Evaluation of groundnut (Arachir hypodaea L.) lines for their yield potential and adaptability under rainfed conditions
Abstract
Evaluation of high yielding and newly developed groundnut lines is important to boost its yield in the country particularly in barani areas. As groundnut is mainly cultivated in barani or rainfed tract of the country therefore, it is necessary to evolve new genotypes to cope with changing environment. The objective of this research was to evaluate and access the yield and yield parameters of eight groundnut lines (six entries and two check varieties i.e. BARI-2011 and Golden) and their genetic advance and heritability and correlation among different traits during crop growing seasons of 2014 and 2015 at Groundnut Research Station Attock. Crop was grown under rainfed conditions and was harvested at physiological maturity. Data were collected for different yield and agronomic characters. A high variation was observed among the lines for agronomic traits. Groundnut advance line 10AK016 showed maximum pod yield (4.0 tonnes ha-1), grain weight (63 g) maximum shelling percentage (70) and number of seeds per pod (2.5).Values of heritability and genetic advance were 0.87 and 10.3 for pod yield, respectively. Different yield attributes such as maturity %, grain weight, shelling percentage and pod length has strong positive correlations 0.84, 0.73, 0.59 and 0.6 respectively with pod yield. Groundnut advance line 10AK016 can be approved as groundnut variety for general sowing in rain fed areas of Pakistan.
