“…Most of the hybrids giving negative heterosis suggesting hybrids matured early than better parent or check variety was also observed in work of Priyanka et al, (2014), Veeresha et al, (2015) Waza et al (2016) and Bano and Singh, (2018). However, Soni and Sharma, (2011) observed positive standard heterosis in most of the rice hybrids studied by them.…”

“…Negative standard heterosis for plant height in rice has been observed by Rahimi et al (2010), andWaza et al (2016) in their studies. However, the positive significant standard heterosis and heterobeltiosis has also been reported by Kumar et al (2012).…”

“…28 hybrids exhibited the positive significant standard heterosis, out of which seven hybrids gave standard heterosis of more than 100 per cent; more than 80 per cent standard heterosis was found in three hybrids and more than 50 per cent standard heterosis was found in two hybrids. Kumar et al, (2012), Waza et al (2016) and Akanksha et al (2018) have reported a positive standard heterosis and heterobeltiosis for most of the hybrids studied by them. However, more number of hybrids showed the cnegative standard heterosis and heterobeltiosis in work of Priyanka et al (2014), and Bano and Singh (2018).…”

In the present study, heterobeltiosis and standard heterosis were estimated on 36 F 1 s obtained through half-diallel mating design for yield and quality traits. For yield per plant trait, seven out of 36 hybrids recorded standard heterosis of more than 100 per cent. CSR-30 x HUBR10-9 (160.09 per cent) recorded the highest significant positive standard heterosis over yield check Pusa Basmati-1. For quality traits, hybrid Pusa Basmati-1121 X Pusa Basmati-1509 performed well, as it exhibited a significant desirable standard heterosis for kernel length, kernel length after cooking, kernel breadth after cooking, and length/breadth ratio. Other hybrids that performed well for quality traits were Pusa Basmati-1 X Pusa Basmati-1121, Type-3 X Pusa Basmati-1121, Type-3 X Pusa Basmati-1509 and Taraori Basmati X Pusa Basmati-1121. 17 hybrids were found to have the desired intermediate range of amylose content (20-25 per cent) and 22 hybrids showed a desirable range of 4-7 for alkali spreading value, based on per se performance.

“…Therefore, selection of only few parents having high genetic potential in crossing programme is essential. In order to exploit the maximum heterosis using CMS system in the hybrid breeding programmes, we must know the combining ability effects of different male sterile and restorer lines for various traits [11,12]. Among the various techniques of combining ability analysis, line × tester analysis has been widely used for screening of germplasm to identify valuable donor parents and promising crosses [13,14,15].…”

Rice is one of the most consumed food crops in the world and therefore possesses huge socio-economic relevance. Combining ability estimates provide the basis for selection of suitable parents in breeding programmes for rice improvement. The experiment was conducted to evaluate the combining ability effects for various agro-morphological traits in some genotypes of rice. Thirty-four male parents were crossed with the four CMS lines in line × tester matting design and 136 cross combinations were obtained. For most of the traits, SKUA-7A showed desirable GCA effect among the female parental lines; while RL-1, RL-2, RL-11, SKUA-497, SKUA-494, SKUA-496 and SKUA-420 showed desirable GCA effect amongst the male parents. Cross combinations SKUA-7A × RL-3 and SKUA-11A × RL-5 revealed desirable heterosis for most of the traits viz., grain yield, number of effective tillers plant-1, panicle length and number of spikelet panicle-1. These cross combinations also possessed desirable values of SCA effect. In general, the cross combinations showing desirable specific combining ability effects also reveal better per se performance for the respective traits.

“…Moreover, the most important challenge for current system of agriculture and seed production is that the dissemination and adoption STRVs is low mainly due to the lack of information and non-availability of seeds amongst farmers [5,91,163]. The existing system of agricultural extension and seed supply need to be aligned in a way to successfully deliver the proven stress tolerant technology to farmers.…”

Abiotic Stress Tolerance-Progress and Pathways of Sustainable Rice Production

Rice is globally a major food crop and its production has progressively been affected by various types of abiotic stresses especially drought, flooding, salinity, heat and cold in most of the cultivable rice ecosystems. The incidence, intensity and duration of these stresses are anticipated to aggravate due to climate change consequences, demanding resilient yields in these situations to be essential. Present paper deals with reviewing various types of abiotic stresses and their mitigation strategies for enhancing and stabilizing rice production in stress prone areas. Review of available literature pertaining to the study area has been used as research methodology for this paper. The available literature suggests that stress-tolerant varieties can serve as the most viable strategy to contribute in coping with the problem of abiotic stresses. Although, good progress has been made in the development of stress-tolerant rice varieties (STRVs) and incessant efforts are being made to spread these varieties in target areas, adoption by farmers is yet to meet expectations. Advantage, affordability, awareness and availability are the main factors responsible for adopting of any technology. The adoption of stress-tolerant varieties has not reached its potential, predominantly due to the lack of awareness and non-availability of seeds amongst farmers. Strategic and intentional collaborations should be ensured for scaling the sustainable delivery and diffusion of STRVs. A promotional roadmap that ensures the linkages between private and public seed sectors remains the key factor for its successful adoption. Similarly, strengthening of formal, informal and semi-formal seed systems is crucial to accelerate the dissemination of these varieties. There is an imperative need to create strategic plans for the development of varieties possessing multiple stress tolerance. Significant investments for sustainability of rice production in stress prone areas form the essential component of long-term agricultural development. The sooner these investments and strategies are accomplished, the greater the gains are expected.
