<p>The present investigation was carried out to study mutagenic effectiveness and efficiency of gamma rays and EMS treatments in Pigeon pea (Cajanus  cajan (L.) Millsp) Var CO-7. The relative effectiveness and efficiency of the both mutagen used was assessed from the data on biological damage in M1 generation and frequency of chlorophyll and viable mutants in M2 generation. The spectrum of chlorophyll mutants such as xantha, albino, chlorina and viridis, viable mutants like tall, dwarf, early flower, early maturity, late maturity, bushy, high yield and seed mutants were observed in both the mutagenic treatments.  Among the chlorophyll mutants xantha was found more in number. The mutagenic effectiveness and efficiency were found to be higher at 20KR of gamma irradiation and 25mM of EMS. The mutation rate of gamma rays was higher in terms of effectiveness than that of EMS. More number of chlorophyll and viable mutants was induced in gamma rays treatment when compared EMS treatment.</p>

Effectiveness And Efficiency

The traditional varieties of chick pea have low potentiality and restricted variability with respect to economic characters. Broadening the genetic base for crop improvement can be quickly achieved through induced mutagenesis. The present study was undertaken in order to comparing the effectiveness and efficiency of mutagens on Cicer arietinum. In this regard, Co – 4 variety of chick pea was subjected to different dose/concentration of Gamma rays (20, 30, 40, 50 and 60 kR) and Ethyl Methane Sulphonate (10, 20, 30, 40 and 50 mM) for inducing mutation. Mutagenic effectiveness and efficiency was calculated based on biological damage in M1 and chlorophyll mutations in M2. The results indicated that, mutagenic effectiveness increased with the increase in dose/concentration of mutagen. Intermediate treatments in general were found more efficient in causing less biological damage and inducing maximum amount of mutations. It shows that the chemical mutagens are more effective and efficient than physical mutagen for inducing mutation in Chick pea

Effectiveness And Efficiency

AbstractLegumes play a pivotal role in combating the chronic hunger and malnutrition in the developing nations and are also ideal crops to achieve global food and nutrition security. In the era of climate change, erratic rainfalls, depleting arable land and water resource, feeding the rapidly growing population is a challenging task. Among breeding programs for crop improvement, induced mutagenesis has proven to be the viable, effective, robust and coherent tool to facilitate the process of creating varieties with improved yield. Like most other pulses, cowpea is a self pollinated, nutritious, versatile and widely adapted grain legume, but harbour a little accessible genetic variability. Lack of sufficient genetic variability and small size of flowers, traditional plant breeding methods are not enough to meet the demands of improvement of cowpea. Hence, induced mutagenesis was employed to induce significant genetic variability across a range of agro-economical traits in two cowpea varieties Gomati VU-89 and Pusa-578 from M1 to M4 generations. The success of induced mutagenesis largely depends on the selection of appropriate mutagen, its dose, effectiveness and efficiency. Hence present study was conduct to assess the effectiveness and efficiency of single and combined doses of sodium azide and gamma rays to set an appropriate protocol for induced mutagenesis experimentation in cowpea.
