Offered this girl a rat for the first time tonight. She wolfed its down. One of the pos het anerys. When shes up to size we plan to put her dad Hersheys over her. The aim is to get more visual anerys as this is a yet unproven mutation in morelia. Any visuals will be outcrossed to unrelated pure coastal carpets to strengthen the line.

Plant biotechnology: deals with insertion of desirable characteristics into plants through genetic modifications for the purpose of creating beneficial plants. Plants which are modified genetically are termed as Transgenic plants.Transgenic plants usually are created by modifying their DNA to serve different…

Urginea indica Kunth commonly called as Jangli Pyaz or jangli dungli is a medicinal plant having very high therapeutic value. Due to over exploitation, it has become vulnerable in some places. So, development of genetically advanced varieties of this plant is needed so that we can avail the benefits of this plant for a longer period of time, with great ease to mitigate several human ailments. To develop such variations in the plants through mutation breeding, screening of the plant is the most important aspect. Therefore, in this research sensitivity of Urginea indica Kunth to Ethyl Methane Sulphonate was assessed through the measurement of the mutagenic effects on pollen grains. Dose dependent decrease in the pollen fertility was observed. In addition, variation in the shape and size of the pollen grains were also observed after treatment with different concentrations. Thus, Urginea indica Kunth was found to be sensitive to Ethyl Methane Sulphonate.

Abstract

A total of thirty nine M3 and thirty seven M4 maize lines derived from mutation breeding were evaluated for variation in agro-morphological traits at Jomo Kenyatta University of Agriculture and Technology, Farm, Juja from October 2014 to September 2015 to identify desirable mutants for use in plant breeding programmes. The experimental design was randomized complete block design in triplicates. During growth data on days to anthesis and silking, flag leaf width and length, number of leaves above upper ear, harvestable ears plant-1, diameter of the ear, days to maturity and grain yield plant-1 were recorded. Data were analyzed using Genstat 14th edition and the means separated using LSD at 5% level of significance. Results showed significant variations for grain yield plant- 1, herbicide tolerance days, days to anthesis and silking, pollen shedding and flag leaf width among the assessed maize lines.The recorded variations among maize lines suggested that there existed appreciable variation that could be utilized in breeding. Grain yield plant-1 was significant and negatively correlated with tolerance days. Grain yield plant-1 and herbicide tolerance cannot be improved simultaneously and the breeder should decide which trait to improve. Overall, the results indicated that induced mutation could serve as a source of variations for use in the improvement of maize.

Scared of Gen-Technology? A bit late for that!

Gen-Technology sounds already suspicious. I can not really say that I trust in this type of science. Too much missing knowledge (maybe it’s only me). Sounds like a bunch of kids with a magic box.

But you don’t have to go that far to hear scary stuff. If I would have know before how some stuff in the supermarket was produced I would never have bought it. Like products created by the common method of mutation breeding. By a radioactive transmitting device in the middle of a field gens are changed by chance. Hups, there the transformed wheat has the perfect Pasta (Barilla) preferences. Hups, what a nice looking grapefruit, lets call it Rubie red….

Apparently the DNA of a tomato is pretty similar to the DNA of humans. I guess that explains a lot.
