Descriptions of near-isogenic lines of inbred Hi27

摘要

The following near-isogenic lines (NILs) of Hi27 have been developed in Hawaii through 6 or more back-crosses (BCs). Hi27 is a hard yellow flint of tropical origin from inbred CM104 (India) that was Colombian Amarillo Theobromina in origin, which we converted to Mv gene (3L-78) for resistance to maize mosaic virus (Brewbaker, Crop Sci 37:637, 1997). It is of medium height (2m) and mid-maturity (60 days to silk) (Fig. 1). Hi27 has bronze anthers on reddish glumes, pink silks, red blush on lower stems, and colorless seedlings and coleoptiles.
