MEAN PERFORMANCE AND PHENOTYPIC STABILITY OF SOME FABA 3EAN (Wcia faba, L. VAR.MAJOR) GENOTYPES UNDER FOUR DIFFERENT LOCATIONS IN EGYPT.

Ten faba bean genotypes var. major were evaluated over eight different
environmental conditions ¡.e.Ismailia Alexandria, Qalubia and Sohag locations in a
combination with two seasons of 2001/2002 and 200212003 to investigate mean
performance and phenotypic stability for some green and dry yield characters and its
components. The eight field trials were conducted using randomized complete block
design with four replicaLions.The obtained data were subjected to analysis of variance
and the stability methods out line by Eberhart and Russel (1966).
Mean performance of some genotypes through various environments
revealed high potential response for favorable environments conditions. Moreover,
other genotypes showed high potential response under unfavorable environments.
Line (Ki) appeared to be performed well under favorable environment conditions for
pods weight! plant and number of both seeds/pod and pods/plant and Giza Planka for
pod length and 100-seeds weigh. On the other hand, line (Ks) was performed well
under unfavorable environmental condition for pod length and pods weight /plant. The
most highly stable genotypes for yield and its attributed characters were line (K1), line
(K7), line (K8) and Giza Planka cv. These results are of great importance to breed high
yielding and more stability faba bean varieties under varied environments.
