“…As the above F 1 hybrid recorded less number of days for days to 50% flowering, it might have contributed for early fruit harvest. These findings are in consonance with Chowdhury et al (2010) [1] and Suresh et al (2012) [13] . Pennada x Babajipet-2 took more number of days to final picking, while EC-169089 took the least number of days to final harvest.…”

The present study was conducted to assess the general combining ability effects of parents and specific combining ability effects of hybrids for qualitative and quantitative traits and explore their use in hybrid development. Twenty one eggplant hybrids generated by 7 × 7 half diallel and evaluated along with their 7 parents and 2 checks. Seven elite parents viz., Pennada, EC-169084, Bhagyamati, Babajipet-1, Babajipet-2, EC-169089 and Tuni Local were crossed in half-diallel fashion and the resultant 21 hybrids along with parents and two checks viz., Arka Anand and VNR-51 were evaluated for combining ability, heterosis and stability at three locations viz., Nuzvid, Pandirimamidi and Venkataramannagudem during summer, 2017-18. Data were recorded on nineteen quantitative traits viz., plant height, number of primary branches per plant, days to first flowering, days to 50% flowering, days to first harvest, days to final harvest, number of flowers per cluster, number of fruits per cluster, fruit length, fruit girth, fruit length to girth ratio, average fruit weight, number of fruits per plant, fruit yield per plant, fruit yield per plot, fruit yield per hectare, phenols, ascorbic acid and fruit borer damage percentage. A perusal of per se performance revealed that crosses Bhagyamati x EC-169084 (3.45 kg), Pennada x EC-169084 (3.05 kg), Bhagyamati x EC-169089 (2.94 kg), EC-169084 x EC-169089 (2.87 kg), Babajipet-1 x EC-169089 (2.79 kg) and Babajipet-2 x EC-169089 (2.79 kg) were the most promising F1s for fruit yield per plant and other desirable traits over two checks, Arka Anand (2.52 kg) and VNR-51 (3.06 kg). Significant standard heterosis over two checks with regard to fruit yield and its components was exhibited by the crosses viz., Bhagyamati x EC-169084, Pennada x EC-169084 and Bhagyamati x EC-169089 in positive direction. Thus, it is concluded that four hybrids viz., Pennada x EC-169084, Bhagyamati x EC-169084, Bhagyamati x EC-169089 and EC-169084 x EC-169089 exhibited stable performance with desirable per se performance, sca effects and heterosis for fruit yield and other important traits.

“…While, the hybrid (P 1 xP 4 ) had the largest heterosis values relative to their mid-parents and (P 1 xP 3 ) relative to their better parent for total chlorophyll and also the same hybrid (P 1 xP 3 ) relative to their mid-parents had the largest heterosis value for early fruit number and (P 2 xP 1 ) relative to their better parent for the same trait. These results were in agreement with those of Chowdhury et al (2010) who showed heterosis over better parent for fruit yield and Makani et al (2013) who studied heterosis over midparents and better parent for yield and its components in eggplant.…”

“…Heterosis breeding as a tool for genetic improvement in eggplant has been studied by several researchers. Heterosis over better parent was detected by Chowdhury et al (2010) for plant height and fruit yield; Patil et al(2011) for number of branches per plant; Makani et al (2013) studied heterosis over mid and better parent for plant height and fruit yield; Chowdhury et al (2010) for early fruit number and yield.…”

Four parents and their 12 F 1 diallel crosses, involving three parents belonging to the species Solanum melongena L. and one parent belonging to species Solanum macrocarpon L. were used. For heterotic effect, heterosis over mid-parents and better parent were detected in many traits, viz.; plant height(kg), number of branches per plant, and total chlorophyll. Also, heterosis over mid-parents and better parent were detected in early fruit yield per plot(kg), early fruit number per plot and total fruit yield ton/fed. For chemical traits heterosis over mid-parents and better parent were detected in total carotene, anthocyanin content, total nitrogen content, total phosphorus, potassium content and total iron traits. The magnitude of GCA variance was greater than SCA variance suggesting the predominance of additive gene action for most studied traits. Among the varieties, the good general combiner was Balady Dark Long (P 3) for plant height, number of branches per plant, early fruit number per plot, total fruit yield ton/fed and total phosphorus, Balady white Long (P 2) for total chlorophyll, total nitrogen content, potassium content and total iron. Among the varieties, Balady Dark Round (P 1) was the best for early fruit yield per plot and anthocyanin content, In the case of total carotene Gboma (P 4) was the best general combiner. The estimates of specific combining ability effects (SCA) showed superior specific combinations, (P 2 xP 3) for plant height, total fruit yield ton/fed and total phosphorus and (P 1 xP 2) for number of branches per plant, early fruit yield per plot, early fruit number per plot and total iron. While, (P 1 xP 4) was the best for total chlorophyll, total carotene and total nitrogen content, (P 2 xP 4) for potassium content. Regarding, reciprocal effect (rij) the results revealed that highest values recorded for (P 4 x P 1) in the case of plant height(cm), total chlorophyll, total carotene and total iron. While, the hybrid (P 3 x P 1) was the best for number of branches, early fruit yield per plot(kg), early fruit number per plot and anthocyanin content and the hybrid (P 4 x P 2) for total fruit yield(ton/fed) and total phosphorus , the hybrid (P 4 x P 3) for total nitrogen content and the hybrid (P 3 x P 2) was the best for potassium content. Therefore, from general and specific combining ability and some genetic parameters suggested the importance of heterosis breeding for effective utilization of additive genetic variances which had the main role for the improvement of the studied traits in eggplant crop.

ABSTRACT Cytoplasmic male sterility (CMS) is a phenomenon specific to plant reproduction that has been extensively exploited for hybrid seed production. Orf456 was previously identified as a candidate gene mediating male sterility in pepper. To gain further insight of this candidate gene, we carried out experiments to transform Chinese cabbage (Brassica rapa L.). About 30 T1 transgenic lines were obtained and approximately 50 % of T1 transgenic Chinese cabbage lines showed male-sterility. To evaluate pollen viability, three different approaches including plasmolysis test, staining pollen and in vitro germination assay were used. Analysis of the CMS transgenic lines showed that trasgenic Chinese cabbages produced aberrant pollen development while some were unable to produce pollen. In conclusion, the mitochondrial orf456 gene could induce partial male sterility in transgenic Chinese cabbage. Nevertheless, how the orf456 gene precisely functions to induce male sterility and its biochemical function remains to be discovered.
