Background:
Lack of uniformity in curd appearance alongwith maturity and low productivity are major limiting factor in early cauliflower. The hybrids showed better results in cauliflower for solving these problems. However, in self-incompatible lines the level of self-incompatibility (SI) always remains doubtful, hence, the Ogura sterile cytoplasm based CMS system is most reliable and affordable at present for hybrid breeding and production of hybrid seeds in cauliflower but it was not introgressed into early group genotypes of Indian cauliflower. Technology Details:
The DC 8441-5 is an Ogura sterile cytoplasm based cytoplasmic male sterile (CMS) line of early maturity group (25-30 °C) of Indian cauliflower. Its maturity period is middle of October. 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. . The new CMS line CMS 8441-5 is a step to solving the problems related to SI system and facilitate affordable hybrid seed production in cauliflower.
