“…Regarding days to opening first boll, no hybrids showed negative and significant mid parent heterosis. These results agreed with El-Feki et al, (2012) revealed that 1-general and 2-line specific and arrangement effects were significant indicating the importance of additive gene effects and all additive type of epistatic interaction. b.…”

Genotypes used in present investigation consisted of five cotton varieties belong to (Gossypium barbadense, L.). Three of these varieties were long staple, BBB (big black boll) (P1), Australian (P2) and G97 (P3) while the other two varieties were extra-long staple, Giza 92 (P4) and G96 (P6). Hybrids produced from these parents and evaluated with their parents in Sakha Agricultural Research Station, Egypt. Studied traits were; first fruiting node, days to first flower appearance, duration of the boll maturation, upper half mean (U.H.M), fiber strength and micronaire value. Highly significant differences among parents were detected for all traits, excluding days to opening first boll and upper half mean . Difference between single crosses was highly significant for all traits, except for days to first flower and upper half mean . Significant differences between double crosses were detected for all traits, excluding upper half mean . Alpha lattice analysis exhibited more efficiency than randomized complete block design at analyzing all of studied traits except for first fruiting node. Lowest values of (CV%) and SE were recorded for all traits excluding micronaire reading in Reml analysis which indicates high experimental precision

“…Also, 3-Line arrangement was highly significant (P≤ 0.01) for all traits except for days to opening first boll which was significant only (P≤ 0.05) indicating the contribution of the additive by dominance interaction including all three factors or higher order interaction except all dominance types. Similar trend of results were detected by El-Feki et al (2012) whom found highly significant 2-line arrangement and 3-Line arrangement for earliness traits and indicated that the order in which the parents were involved in double crosses was important.…”

“…were the best without respect to arrangement. El-Feki et al (2012) revealed that in all possible combinations without respect to arrangement (ijk) the best triple was (P 3 P 5 P 6 ) followed P 1 P 2 P 4 , P 1 P 2 P 5 and P 1 P 2 P 3 and P 2 P 4 P 5 .…”

“…While the two combinations p1 * p2 followed by p3 * p4 recorded negative and highest values in 2-line of (i-) (j-) type, on the other hand p1 * p3 was the worst compination. El-Feki et al (2012) studied double crosses hybrid and showed that the parents {Australian (P1), BBB (P2)},{Karshenky (P3) and Suvin (P5)} and {BBB (P2) and Giza 70 (P4)} had highest negative of 2-lines general effect. Three line arrangement Table 9 showed the three line arrangement in earliness traits.…”

“…These results a given confirm that the order in which the parents go into a double hybrids is deciding factor of high or low performance. El-Feki et al (2012) mentioned that parents (Australian, BBB,), (Australian, BBB, G70, suvin), (Australian, Karshenky, suvin and G93), (Australian, G70, suvin and G93) exhibited the best effected to forming the double crosses for position of first node, for days to first flower, days to first boll…”

Egyptian Journal of Agronomy http://agro.journals.ekb.eg/ 1343 G ENETIC materials used in the present investigation included five cotton varieties belong to (Gossypium barbadense, L.). Three of these varieties were long staple, BBB (big black boll) (P 1 ), Australian (P 2 ) and G97 (P 3 ) while the other two varieties were extra-long staple, Giza 92 (P4) and G96 (P5 ). Hybrids produced from these parents and the parents were evaluated in Sakha Agricultural Research Station, Kafr Al Sheikh Governorate, Egypt. Studied traits were; boll weight, number of bolls/plant, lint percentage, seed cotton yield, lint cotton yield, first fruiting node, days to first flower appearance, duration of the boll maturation, upper half mean (U.H.M), fiber strength and Micronaire value. Difference between single crosses and double crosses (DC) was highly significant for most studied traits. GCA mean squares in all studied traits were significant for F 1 except for days to first flower and fiber fineness (micronaire reading). GCA mean squares were significant for DC except for lint%, fiber length and days to first flower. A very important issue of double-cross hybrids is the arrangement of parents, i.e., order effect, in the hybrids.
