| Abstract |
Two field trials were carried out at Giza Agric. Res. Station farm during two successive seasons 1998 and 1999 to study yield, yield components, chemical composition of fibers, genetic variability, phenotypic correlation and stem anatomy of seven genotypes of Corchorus capsularis and two of Corchorus olitorius.
Results obtained can be summarize as follow:
1. The jute strain IRC321 ranked first and was superior to other genotypes in plant height, fiber yield and fiber percentage, followed by IRC212, But the lowest performance was obtained by S25 (C. olitorius).
2. The strain 25 achieved highest mean values in fruiting zone length, no of capsules/
plant, no of seeds/plant and seed yield, followed by S1, while the lowest estimates of these characters were obtained from UPC 94.
3- The genotype of UPC 94 recorded maximum cellulose ratio with minimum pectin and lignin percentages. On the other hand, the fiber of S25 contained highest pectin
and lignin ratios.
4- Phenotypic and genotypic variances were high in no of seeds/plant, seed yield/feddan, fiber yield/feddan, green stalk yield/plant, no of seeds/capsule, plant height and fiber length. But the minimum variances were found in seed index, pectin percentage. Fiber percentage and stem diameter.
5- The estimates of phenotypic and genotypic coefficient of variance in addition to genetic advance expected from selection were high for no of seeds/plant, no of capsules/ plant, seed yield/ plant, green stalk yield/plant, and seed yield/feddan. Mean while, the low estimates observed in technical stem length and stem diameter. Moreover, heritability in broad sense showed high values in most characters under study.
6-The phenotypic correlation coefficients between technical stem length and fiber yield/plant was highly significant and positive, while the association with stem diameter was non- significant and positive in all jute genotypes studied. The relationship between seed yield/ plant and each of no of capsules/ plant and fruiting zone length appeared highly significant and positive in all jute genotypes.
7- Microscopic observation indicated that IRC 321showed the highest number of fiber cells/cross section, but the lowest number obtained from S25. The same trend obtained by the fiber area/cross section among the nine jute genotypes. Moreover, the fiber index(cm3) agreed with results, which observed in fiber yield/ plant and in similar descending arrangement according to the superiority.
It is therefore concluded that IRC 321was superior to all jute genotypes studied in fiber yield and fiber percentage. Thereby, it most be recommend for cultivating area extension from this jute genotypes, concerning its highly fiber yield which consider as more economical product in comparison with the seed yield.
