Background:
Lack of uniformity in curd appearance along maturity and low productivity are major limiting factor in mid-early group of Indian cauliflower. The hybrids showed better results in cauliflower for solving these problems. However, the level of self-incompatibility (SI) is doubtful particularly in mid, hence, the Ogura sterile cytoplasm based CMS are reliable, stable and affordable genetic mechanism for hybrid breeding. Technology Details:
The DC 8409 is an Ogura sterile cytoplasm based cytoplasmic male sterile (CMS) line of mid-early maturity group (20-25 °C) of Indian cauliflower. Its maturity period is middle of November to Middle of December months. The flowers of the CMS line are medium in size, light yellow, have normal ovary and well developed nectaries. It is good combiner for earliness and curd yield and good seed yield make it suitable for use in hybrid breeding.
