Study on waxy corn XIII. Botanical characteristics and crude incomes analysis of Daedukchal 1

Abstract

Daeduckchal 1 waxy corn hybrid including check was planted and compared with domestic leading vatiety on agronomic characteristics, traits related to table gualities and crude income. Stem and ear height of Daeduckchal 1 among used hybrids were intermediate and stem diameter was also similar to other hybrids. Days to tasseling of this hybrid needed 56 days which was slightly shorter than check hybrid, Yeonnong. Ear length of CNU-H2 was longer than Yeonnongchal as 21.7 cm, while Chalok 2 was 14.1 cm. Number of tillers per plant of this hybrid were higher than Chalok 2 but lower than Yeonnong. Pericarp thickness of CNU-H2 and CNU-H3 were similar to Yeonnon. In sugar content, Daeduckchal 1 was intermediate level as 11.7 brix(%). Marketability of Daeduckchal 1 was the highest among used hybrids and crude incomes was also high.
