| Abstract | ||||
| This investigation was carried out at Sakha Agricultural Research Station, North Delta, Egypt, to study the relationship between yield components and lint yield and the contribution of boll weight, number of open bolls/plant, number of fruiting branches/plant, date to first flower appearance and plant height to lint yield in three Egyptian cotton cultivars , i.e. Giza 85, Giza 77 and Giza 76, during the two seasons 1994 and 1995. Using path coefficient analysis, ranks of the five factors contributing to lint yield per plant and their interaction differed. Number of open bolls had the highest direct effect for the three cultivars during the two seasons of study. It amounted to 34.68, 60.23 and 46.86% for Giza 85, Giza 77 and Giza 76 respectively. Moderate direct effect in both seasons were recorded for number of fruiting branches per plant for Giza 85 and boll weight for Giza 77 and Giza 76. | ||||
