    Abstract A field experiment was conducted during the summer season of 2014 and 2015 at Kumarganj, Faizabad, Uttar Pradesh, to evaluate the effect of different herbicides on growth and yield of Japanese mint (Mentha arvensis L.) and associated weeds. The experiment was conducted in a randomized block design with 3 replications. There were 10 treatments, comprising pendimethalin 1, 000 g/ha, oxyfluorfen 200 g/ha, oxyfluorfen 250 g/ha, pendimethalin 1, 000 g followed by (fb) clodinafop 60 g/ha, pendimethalin 1, 000 g fb imazethapyr 50 g/ha, pendimethalin 1, 000 g fb clodinafop 60 g fb imazethapyr 50 g/ha, metribuzin 490 g/ha, metribuzin 700 g/ha, weedfree, and weedy check. The soil was silt loam in texture with low organic carbon, nitrogen, phosphorus and medium in potash. The Japanese mint variety ‘Kashi’ was used @ 400 kg/ha in rows, 45 cm apart. Application of preemergence (PE) pendimethalin 1, 000 g/ha and post-emergence (PoE) of clodinafop 60 g/ha followed by imazethapyr 50 g/ha resulted in the highest weed-control efficiency (83.69%) at harvesting stage. Post-emergence application of imazethapyr 50 g/ha resulted in 80–90% control of broad-leaf weeds, but it produced toxic effect on the crop. Among the weed-control treatments, pendimethalin 1, 000 g/ha as a PE fb PoE of clodinafop 60 g/ha, exhibited higher benefit: cost ratio 2.60 over the other treatments, which proved to be more remunerative and economical to the farmers.

    Abstract Marker assisted backcrossing (MABC) was used to transfer the three stem rust (Puccinia graminis tritici) resistant genes Sr25, SrWeb and Sr50 into the popular Indian wheat cv. HUW234. The donor was the CIMMYT breeding line PMBWIR4, and each of the target genes was marked by a simple PCR assay. A three step screening strategy was adopted: the first screen comprised foreground selection, the second used markers lying close to the introgression borders to reduce the extent of linkage drag, and the last was background selection based on 149 informative microsatellite assays. Based on the background selection outcomes, at the BC1F1 generation the proportion of the genome fixed for cv. HUW234 alleles ranged from 55% to 67%. Three BC1F1 individuals were crossed a second time with cv. HUW234, resulting in the identification of six BC2F3 families carrying all three target Sr genes; the proportion of their genome inherited from cv. HUW234 ranged from 86% to 92%. BC2F4 and BC2F5 material was planted at three different locations under both disease-free and artificially induced epiphytotic conditions. Compared to recurrent parent, the improved versions of cv. HUW234 displayed significantly superior resistance to stem rust, and their agronomic performance was as good as, or even marginally better than that of the source cultivar.

    Abstract This paper introduces and motivates the use of hybrid robust feature extraction technique for spoken language identification (LID) system. The speech recognizers use a parametric form of a signal to get the most important distinguishable features of speech signal for recognition task. In this paper Mel-frequency cepstral coefficients (MFCC), Perceptual linear prediction coefficients (PLP) along with two hybrid features are used for language Identification. Two hybrid features, Bark Frequency Cepstral Coefficients (BFCC) and Revised Perceptual Linear Prediction Coefficients (RPLP) were obtained from combination of MFCC and PLP. Two different classifiers, Vector Quantization (VQ) with Dynamic Time Warping (DTW) and Gaussian Mixture Model (GMM) were used for classification. The experiment shows better identification rate using hybrid feature extraction techniques compared to conventional feature extraction methods.BFCC has shown better performance than MFCC with both classifiers. RPLP along with GMM has shown best identification performance among all feature extraction techniques.

  5. Article: The linkage between the stem rust resistance gene Sr2 and pseudo-black chaff in wheat can be broken

    Abstract Recessively inherited gene Sr2 has provided the basis of durable resistance to stem rust (caused by Puccinia graminis tritici) in wheat (Triticum aestivum L.) worldwide. The associated earhead and stem melanism or 'pseudo-black chaff' is generally used as a marker for this gene. Sr2 has been postulated in many wheat cultivars of India including 'Lok 1', based on associated pseudo-black chaff in adult plants, and leaf chlorosis in seedlings. However, dominant inheritance of the resistance factor operating in 'Lok 1', and a 13 : 3 (resistant : susceptible) F2 segregation in the 'Sr2-line' ('Chinese Spring'6 x 'Hope' 3B) x 'Lok 1' cross confirmed that Sr2 was absent in 'Lok 1'. Susceptible plants with a pseudo-black chaff phenotype were observed in F2 populations of 'Agra Local' (susceptible) x 'Lok 1', and the 'Sr2-line' x 'Lok 1' crosses. Most of the F3 families derived from the susceptible F2 segregants with pseudo-black chaff phenotypes were true breeding for the expression of pseudo-black chaff with susceptibility to stem rust. Thus, linkage of pseudo-black chaff with Sr2 in wheat can be broken, and hence, caution may be exercised in using pseudo-black chaff as a marker for selecting Sr2 in breeding programmes.

    Abstract The gene Lr34 has contributed to durable resistance to leaf rust caused by Puccinia triticina in wheat worldwide. The closely associated leaf tip necrosis is generally used as the gene's marker. Lr34 has been postulated in many Indian bread wheat cultivars including 'C 306', based on the associated leaf tip necrosis and a few other field and glasshouse observations. The present study showed monogenic control of adult-plant resistance in 'C 306' to leaf rust pathotype 77-5 (121R63-1). The F2 segregation in the crosses between 'C 306' and the two known carriers of Lr34, 'Line 897' and 'Jupateco 73' 'R' fitted a digenic ratio. The F3 families derived from the susceptible F2 segregants were true breeding for susceptibility, proving the absence of Lr34 in 'C 306'. The cross between 'Line 897' and 'Jupateco 73' 'R' did not segregate for susceptibility. Resistance in the cross 'Agra Local' (susceptible) x 'C 306' was associated with leaf tip necrosis, showing that the leaf rust resistance gene in 'C 306' was associated with leaf tip necrosis, but was different from Lr34. This gene is being temporarily designated as Lr'C 306'. Hence, leaf tip necrosis cannot be considered as an exclusive marker for selecting Lr34 in wheat improvement.

  8. Article: Genetic basis of seedling-resistance to leaf rust in bread wheat 'Thatcher'

    Abstract The bread wheat cultivar 'Thatcher' is documented to carry the gene Lr22b for adult-plant resistance to leaf rust. Seedling-resistance to leaf rust caused by Puccinia triticina in the bread wheat cultivar 'Thatcher', the background parent of the near-isogenic lines for leaf rust resistance genes in wheat, is rare and no published information could be found on its genetic basis. The F2 and F3 analysis of the cross 'Agra Local' (susceptible) x 'Thatcher' showed that an apparently incompletely dominant gene conditioned seedling-resistance in 'Thatcher' to the three 'Thatcher'-avirulent Indian leaf rust pathotypes - 0R8, 0R8-1 and 0R9. Test of allelism revealed that this gene (temporarily designated LrKr1) was derived from 'Kanred', one of the parents of 'Thatcher'. Absence of any susceptible F2 segregants in a 'Thatcher' x 'Marquis' cross confirmed that an additional gene (temporarily designated LrMq1) derived from 'Marquis', another parent of 'Thatcher', was effective against pathotype 0R9 alone. These two genes as well as a second gene in 'Kanred' (temporarily designated LrKr2), which was effective against all the three pathotypes, but has not been inherited by 'Thatcher', seem to be novel, undocumented leaf rust resistance genes.

    Abstract Dried pulverized callus from the sole of diabetic patients showed poor water-uptake (p < 0.001 to < 0.05) and water-loss at different humidities (25% to 100%) and at different temperatures (50 C, 370 C and 50' C), a finding not oberved after ether washing or ether- water washing. The total nitrogen content of the diabetic callus showed no significant variation from the normal controls. The cutaneous insensible perspiration when measured by the unventilated chamber technic of Monash and Blank showed poor diffusive power (p < 0.001).
