Maize inbred lines were evaluated by using line × tester method involving 11 lines and 3 testers for grain yield and its components through estimation of general combining ability (gca) and specific combining ability (sca) effects. Highly significant genotypic differences were observed indicated wide range of variability present among the genotypes. The crosses with high sca effect for grain yield were evolved from high × low general combiner parents which reveled additive × dominance type of gene action. The cross combinations 9MS4-1 × L22, 9MS4-1 × L486, 9MS4-2 × L431, 9MS4-11 × L486 and 9MS4- 15 × L431 with high positive sca effect having high mean values might be used for obtaining high yielding hybrids. The information on the nature of gene action with respective variety and characters might be used depending on the breeding objectives. DOI: http://dx.doi.org/10.3329/bjar.v39i4.22547 Bangladesh J.

Mediterranean Conditions

The diet of millions of people around the world is deficient in selenium (Se). Bread-making wheat has been successfully used in Se biofortification programs under temperate climate to remedy Se deficiency. However, its suitability under Mediterranean conditions and its effect on the grain yield and quality parameters are not well known. In a wheat field in south-western Spain, two foliar Se fertilisers (sodium selenate and sodium selenite) were applied at four application rates (0, 10, 20, 40 g ha–1) in 2010–11 and 2011–12. Results showed a strong and linear relationship between total Se in grain and Se dose for both fertilisers, although selenate was much more efficient. A dose of 10 g sodium selenate ha–1 was able to increase significantly the Se in grain to close to the recommended values, although Se loss of 28% during the milling process might be expected. Grain yield was not negatively affected by fertilisation, but grain protein and dry gluten were slightly negatively affected, but only in the dry year. Alveograph parameters were either not affected or slightly favoured by Se fertilisation in any studied year. Bread-making wheat is a good candidate to be included in biofortification programs under semi-arid Mediterranean conditions.

Malt Barley

Malt barley production requires a technology increasing nitrogen use efficiency, because of a high sensitivity of barley total grain yield and quality parameters to external growth factors. In the conducted study an effect of two P fertilizers on the background of N application on total and technological grain yields were studied. The highest total grain yield was harvested on plots fertilized with 60 kg N/ha, irrespective of the P fertilizer type. However, the technological grain yield showed a high year-to-year variability; the highest was recorded in 2001 on the plot fertilized with 60 kg N/ha and the P-PAPR fertilizer. The N and S concentrations and N:S ratios in immature grains at harvest were used to evaluate both yield types. Nitrogen concentration in the final total yield allowed making yields prognosis with the highest probability. The maximum yields of technological malt barley were attainable provided that total S concentration in immature grains at harvest was above 0.23% and the N:S ratio was narrower than 8.0.

An investigation was carried out to assess the combining ability and nature of gene action in baby corn (Zea mays L.) genotypes, by making crosses of eight inbred lines namely, HKI 3209, SML 1, EC 595979, CM 128, VQL 1, G 18 seq C5 F 76-2-2-1-1-2-BBB, HKI 209, in diallel mating design (without reciprocal crosses) by following Griffing Model–I and Method–II during rabi season 2013-14 at the experimental farm of BAC, Sabour, Bhagalpur (Bihar). The crosses were evaluated in a randomized complete block design (RCBD) to assess the combining ability and nature of gene action. Based on general combining ability, parents CM 128 and VQL 1 were best parent forbreeding programme for yield and quality improvement. The specific combining ability also indicates that hybrid CM128 x VQL1 was best specific combiner for baby corn yield (4.11q/ha), fodder yield (50.91q/ha) as well as for better quality. The crosses CM 128 x HKI 209 recorded the high mean (7.35%) and SCA effects (2.57 ºBrix) for quality traits. The gene action analysis also revealed preponderance of non-additive gene action for yield and its contributing characters.
