Objective:
To increase seed protein concentration in yellow pea cultivars. Determine the genetic variation of protein and mineral nutrient concentration in current cultivars of yellow pea (G x E) by growing lines in two replicated field trials in Montana.
Approach:
Objective 1. Determine the genetic and environmental variation of protein and mineral nutrient concentration in current cultivars and advanced breeding lines of yellow pea.
Field Experiment: A field study of 30 current and advanced breeding lines of yellow pea cultivars will be planted using a RCB design with four replications on 2022 field season. Soil tests will be conducted each year and standard practices for herbicide and pesticide applications will be followed. Agronomic data will include plant density, plant height, days to flowering and maturity, seed size and seed yield. Harvested seed will be analyzed for protein concentration, total starch, crude fat, moisture, ash, and total fiber using near infrared (NIR) spectrometry (NIR Matrix-I Spectrometer)]. Mineral nutrient concentrations will be determined using inductively coupled plasma mass spectrometry (ICP-MS) at WSU Core Facilities. Expected results: We expect to understand the stability of current and future yellow pea cultivars for seed protein and mineral nutrients and prepare extension bulletins for growers and processors.
