Induced mutations have proven flexible, workable and ready to use on any crop. In addition, it is a low-cost technology that has the ability to address current challenges in agriculture. The breeding of new mutant varieties with a higher yield potential will be the driving force to meet the challenges of the 21st century. High-yielding mutants were isolated from the M3 progeny of linseed varieties Indira Alsi and NL-115 treated with 0.1, 0.2, 0.3, 0.4 and 0.5 % EMS. Data on various quantitative traits, such as plant height, number of primary branches per plant, number of secondary branches per plant, number of capsules per plant, number of seeds per capsules, 1000-seed weight (g), seed yield (g) per plant, were recorded for 10 superior mutants in the M3 generation. The mutants were morphologically quite distinct, as compared to the control and to each other. The most notable change was increase in number of secondary branches and capsule numbers of these mutants, giving them high yield as compared to control. Mean performance of different quantitative traits was significantly better among the mutants as compared to the control, with a few exceptions.

Combining Ability Studies for Yield and Its Component Traits in Groundnut (Arachis hypogaea L.)

International Journal of Current Microbiology and Applied Sciences (2017)

K. Sudarshan Patil P.V. Kenchanagoudar Mohammad Rafeeq M. Kulmi

In the present investigation, three lines were crossed with six testers in L × T mating design to estimate the combining ability for yield and component traits in groundnut. Non-additive genetic variance played a preponderant role in the inheritance of majority of characters studied viz., primary branches, secondary branches, matured pods per plant, immature pods, kernel yield per plant, 100 kernel weight, shelling per cent, sound mature kernels, chlorophyll content, haulm yield per plant and oil content. Additive genetic variance was more for the plant height and pod yield. The line Dh-86 and tester AGL-635 were found to be good combiners and are considered as superior parents in the present study as they recorded high per se performance with positively significant gca effect. Among the 18 F1 s, crosses viz., Dh-86 × AGL-108, TMV-2 × AGL-168 and Dh-86 × AGL-635 were considered to be superior as they recorded positively significant sca effect for pod yield per plant.
