Abstract
Investigation was conducted for critical
assessment of stability in Lucerne (Medicago sativa). Ten
genotypes including one check variety (RL-88) were
evaluated at AICRP . on forage crops, MPKV, Rahuri,
Maharashtra in three seasons. Five cuts were taken in
summer 2008 and six cuts were taken in Kharifand Rabi-
2008 season each.Data were recorded on the traits viz., plant
height, internode length, number of tillers, leaf length, leaf
breadth, green forage yield, dry forage yield, crude protein
(%), crude fiber (%), crude protein yield, ADF (%) and NDF
(%).
Significant G x E interaction was observed for
plant height, internode length, green forage yield, dry
forage yield, crude protein(%) and ADF (%).
The linear component of G x E interaction was
highly significant for plant height (em), GFY and DFY when
tested against pooled error, where as it was high significant
for the traits crude protein (%) and ADF (%) when tested
against pooled deviation.
The non linear components of G x E interaction
(pooled deviation) ·was found to be highly significant for
plant height (em), green forage yield (qjha) and dry forage
yield (q/ha).
In present investigation the genotypes RLH-4
(plant height, and dry forage yield), RL-88 [plant height and
crude protein (%)], RLP-06-03 (green forage yield and dry
forage yield). The genotypes RLP-06-03, 01, 05, RL - 88
(internode length) and RLH-2 [dry forage yield and ADF
(%)1 were found to be promising and had
