“…This might be due to the additive effects of the genes from the two parents of the respective crosses controlling pod formation and maturity [29]. Kernel yield of the F1s, like the parents, did not show any significant difference at 10 dS/m salinity stress.…”

Abstract:The study was performed with seven groundnut varieties/genotypes and F1s derived from crossing in all possible combinations without reciprocal among the mentioned varieties/genotypes. The objective was to assess whether low Ca 2+ content and/Na + ratio of leaf tissue or stem tissue determine salinity tolerance in terms of economic yield (kernel yield) in groundnut. It revealed that the varieties, "Binachinabadam-6", "Binachinabadam-5" and the F1 G2 × G3 were most tolerant based on kernel yield under 8 dS/m and 10 dS/m salinity stresses. These two tolerant varieties and the F1 also showed lower Ca 2+ and Ca 2+/Na + ratios in leaf tissue, which indicated lower Ca 2+ and Ca 2+/Na + ratio of leaf tissue determined salinity tolerance in terms of kernel yield in Spanish type groundnut. These findings could be applied in future plant breeding applications for screening salt tolerant Spanish type groundnut genotypes.

“…This result of relative performance agrees with Haque (2006). Plant height number of leaves and pod yield were gradually decreased in groundnut with increasing salinity dose (Singh et al, 2010;Azad et al, 2014.). Table 2 showed that the relative plant height at growth stages is the highest (97.41%) at pod filling stage and the lowest at vegetative (64.50%) stage which followed by flowering (68.43%) and pre-sowing stage (74.25%), respectively.The interaction effects of variety × salinity dose x growth stage on plant height also presented in Table 2, Dacea-1 and Zhingabadam showed rapid decrease with the increase in salinity than Binachinabadam-3.…”

The study sought to evaluate the response of three groundnut genotypes (Binachinabadam-3, Dacca-1 and Zhingabadam) to various salt concentrations (D0 – Control, D1 – 2.5 dS/m, D2 – 5.0 dS/m, D3 – 7.5 dS/m, D4 – 10.0 dS/m, D5 – 12.5 dS/m) through observation of morphological and physiological characters. Based on relative performance of yield contributing characters and nutrient contents of leaves and stem, Binachinabadam-3 emerged to be a tolerant variety and based on root shoot characters, Dacca-1 appeared as tolerant while Zhingabadam always performed as sensitive variety. Salinity treatments had most adverse effects at flowering stage and followed the trend of sensitivity as flowering stage > vegetative stage> pre sowing stage > pod filling stage. All varieties were found to be tolerant up to salinity level of 7.5 dS/m.

“…Hence the influence of varying salinity level on maize production needs further intensive studies to correlate the role of tolerant maize varieties on higher yield potential. A comprehensive genetic study is a prerequisite to determine the nature of inheritance of a trait that will lead to choose the right breeding improvement strategy for the crop (Azad et al, 2014). As Table 9.…”

A diallel cross was produced using diverse maize (Zea mays L.) germplasm of saline tolerant and saline susceptible maize lines as parents. Agronomic performance of the offspring of the diallel cross was examined. Eight germplasm lines bearing diversified agronomic traits of five known tolerant and susceptible lines were involved as parents of the diallel cross that was evaluated at three different ecological areas viz. Gazipur, Benerpota, and Kaliganj. CZ-29 and CZ-26 had positive and significant general combining ability (GCA) effects for yield in both the saline environments, where CZ-12 possessed negative and significant GCA effects for yield in the same areas but none of the parents exhibited either significantly positive or negative GCA in Gazipur location. Of the saline tolerant lines evaluated, CZ-29 was a good source for increased yield with significant and positive GCA values in both the saline environments that was also responsible for dwarfness and earliness in all locations. CZ-26×CZ-24 yielded well except at Benerpota with an additional benefit of shorter plant type across all environments. Hybrid CZ-29×BIL-65, however, was consistent and promising over the environments for bold seed and higher yield that ranked 2 nd at Benerpota (4.81 t ha -1 ) and Kaliganj (6.73 t ha -1 ) and 3 rd at Gazipur (7.40 t ha -1 ) location for yield having significant positive specific combining ability (SCA) effects at Gazipur and Kaliganj. Moreover, six hybrids either significantly or not consistently decreased yield over the locations with negative SCA. However, considering the overall performance of the hybrids, the involvement of saline susceptible or tolerant parents was not consistent in the present study. Crosses between saline tolerant lines did not produce any tolerant hybrids or dwarf parents did not produce dwarf hybrids except CZ-29×CZ-36 that was able to produce shorter hybrid for all the locations. Therefore, among the lines evaluated in this diallel cross having a distinct different genetic background, CZ-28 and CZ-29 contributed to earliness; CZ-29 and BIL-65 reduced plant height; CZ-12 increased seed size; CZ-26 and CZ-29 improved yield. Thus, these lines should be useful sources of alleles for pyramiding, earlier maturity, shorter plant heights, increased seed size and improved yield into desired breeding lines.
