“…They observed that the interaction between genotypes and years had a highly significant effect on seed cotton yield. Conversely, it was not significant for the seed index [13]. The mean square for the interaction between genotypes and years was highly significant for the earliness index, seed index, and seed cotton yield.…”

The fiber quality properties of Egyptian cotton should be improved to meet the increasing demand for it and competition with other natural and synthetic fibers. Cotton breeders faced many challenges in combining high yield, fiber, and quality properties due to the negative correlation between high yield and fiber quality in Egyptian cotton [1]. The cotton breeding program aims to produce new varieties characterized by early maturity, resistance to diseases, tolerance to drought, and salinity. Also, it gave a high lint percentage, high seed and lint cotton yields, and high quality properties (fiber length, fiber strength, fineness, yarn strength, and evenness). Improving seed cotton and lint cotton yield is one of the important objectives of any cotton breeder [2]. Giza 97 gave higher seed and lint cotton yields, a high lint percentage, and better fiber and yarn quality properties as compared with other varieties under study. Therefore, Giza 97 achieved the targets of farmer, trader, and spinner [3]. The promising cross (10229 x Giza86) gave higher seed and lint cotton yields and earliness indexes than Giza 86. Also, it has resistance to Fusarium diseases [4,5].Significant differences among genotypes for seed cotton yield were reported [6]. The effect of years on boll weight, seed index, seed and lint cotton yields, and fiber strength (g/tex) was significant, but not significant for lint percentage, micronaire reading, and fiber length. Also, the interaction between genotypes and years had a significant effect on boll weight, seed index, seed cotton yield, and lint cotton yield. On the other hand, it was not significant for the lint percentage [7]. Moreover, the effect of interaction between genotypes and years was highly significant for boll weight, lint cotton yield, and lint percentage. Conversely, it was not significant for seed index, micronaire, and fiber length [8]. It was stated that the effect of years on boll weight, lint cotton yield, lint percentage, and earliness percentage were significant. On the contrary, it was not significant for seed cotton yield. There were significant effects of the interaction between genotypes and years on seed index, seed cotton yield, fiber strength, and fiber length. Meanwhile, it was not significant for boll weight, earliness, lint percentage, lint cotton yield, micronaire, and uniformity ratio.[9] It was indicated that the interaction between
