
During the three (3)
years, there is a
significant difference
between the varieties
(p<0.001). ICGV 86015
has the best mean pods
yield (1694.2 kg.ha-1
)
followed by ICGV
01276 (1571.6 kg.ha-1
).
QH 243 C (1267.5
kg.ha-1
) has a pods yield
higher than SH 470 P (1049.9 kg.ha
-1)
Fig. 2: Haulm yield
Concerning haulm
yield, there is also a
significant difference
(p<0.01) between the
varieties. ICGV 86015
has again the best
haulm yield (3 641
kg.ha-1
) followed by
ICGV01279 (2659.7
kg.ha-1
) and QH 243C
(2526.5 kg.ha-1
). SH
470 P has the lowest yield (2085.8 kg.ha

Fig.4: Pods yield
We observe a statistical
difference between the

pods yield (respectively
1372.8 kg.ha-1

)
and QH 243C (1267.5
kg.ha-1

the lowest pods yield
(1049.9 kg.ha-1
).
Fig.5: Haulm yield The haulm yield of the varieties differ statistically from one variety to another one (p<0.01). ICGV 93305 has the highest haulm yield (3345.3 kg.ha
-1) followed by
ICGV 91317 (2533.3 kg.ha
-1) and QH 243C

Fig.6: Pods yield
The pods yields of
the varieties differ
statistically (p=0.19),

(1399.7 kg.ha-1
) and
QH 243C (1267.5
kg.ha-1
) have the best
pods yield followed
by Kiema (1156.8
kg.ha-1
).
Fig.7: Haulm yield
QH 243C and
Kiema have the
highest haulm yield
(respectively 2526.5
kg.ha-1
and 2270.8
kg.ha-1
). ICIAR 19
BT and SH 470P
have the lowest
yield (2019.6 kg.ha-1
and 2085.8 kg.ha-1
).
(p=0.28).
