Pant CMS3A Unique improved cytoplasmic genetic male sterile line with exerted panicles for potential hybrid seed production in rice
Author(s): MK Nautiyal, Leela Bhatt and Nidhi Bhatt
Abstract: Four cytoplasmic genetic male sterile (CMS) lines and their respective maintainer lines of rice were used in this experiment. The CMS lines included were the newly developed line Pant CMS3A along with other three existing CMS lines i.e. IR58025A, Pusa 6A and IR 79156A These were planted in four rows of 6 meter length along two rows of respective maintainer lines were also planted aside. The hybrid seed set under natural conditions was allowed without GA3 application and supplementary pollination. Observations were recorded on plant height, days to 50% flowering, number of tillers/plant, out crossing rate (%), panicle exertion (%), panicle length (cm), number of filled grains, total number of grains and yield (Kg/ha). The panicle exertion in Pant CMS 3A showed significant advantage over widely used CMS lines viz. IR58025A, Pusa 6 and IR79156A with respect to panicle exertion, out crossing rate and days to 50% flowering. If this line is utilized in the hybrid seed production, use of GA3 can be avoided and seed yield can be enhanced.
