Performance of some flax genotypes, chemical composition of fibers, seeds and their relation to yield

Abstract

This investigation was conducted at Gemmiza Agric. Res. Station during the two successive winter seasons of 2014/2015 and 2015/2016 to study the differences among nine flax genotypes namelyline 541/D/10, Sakha 2, line 402/11/6, Sakha 3, Giza 9, Ilona, line 22, line 2467/3 and line 435/11.The experiments trails were carried out in Randomized Complete Block Design (RCBD) with four replications. Results revealed that the flax line 541/D/10 ranked the first and surpass the remain flax genotypes in biological yield/fad., straw yield/fad., fiber yield/fad., fiber %, fiber length, seed yield/fad., seed index, oil %, oil yield/fad., Iodine value, crude protein %, in seeds and total carbohydrates % in seeds. But this line occupied the fourth position concerning fiber fineness trait. The flax variety Giza 9 ranked second in all fiber characters, while line 2467/3 was the fewest in biological yield/fad., straw yield/fad., fiber yield/fad. and fiber percentage. The line 22 ranked second regarding seed yield/fad., oil % and oil yield/fad. The flax variety Ilona achieved highest estimates for cellulose %, moisture % in seeds and crude fiber % in seeds. On the other hand, Ilona gave the lowest estimates in seed yield characters. Correlation coefficient(r) values were highly significant and positive between fiber yield/fad. and each of biological yield/fad., straw yield/fad., fiber %, fiber length, fiber fineness, lignin % and waxes %. While it was significant and positive with each of cellulose %, and pectin %. The(r) values recorded highly significant and positive between seed yield/fad. and each of oil yield/fad., seed index, oil %, total crude protein % (in seeds) and total carbohydrates % (in seeds). While correlation coefficient(r) values were significant and positive with either Iodine value and crude protein% in seeds.
