"Stability of soil plant analytical development (SPAD) chlorophyll meter reading (SCMR) and specific leaf area (SLA) and their association across varying soil moisture stress conditions in groundnut (Arachis hypogaea L.)"^^ . "The complex nature of physiological\r\ntraits associated with drought tolerance and the\r\ndifficulties associated with their measurements in\r\nsegregating populations and large number of genotypes\r\ninhibited their use in the past in developing\r\nwater-use efficient genotypes in breeding programmes.\r\nWith new knowledge of easily measurable\r\nsurrogates of transpiration efficiency (TE), a\r\ntrait associated with drought tolerance—specific leaf\r\narea (SLA) and soil plant analytical development\r\n(SPAD) chlorophyll meter reading (SCMR), it is\r\nnow possible to integrate TE through the surrogates\r\nin breeding and selection schemes in groundnut\r\n(Arachis hypogaea L.). As a noninvasive surrogate of\r\nTE, SCMR is easy to operate, reliable, fairly stable\r\nand low cost. However, in a large-scale breeding\r\nprogram, it is difficult to complete SCMR observations\r\nwithin a specified time. The present study\r\naddressed the issue as to what extent the SCMR\r\nmeasurements can be spread over time by evaluating\r\n18 diverse groundnut genotypes for two physiological\r\ntraits, SCMR and SLA in two postrainy (Nov–Apr)\r\nseasons (2002/2003 and 2003/2004) in India. Observations\r\nwere recorded at different times during and\r\nafter the release of moisture deficit stress. There was\r\ngeneral agreement in genotype and trait performance\r\nin both the seasons. Interaction between SCMR and\r\ntime of observation was significant in only one season\r\n(2002/2003) but its variance relative to genotypes and\r\ntime of observation was very small. ICGV 99029 and\r\nICR 48, which recorded higher SCMR and lower\r\nSLA values in both the seasons, will make good\r\nparents for water-use efficiency trait in breeding\r\nprogrammes. Other good parents include ICGS 76,\r\nTCGS 647 and TCGP 6. SCMR recorded at three\r\ndifferent times under differing soil moisture deficit in\r\neach season showed highly significant correlation\r\nwith each other. Similarly, SLA at different times\r\nalso correlated significantly with each other. SCMR\r\nand SLA were significantly negatively correlated\r\nwith each other and the relationship was insensitive\r\nto time of observation. The results of the present\r\nstudy indicated that SCMR/SLA observations can be\r\nrecorded at any time after 60 days of crop growth,\r\npreferably under moisture deficit conditions. This\r\ngives groundnut breeders a large flexibility to record\r\nthese observations in a large number of segregating\r\npopulations and breeding lines in the field. Thus,\r\nmaking it easy to incorporate these physiological\r\ntraits associated with drought tolerance in breeding\r\nand selection scheme in groundnut."^^ . "2008" . . "160" . "1" . .
