General and Specific Combining Ability Studies for Leaf Area (LA) in some Maize Inbreed Lines (Zea mays L.) in Agroecological Conditions in Kosova

| description | In the methods of diallel crossing which are based on Hayman, (1954), Jinks,(1954), Griffing, (1956), Mather and Jinks, (1971), can produce values of hybrid combination and methods of heritage for a particular trait of selection. The use of heterosise in the world has started since the year 1933 in USA, where about 1% of the total surfaces were planted, while latter in the year 1953 the hetorsis of the maize hybrids was expanded up to 96% (Sprague, 1962). The cultivation of the maize hybrids started after the year 1960 in about 4.38%, and the seed was provided by the USA. Now, in Kosovo, about 95% of of surfaces are planted with different types of hybrids (Fetahu, 1998). The main object was to test and identify the reaction of some hybrid combinations of the F1 generation for leaf area (LA). Research includes 10 inbreed lines that had been in diallel crossing for GCA and SCA. The formula that provides the component of genetic variance was Griffings (1956) method 2, the mathematical model I.Xij= micro+gi+gj+sij+e. With maximal LA where heterozygote combination from inbreed lines was L6xL10, xg=788.6 cm 2, while minimal value was combination L4xL5, xgj=558.9 cm2. The experimental average value of F1 generation was micro= 678.8 cm2. With maximal and minimal average differences for LA of F1 generation were + 109.8 cm2 or 17%, respectively -119.9 cm2 or 18%, comparing with value micro. The total variability between genotypes were +/- 35%, with high significance. ANOVA for combination ability of GCA and SCA for LA provided with high phenotypes differences that were significant for P =< 0.05 and 0.01. Higher value for GCA obtained L2= +31.326, while with lower combination, the value was L4 = 38.069. For SCA with higher values had L6xL10= + 156.73, with high significance for P =< 0.01. |
