KK 15-36-C & Ayung, two modern high yielding rice (Oryza sativa L.) varieties for irrigated lowland ecosystem of Papua New Guinea

Abstract

Rice Breeding and Agronomic Research Programme, initiated during 1991, has been successful in identifying suitable varieties for Irrigated Lowland, Upland, High Altitude areas with Cool Climate and Acid Soils (P deficient) Ecosystems-oriented entries of INGER Nurser­ies of IRRI. We developed most promising genotypes by practising very stringent selec­tion. At the moment we have developed a wealth of gene sources, which have enhanced our capability not only to directly commercialize some of these varieties but also to use as
donors for introgression. In this article we will consider the selection of two varieties extremely suitable for Lowland Ecosystem.
