COMPARATIVE STUDY OF FIBER PROPERTIES AND YIELD OF FIVE NEW EGYPTIAN COTTON CULTIVARS
Cotton Research Institute, Agricultural Research Centre, Giza, Egypt
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.
