Advances in Breeding Methodologies to Develop Resistance Genes against Blast: A Review (Published)

Finger millet is still neglected cereal crop mostly grown and consumed by resource-poor people mainly in arid and semi-arid tropics. The projected food demand of the global population will pressure plant breeders to secure the demand by improving the yield of major cereal crops. To meet this demand, there is a consistent need to look beyond the conventional farming system to increase production and productivity in sustainable ways. However, finger millet production and productivities are limited by many factors namely biotic and abiotic. Of biotic factors, finger millet blast disease is the most limiting factor. The disease is caused by the filamentous ascomycetous fungus called Magnaporthe oryzae. Under favorable conditions, the pathogen can devastate the entire field in all finger millet growing regions. Moreover, the frequent breakdown of blast resistance causes significant yield losses worldwide. The utilization of innovative and efficient research strategies guarantees future sustainable production of finger millet. Therefore, exploring an advanced breeding methodologies presently being used and discussing future directions for development of blast resistant varieties will help providing a broad understanding concept for finger millet breeding.

Ammi Model Analysis of Stability and Adaptability of Finger Millet (Eleusine Coracana) Genotypes in Southern Ethiopia (Published)

Multi-location study was conducted at locations namely Jinka, Kako and Alaba in two consecutive years (2011 and 2012 G.c) to identify high yielding, disease resistant/tolerant and stable performing finger millet genotype for potential areas of Southern region. The trails were arranged in a randomized complete block with three replications. Tadesse was used as standard check along collections screened (Six finger millet genotypes). The experimental plot size for was 5mX 7.5(37.m2).  The spacing between rows was 45 cm and 15 cm between plants after thinning.  The standard agronomic practices were applied equally according to local agro-ecological conditions. The grain yield in qt/ha with 14% moisture was measured. Additive Main effect and Multiplicative Interaction (AMMI), Genotype and Genotype by Environment interaction (GGE) biplot analysis model revealed that environment effects and genotype effects were highly significant implies environments are diverse and genotype were performing differently. According genotype LR004 &LR005 showed stable and above mean performance across testing location and season. So this varieties should taken for verification trial with standard checks (recently released varieties) under locations were regional variety trials were conducted.
