Registration of CA0469C025C Chickpea Germplasm

Abstract

Chickpea (Cicer arientinum L.) germplasm CA0469C025C (Reg. No. GP‐295, PI 672149) was released by the USDA–ARS in 2010 based on its improved seed yield and reaction to Ascochyta blight (caused by Ascochyta rabiei) relative to the commercial cultivars Dwelley, Sierra, and Sawyer. CA04690C025C is an F7–derived line from the cross ‘Obraztsov Chiflik 1’/‘Sanford’. CA0469C025C was tested in advanced yield trials for 16 location‐years in the U.S. Pacific Northwest (Idaho and Washington) and four location‐years in Montana. In Washington and Idaho, CA0469C025C averaged 1636 kg ha−1, which was 17, 17, and 7% greater than Dwelley, Sierra, and Sawyer, respectively. In trials conducted in Montana, CA0469C025C averaged 1403 kg ha−1, which was 39, 28, and 13% greater than Dwelley, Sierra, and Sawyer, respectively. The plant height index of CA0469C025C is similar to that of the three check cultivars, indicating good lodging tolerance. CA0469C025C and check cultivars were screened in field nurseries for reaction to Ascochyta blight using a scale of 1(highly resistant) to 9 (highly susceptible). The mean reaction of CA0469C025C over 4 yr was 3.6 compared with 5.7, 4.7, and 4.3, respectively, for Dwelley, Sierra, and Sawyer, indicating CA0469C025C has better resistance to Ascochyta blight. CA0469C025C produces seed that is too small for canning or fresh markets, but it will be useful as a parent for breeding efforts to increase yield and disease resistance in chickpea.

Genotype and Environment Effects on Prebiotic Carbohydrate Concentrations in Kabuli Chickpea Cultivars and Breeding Lines Grown in the U.S. Pacific Northwest

“…Minor genotype effects, or in many cases a lack of significant genotype effects are likely due in part to the relatively narrow genetic base present in the examined chickpea cultivars and breeding lines ( Table 1). Three breeding lines are full-sibs derived from CA0469C020C/Dwelley and seven breeding lines share as a parent CA0469C020C, which has resistance to Ascochyta blight and is a full-sib line to CA0469C025C, a germplasm with improved disease resistance and high yield (Vandemark et al, 2014b).…”

Crop Performance Evaluation of Chickpea and Dry Pea Breeding Lines Across Seasons and Locations Using Phenomics Data

“…The Palouse region, which includes parts of eastern Washington, northern Idaho, and northeastern Oregon, is one of the largest producers of pulse crops in the United States ( USDA-NASS, 2020 ) and is home to several pulse breeding programs. Pulse breeders have developed and released multiple pea and chickpea cultivars with better seed yield, quality, and improved disease resistance ( McGee and McPhee, 2012 ; McGee et al, 2012 , 2013 ; Vandemark et al, 2014 , 2015 ; USDA-ARS, 2018 ). However, plant breeders have primarily relied on traditional methods to collect phenotypic data on breeding lines.…”
