Evolution of new wheat variety NIA-Amber for the general cultivation in Sindh province - a case study

摘要

A new wheat variety NIA-Amber developed by NIA Tando Jam has been released by the Government of Sindh in the year 2010. NIA-Amber possesses semi-dwarf stature with high tillering capacity endowed with high grain yield, early maturity, better grain quality and resistance to lodging. It possesses the highest protein content (16.02%), highest wet gluten (37.1%), high dry gluten (12.0%), and high SDS value (28.5). It confirmed its superiority in grain yield in series of trials such as preliminary yield trials (PYT), advanced strains yield trials (AST), comparative yield trials, micro yield trials, zonal trials and national trials. It showed stability and wide adaptation over different environments in province of Sindh. It performed well under normal and late conditions. It showed increase in yield with addition of zinc in combination with other fertilizers NPK. The variety showed resistance against leaf rust and tolerance to yellow rust diseases. In NUWYT, it produced higher grain yield and ranked first in Sindh under late sowing conditions; whereas, it acquired 6thposition in NUWYT under normal sowings. The variety has the potential yield of 6406 kg/ha. Its release will make a significant contribution to genetic diversity and enhance the stability of yield, which will ultimately improve the socio-economic conditions of the farmers of the province of Sindh.
