ABSTRACT
ICP 8504 is a pigeon pea accession widely used in breeding programmes for incorporating higher seed number per pod. However, for the first time pods with 10 well-developed seeds were recorded in germplasm accession ICP 13828, though only 3 pods with 10 seeds were found from different plants grown on a 9-m row. ICP 13828 is a field collection from St. Patrick's in Grenada during an ICRISAT-initiated germplasm expedition in 1985. This accession was characterized for different morpho-agronomic traits during the 1986-87 rainy season at Patancheru, Andhra Pradesh, India. ICP 13828 is semi-spreading with indeterminate flowering habit, with 129 days to 50% flowering and 174 days to maturity. Plants grew approx equal to 130 cm tall and on average produced pods. Pods were long and flat with mixed (green and purple) pod colour. On an average, 5.7 seeds per pod were produced. The seeds were cream-coloured and medium-sized (12.1 g/100 seeds) with seed protein content of 20.7%.
