Abstract:

An experiment was conducted during the rainy (kharif) seasons of 2002 and 2003, in Gujarat, India, to identify Spanish groundnut genotypes with high yield potential and improved water use efficiency. Considerable variation was observed among groundnut genotypes for specific leaf area and SPAD chlorophyll meter reading, both indicators of water use efficiency. Of the 17 Spanish-type advance cultures studied, one culture, i.e. 'PBS 12160', gave significantly higher pod and kernel yields with 49.2% oil content. It recorded an 18.7% higher pod yield over the national control 'JL 24'. This genotype also possessed a short plant stature and high number of secondary branches. Low specific leaf area and high SPAD chlorophyll meter reading was observed for this genotype, indicating its potential suitability in situations where water availability is limited or under rainfed conditions.
