Abstract
Based on the nutrition importance of nut squash seed and its commercial value, an experiment has been conducted in randomized complete block design with 30 squash landraces collected from West Azerbaiejan, Golestan, and Isfahan Provinces with three replications at Minab Agricultural Research Station during 2018-2019 and 2019-2020. It tried to compare seed yield and yield components of different nut squash genotypes in autumn planting time of Hormozgan Province. The field was prepared in August and the seeds were sown in late September. The evaluated characteristics included plant length, the number of fruit in the plant, average fruit weight, fruit length and width, fruit yield, seed yield, the weight of 100 seeds, hollow seed percent, kernel percent (kernel/seed ratio), and seed bitterness percent. According to the results of the important traits such as seed yield, seed size, hollow seed percent as well as kernel percent, the genotypes Kh6, Kh5, CP7-A, Kh2 selected CP3, CP4-B self, CP7-B self, Isfahan Pumpkin, CP4-E, O6, CP2-B, and N2 have had more suitable status than others. By evaluating all examined parameters and based on the production costs and net profit, there is the possibility of nut squash planting in Minab region with some genotypes including the collected genotypes from Khoi region including Kh6, Kh5; the genotypes in Golestan province including CP7-A, CP7-B-Self, CP4-E, and CP2-B; Isfahan Pumpkin.
