Attempts to Develop Double Haploid Line through Anther Culture in Cauliflower

Early cauliflower is the rising demands of farmers in Bihar and adjoining state, therefore, the University has already developed one early cauliflower variety named Sabour Agrim, an Open pollinated variety (OPV). Besides, OPV, Hybrid of this crop is the need of hours particularly in this state. The breeders are utilizing self Incompatibility (SI) trait in cauliflower for the development of hybrids and even few hybrids have already been developed using this SI system. The advent of suitable male sterility techniques has given pace to the hybrid

development in cauliflower. However, development of inbred lines in cauliflower is a major constraint as it is associated with Self Incompatibility. On the other hand manual crossing is not only tedious but also time consuming. Production of double haploid (DH) lines is a viable option and is being used intensively in other crops too. Parental lines development through DHs has advantage over traditional inbreeding process as it obviate the needs of repeated selfing and consumes very less time. Commercially it is being produced either through anther culture or

microspore culture. The standard protocol is already developed for temperate cauliflower, cabbage and broccoli. Therefore, the team of researchers comprising Dr. Chandan Roy, Plant Breeder; Dr. Ravi Kesari, Biotechnologist, Mr. Vikash Kumar Jha, Research Fellow and Miss Swati Priya, Post Graduate Student, Bihar Agricultural University has stepped forward and are hopeful to increase the efficiency of callus induction for the regeneration of haploid line of early cauliflower through anther culture technique. Sabour Agrim and adopted early cauliflower variety Hazipur local are being used as a source for explants. 11-12% of used anthers have shown responsiveness towards callus development in this experiment till now.

Disbudding: A method to minimize the injury caused by Horn

Disbudding is the process of removing the horn buds from young animals at an early age. It cauterizes and thus destroys horn buds before growing into horns. Cattle, sheep, and goats are sometimes dehorned for economic and safety reasons. Dehorning is the process of removing the fully-grown horns of livestock. It is removed because it can pose a risk to humans, other animals and to the bearers of the horns themselves (horns are sometimes caught in fences or prevent feeding). Dehorning is not performed routinely, because it is a difficult process and painful for animals. Farmer should disbud their animals during young stage, because at this stage the process is quick and easy. Disbudding minimizes discomfort and risk, and is performed by several methods when horns are small "buds". Cauterization is the process of killing the growth ring of the horn using heat and

is usually done with the help of dehorning hot iron after the area is numbed with local anesthesia. This is done when calves are 3-4 week old. A curved knife can be used to cut the horn off when the calf is younger than a couple of months old. It is a simple procedure where the horn and the growth ring are cut off. The most recent development in dehorning technology is the use of a Caustic Potash (KOH) dehorning stick. The stick is used to rub around the horn bud in circular motion when livestock are below ten days old. The hair around the horn is trimmed back and the paste is spread all over the horn bud and around the base of the horn on the growth cells thereafter. The paste kills the growth

ring of the horn and then the horn falls off like a scab when it is healed. However, this method bears a risk of the paste causing injury to the animals’ eyes or other tissues if used during periods of rain. More information about rearing of calf may be obtained from Dr. Amit kumar, In-Charge, Dairy Unit, BAC Farm, Sabour.

World Environment Day, observed at different Unit of the University

World Environment Day has been observed at different Unit of the University on 5th June. Students, faculty members and Staff members of BPSAC Purnea, observed this Day under the leadership of Dr. Rajesh Kumar, Associate Dean-cum-Principal. Students of this college planted a sapling under the operation “One Man One Plant”. “Role of plants in removing pollution” was also well discussed to deep root its importance in youngsters’ mind. This programme was arranged by the courtesy of Dr. Pankaj Kumar Yadav, Asstt. Professor, Soil Science and his team, NSS Programme. In other instances KVK, Banka also observed this day at Banwasi Tasar kKit Palak Cooperative Bhawan, Lilawaran (Inarawaran) of Katiyari Pancahayat. Programme coordinator planted mango plant in cooperative bhawan and conducted a Kisan gosthi in which more than 40 Schedule tribe farmers participated.
