| Abstract | ||||
| Fifteen genotypes of pumpkin (Cucurbita moschata Duchesne) were screened for earliness and fruit yield at the Experimental farm, faculty of Agriculture, Sohag University during the two successive seasons; 2007 and 2008. There were significant differences among genotypes for all studied characters. Etamp cultivar had the longest vine length and leaves number per plant, while Butternut cultivar had the shortest vine length in both seasons. Butternut cultivar gave the highest value of sex ratio, while the lowest one was recorded by El-Mansoura cv. Butternut cultivar was the earliest in both male and female flowers, while genotype Khartoum (Sudan) accession was the latest in male and female flowers in both seasons. Etamp cultivar bore the first male and female flowers on the highest node number, while Butternut cultivar produced the 1st male and female flowers on the lowest node number in both seasons. Pepa (Beni Suef) accession had the highest number of nodes between the 1st male and 1st female flowers while; Butternut cultivar had the lowest number of nodes between the 1st male and the 1st female flowers in both seasons. Desuk (Kafr El-Sheikh) accession gave the largest number of days between the 1st male and the 1st female flowers anthesis, while Butternut cultivar gave the lowest number of days between the 1st male and the 1st female flowers anthesis. Butternut cultivar gave the highest sex ratio, while El-Mansoura accession gave the lowest sex ratio in both seasons. Etamp cultivar fruits were longest, while those of accession Omdurman (Sudan) were shortest in both seasons. Etamp cultivar was greatest in fruit diameter, while Butternut accession was smallest in fruit diameter in both seasons. Etamp cultivar was heaviest fruit weight, while Butternut cultivar was lowest in fruit weight in both seasons. Etamp cultivar gave the highest value for flesh thickness while, Butternut cultivar showed the lowest value for this character in both seasons. Etamp cultivar exceeded all other genotypes in total fruit yield, while Butternut cultivar produced the lowest fruit yield in both seasons. Butternut cultivar gave the highest value for total soluble solids%, while Bardis (Sohag) accession showed the lowest value for this character, in both seasons. Thus, the results of this study could be useful in breeding programs for improving local pumpkin genotypes under Upper Egypt conditions. | ||||
