| Abstract | ||||
| Two field experiments were carried out at Sakha Research Station in two successive seasons; 1997 and 1998 to study the variation and correlation of some new Egyptian varieties in yield components, tech-nollogical, chemical and yam strength. Five Egyptian cotton cultivars were included in this study, two of them belong to the extra-long staple category i.e. Giza 87 and Giza 88, and three belong to the long staple category i.e. , Giza 85, Giza 86 and Giza 89 The effect of genotypes was highly significant for the studied traits except for lint sugar and wax percentage. • The effect of different growing season was significant for all studuied traits except seed index, SO% span length, Presely index, cellulose and wax percentages. The effect of interaction between cotton cultivars and growing season was significant for seed index, 2.5 % span length, micronaire reading, hair weght, Presely index, cellulose %wax % and yam strength. Positive significant correlations were found between seed cotton yield, lint cotton yield woith boll weight/g, lint percentage, maturity ratio, hair weight and yarn strength-boll weight/g with lint percentage, seed index, micronaire reading and cellulose % maturity ratio with seed index and lint strength. Also, positive interrelationhips were found among 2.5%, 50% span length with micronaire reading, fineness, hair weight, and yam strength-yarn strength with wax % and sugar %. Negative correlations were recorded between lint span length and boll weight, seed index, lint percentage and cellulose % -Presely index and lint percentage. | ||||
