Morphological and Agronomical Characters Identification of Rice Plant (Oryza sativa L.) Backcross1 (BC1F1) Pandan Ungu/Kambang//Pandan Ungu

The research was conducted to know percentation of the pertitization and morphological and agronomic character of paddy (Oryza Sativa L.) BC1F1 Pandan Ungu/Kambang//Pandan Ungu. Thwas research was conducted from January to December 2018 at the Screen House Agriculture of Faculty Mulawarman University. Thwas research used the castration backcross method between Pandan Ungu/Kambang females and Pandan Ungu males to produce BC1F1. The castration from 214 spikelets was obtained from 20 fertile grains (4,60%) from that seed only 10 seeds were to able germinate (50%) and only 4 plants (40%) were able to grow. Results showed Morphological characterwastics; number of productive tillers that have the criteria of medium (1 plant), slight (1 plant), and very few (2 plants); long panicles that have the criteria of medium (3 plants) and long (1 plant); the length of the seed that has the criteria was very long (4 plants); the width of the seed 2.5-3 mm (4 plants); and the thickness of the seed 1.6-2 mm (4 plants). On the Agronomic characters, plant height was short (3 plants) and high (1 plant); the kink of the rod has the criteria of somewhat strong (4 plants); the age of the plant has the criteria of very early maturing (4 plants); and weight of 100 grains of dry unhusked have 2,80 g (1 plant), 2,33 g (1 plant) and 2.28 g (1 plant). The achievement of Morphological characters and Agronomic practices, namely; the Length of the panicle following the character (Pandan Ungu) and (Kambang), the length of the seed following (Kambang), plant height following the character (Kambang) and the age of the plant follows the character (Pandan Ungu). As for new characters were obtained, namely; the number of productive tillers, the width of the seed, the thickness of the seed, the kink stem, and the weight of 100 grains of dry milled grain.
