A White Waxy Corn Hybrid with Lodging Tolerance, ‘Hayanchal95’

A ‘Hayanchal95’, a new waxy corn hybrid, is a single cross hybrid developed by the maize breeding team at the National Institute of Crop Science (NICS), Rural Development Administration(RDA) in 2011. This hybrid was made by crossing between seed parent KW44 and pollen parent KW35. Days to silking of Hayanchal95 was three days earlier than Ilmichal, a check hybrid. Ear length and diameter of Hayanchal95 were 18.3 cm and 4.1 cm, respectively. The ratio of kernel set length to ear length was 90% and lower than Ilmichal. Its quality characteristics like amylopectin content, hardness of kernels, and value of sensory evaluation were not significantly different from Ilmichal except grain length. Resistance to corn borer and lodging tolerance of Hayanchal95 were better than Ilmichal. The number of fresh ears was similar to those of Ilmichal and weight of fresh ears was lower than Ilmichal in regional yield trials (RYT) from 2009 to 2011. Although flowering time of its parent lines was good match during crossing between the seed and pollen parents, seed production was low. It is adaptable to the whole country. Plant variety protection right of ‘Hayanchal95’ was registered in July 2014, and its grant number is 5110.
