2012 Annual Report
1a.Objectives (from AD-416):
The primary objective of this proposal is to develop improved lentil varieties. Sub-objectives include making crosses between elite lentil breeding lines and screening breeding materials for disease resistance, seed protein content and seed mineral concentration.
1b.Approach (from AD-416):
Cross will be made in the greenhouse and the field between elite lentil lines and varieties. Parental lines will be selected based on performance in preliminary and advanced yield trials for a range of agronomic traits including seed size, yield, plant height and tolerance to lodging. Hybrids are increased in the greenhouse and subjected to multiple cycles of self pollination to produce segregating bulk populations. Segregating bulk populations (F3-F6) will be grown in the field and selected for seed type (size, shape and color), height and lodging tolerance, and early maturity. Preliminary selections will be evaluated in the field at a single location. Advanced selections will be evaluated in yield trials conducted at multiple locations. Breeder seed will be produced from several elite breeding lines for subsequent varietal releases. Preliminary and advanced breeding lines will be screened for resistance to Aphanomyces root rot, seed protein content, and seed mineral concentration.
This is the final report for the project 5348-21000-024-21T, which terminated in December 2011. Substantial results were realized during this project. Spring sown lentil breeding lines and varieties were evaluated over multiple locations in Washington, Idaho, Montana, and North Dakota. Elite lines with high yield and desirable seed traits were identified for Spanish Brown, Eston, Turkish Red, Zero-tanning and Large Green market classes. A new Spanish Brown lentil variety, “Morena” was released as a result of evaluations conducted during this research project. Two other exceptional lentil lines, LC01602273E and LC01602300R, were identified that consistently produced yields that were 20% higher than yields for the respective check varieties Eston and Richlea. Breeder seed has been produced for these lines, which are being considered for release as new varieties that are especially adapted for production in the US Northern Plains and evaluated over 2012. Lentil breeding lines were also evaluated for winter hardiness across several locations in Washington. One line of particular interest has been identified, LC03600232WT, which yields similar to the check variety Morton and also had the oval shape and dark orange seed color required for Turkish Red lentils. In addition, seeds of LC03600232WT are larger and wider than sees of Morton, which makes the line a promising candidate for release as a lentil that can be sown in the fall and then decorticated and polished prior to marketing. New populations have also been made to develop winter hardy lentils in other market classes and additional winter hardy lines have been identified. The results of this project relate to Subobjective 1A (Develop pea, lentil and chickpea cultivars with broad adaptation to diverse production environments and with resistance to fungal and viral pathogens) Subobjective 2A (Develop winterhardy cultivars of pea and lentil with edible quality traits that are adapted to direct seeding) of the in-house project.
