“…Heterosis breeding is a tool used for onion breeding scheme . Because of the intricacies of the breeding system, such as the presence of several little hermaphrodite flowers, difficulty in physical emasculation and crosspollination (Manjunathagowda & Anjanappa, 2020), biennial crop life cycle and high inbreeding depression (McCallum et al, 2007), hybrid seed production is minimal; these breeding complexities could be overcome by efficient use of genomic technologies and molecular markers (Khosa et al, 2016) linked to male sterility traits which are being in use to speed up onion improvement programmes.…”

“…The male sterility trait avoids obstacles in the breeding system, such as laborious hand emasculation and hand pollination, and prevents uncontrolled selfing or sib mating, the male sterility trait is a virtue for F 1 hybrid seed production (Manjunathagowda & Anjanappa, 2020). The CMS-S and CMS-T systems of genetic nuclear cytoplasmic sterility are being in use for hybrid seed production of onions.…”

Onion (Allium cepa L.; 2n = 16) belongs to the family alliaceae, and order asparagales; and the Allium is the monocot's largest genus, comprised of 920 species (Govaerts et al., 2005(Govaerts et al., -2014. Among them, onion (A. cepa L.), garlic (A. sativum L.), bunching onion (A. fistulasum L.), leek (A. porrum L.) and chives (A. schenoprosum L.) are widely being in cultivation. Among alliums, the onion has the largest economic potential, with 70% share value, followed by garlic (25%) (FAOSTAT, 2016), the consumption of onions has been steadily increasing over the world, most likely due to the nutritional benefits (Manjunathagowda et al., 2019); presence of an unique dietary flavonoids source and quercetin compounds (Slimestad et al., 2007); and medicinal therapeutic values such as lacrimatic, anti-cancer, antibiotic and anti-cholesterol activity (Grifths et al., 2002; Perez-Gregorio et al., 2010).In the world, onion acreage of 4.96 million hectare (mha) with production of 93.17 million tonnes (mt), the world's biggest onion growers are China (23.91 mt) and India (19.42 mt) (FAOSTAT, 2016).But the productivity of major onion-producing countries, China (22 tonnes per hectare (t/ha)) and India (16.18 t/ha), is low compared to Netherlands (49.70 t/ha) (National Horticultural Board, 2017), the United States (56.40 t/ha), Iran (37.95 t/ha) and Egypt (36.71 t/ha) (National Horticultural Board, 2018). This could be because of the largest onion-growing nations (China and India) have been largely covered by open-pollinated varieties, which produce poor yields per unit area and are influenced by seasonal short-day environmental conditions, as compared to countries that have adopted F 1 hybrids using the male sterility trait

“…Regarding Ms locus identification, marker-assisted selection made it possible with RFLP [ 223 ], CAPS [ 227 ], SCAR [ 262 ], SNPs [ 263 ], and other PCR-based markers [ 226 , 264 , 265 , 266 ]. Recently, new primers for the cytoplasm [ 225 , 267 ] and the Ms locus [ 264 , 265 ] are being utilized for the identification of the cytoplasm and the Ms locus [ 183 , 268 , 269 , 270 ]. Although they are reported to be in complete linkage disequilibrium with the Ms locus, new PCR markers linked to the Ms locus are still being reported.…”

To address the complex challenges faced by our planet such as rapidly changing climate patterns, food and nutritional insecurities, and the escalating world population, the development of hybrid vegetable crops is imperative. Vegetable hybrids could effectively mitigate the above-mentioned fundamental challenges in numerous countries. Utilizing genetic mechanisms to create hybrids not only reduces costs but also holds significant practical implications, particularly in streamlining hybrid seed production. These mechanisms encompass self-incompatibility (SI), male sterility, and gynoecism. The present comprehensive review is primarily focused on the elucidation of fundamental processes associated with floral characteristics, the genetic regulation of floral traits, pollen biology, and development. Specific attention is given to the mechanisms for masculinizing and feminizing cucurbits to facilitate hybrid seed production as well as the hybridization approaches used in the biofortification of vegetable crops. Furthermore, this review provides valuable insights into recent biotechnological advancements and their future utilization for developing the genetic systems of major vegetable crops.

“…These hybrids were unable to get commercial popularity and adoption among the onion growers at national level (Khar and Saini 2016). Manjunathagowda and Anjanappa (2020) identified male sterile lines from Indian onion population. They observed that male sterile flowers had longer style, narrow stigmatic knob, produced functionally non-viable pollens and perianths did not open fully.…”

Onion (Allium cepa L.), a major member of monocot family Amaryllidaceae, is an important bulbous vegetable cropused in almost every Indian kitchen. Being cultivated since antiquity, farmers rely on growing open pollinated varietiessince hybrid development in this crop has not gained pace. Among important vegetables, F1 hybrid developmentremains underutilized in onion especially in India and other developing countries as compared to other onion growingcountries. Development of commercial hybrids in onion principally depends on the availability of suitable inbredlines against the backdrop of stable male sterile system. The future scope of commercial onion hybrids needs to befocused comprehensively for the identification of male sterile lines from Indian onion population by utilizing modernbiotechnological tools. Molecular markers distinguishing cytoplasm and linked to restorer of male sterility, Ms locus,are important. Release of commercial hybrids from public sector would play a great role for breaking yield barriers andsignificant enhancement of productivity of onion under changing climate scenario and increasing domestic demand.
