Abstract

The aim of the experiment were to rejuvenate and characterize of wheat germplasm. Eighty nine genotypes planted at Kuningan Field Research Instalation, West Java from June to October 2002. Plot size for each genotypes 3 x 1 m2 with spacing 25 x 10 cm. Seeds were planted with 2 seed per hole and thinned out to one plant. Several agronomic characters were observed: date of flowering, date of maturing, plant height, number of productive tiller per hill, seed weight per hill and yield per plot. The results showed that: date of flowering (mean 60.9 days with range 48-77 days), date of maturity (mean 102.7 days with range 87-119 days), plant height (mean 72.4 cm, range 53.5-88.7 cm), number of productive tiller per hill (mean 9.71, range 4.9-24.0), seed weight per hill (mean 11.96 g, range 5.3-34.5 g) and seed yield per plot (200.0- 2624.5 g). Seventeen genotypes have date of flowering <54.3 days, some of them were H40, H80, V219, and V132. There were 25 genotypes have date of harvesting ranged 87-98 days, some of them were H40 (87 days), H85 (91 days), H90 (91 days). There were 16 genotypes have plant height <65.2 cm, some of them were C3 (53.5 cm), C7 (58.4 cm), C14 (59.1 cm). Whereas the highest was C10 (88.7 cm). Nine genotypes have number of productive tiller per hill >17.5, some of them were C8 (23.6), C27 (22.7) and the greatest number was C28 (24.0). Sixty six genotypes have number of productive tiller per hill, ranged 4.9-11.2, some of them were: C34 (4.9), C24 (5.2), H85 (5.6). Seed weight per hill showed that 60 genotypes have seed weight <12.6 g, for example: H71 (5.3 g), H40 (6.6 g), C132 (5,4 g), C34 (6,7 g), whereas the heaviest was C28 (34.5 g). Sixteen three two genotypes that have yield per plot >2000 g were V192 (2016.0 g), and V167 (2624.5 g).
